I gotta tell ya man, as a 25yr mechanic, you have the most detailed instructional videos ive ever seen on youtube. You explain things in the same way i explain things to young apprentices so that they understand it right the first time. Never skipping over anything, and knowing all the small details that need to be pointed out is so key to learning. Well done brother!
Man I appreciate you taking the time and the effort to explain all this! I paid so much attention that I can't actually believe it. I came here just to understand more about preload on divorced suspensions and ended up watching the whole clip. Thanks, you have cleared all my doubts!
GREAT VIDEO. FINALLY someone who explains how to install and adjust the rear coil overs. I really don't know why so many videos just skip them. I read somewhere random that I just had to adjust the height of the rear shock. Totally left out of wack my spring. It kept banging hard, Until I finally found your video explaining how to properly install them. I just went ahead and took them off and adjusted them. Kinda perfect now, only feeling how soft or hard i need to leave em. Great video, learnt a lot !Will recommend to friends
I got the same year and model in black with the BC BR model coilovers. I appreciate all the videos you have made on your car! Love the detail and dedication!!! Helped me a lot knowing all these things. Keep up the good work 💪🏼
Words can not describe how informative this video was for me I’m 19 with a stances Honda civic 2011 but this has made me understand so much more of my car thank you so much this work is unmatched 🙏🏿
Bro I been looking forever and ever on how to do my coilovers and was upset with myself thinking I got the wrong ones bc I couldn’t understand it. Thank you.
Each to their own but I've always used shock body to dictate bump stop engagement, then spring perch (preload) to adjust compression travel vs rebound travel. -Adjusting ride height using shock body adjustment only is a good way to get the tyre to collide with body work. -Adjusting spring perch to a generic 5mm is a good way to either not have enough compression travel (no grip), or not have enough rebound travel (no grip) depending on spring stiffness.
Very useful video. I found this because I searched how to adjust the preload because the inner rear wheel has been spinning too much in tight corners. So I'm hoping this makes a difference to the performance of my Skyline.
Thank you so much man. Super helpful and clear information. Getting under my genesis coupe tonight to play with the ride and stance. She's my daily race car so I'm going for a tire efficient aggressive with sporty height. Your simple clear explanation and example gave me the confidence to say eff it and go for it. Best friend and music collaborator gonna create some good times off this. Thanks again Deffffffinitely subbed
Unfortunately most people (and most cheap coil over manufactures them selves) don't know how to set up these types of coilovers properly. The required bump/droop ratio (2/3 bump to 1/3 droop is usually a good guideline) should be set by first installing the coilovers on the car with no springs fitted. Adjust the coil over in the damper body so the piston is at the correct point for the desired ratio at the desired ride height. You can fit the wheels and fully compress the suspension at this point to check clearance. If all is well, refit the springs and use the spring "preload" to bring the damper piston back to the required point determined above (set the ride height). Doing this allows you to set the height without altering the bump/droop ratio like you are doing when you adjust the height with the lower damper body in the video. You're either taking away bump or droop doing it as you are. You may find you need a helper spring if the spring now separates from the seat at full droop. Don't worry about using preload to adjust height either, it makes no difference how much preload the spring has once the weight of the car is compressing it, it will be the same length (as long as it's the more common linear spring type rather than progressive). Suspension Secrets website have some great articles about this on their website, it takes a bit of setting up but is absolutely worth it to get the most out of your coilovers. Usually the higher end brands like KW/NITRON etc use single body dampers so none of this is required, they set the bump/droop for you and only adjust height via the spring perch. These dual body designs are just used for cheapness so they can carry the design over to other models, but for that reason setting them up as above is pretty important.
This is correct. Blows my mind how much misinformation is out there on this and continues to be repeated. What hes doing DOES achieve what most people are buying coils want and thats to just lower a car. I'd wager most dont know any better, may just not care about doing it this way, or will never use the shock in a situation where you want full use of the shock travel.
@@daokochan6245 the shocking part is that 90% of coilover manufacturers don't even tell you this. Maybe they think it's too complicated for the average buyer but it makes such a difference getting maximum travel out of the coilovers
Dude thanks for making this vid,i just recently upgraded to raceland coilovers on my 2011 Genises Hyundai coupe 3.8 r spec and i installed them my self which wasn't the best thing but thanks to you i was able to get it done thamk you keep up these vidoes for guys like us.
@@milanmastraccihonestly, it’s quite impressive. I originally watched years ago on the 9th gen civic si, bc I had just gotten one and wanted to know everything haha. Now I’m modifying a focus st, and im at the coilovers. I thought to myself, “I wonder if he still makes videos..” haha the answer is yes.
Yeah I love this guy compared to other people his voice is pleasant and he explains everything so good and knows how to explain it very knowledgeable man
Hey Milan 👋 Great job explaining camber, caster, and toe in easy to understand terms. I appreciate you showing how the parts you added contribute to the overall suspension geometry as well. The new wheel and tire combo looks great too! Especially seeing it at ride height at 4:50 🤤 What wheels and tires are they, and could you share the sizes and specs? You keep giving me more and more ideas for my ninth gen, haha! 😆
Thanks man! I'm happy to hear that 👊 They're Enkei TS-10s in a 17x8+45s, with a 245/40R17 Bridgestone RE71Rs on all 4 corners. I'm a bit fan of wheels that are a multiple of the lug nuts. (5 lug nuts = 5, 10 or 15 spoke wheels)
Thank you too, man! 👊 There’s so many options out there for wheels and tires it can get paralyzing, lol 😆 The Acura 5 spokes you had on there before make even more sense now too. Looking forward to seeing how the TS-10s and Bridgestones perform in future videos, and wishing you and yours a Merry Christmas and a very Happy New Year!
And if the collars simply spin together on the threaded strut body instead of rotating the strut body to raise or lower the front, is it time to disconnect the strut from the knuckle? Or is there another method to prevent the need to do that?
What is the torque spec on the big bolt on the rear shock absorber? Thank you for what might be the most helpful instructional video on coilover adjustments on all of youtube.
Thanks for this!! I buy my first Coilovers and this info is very important for me. Now I have to make sure everything is gonna be ok when I put them on the car. If I have a question I will let you know so maybe you could help me, thanks 🙏🏽🙌🏾
Please help...my son Mr. Money bags bought k-tuned shocks and springs, but in your video, the back adjustments with the key for the springs were on top where the seating adjustment for what he got is at the bottom. Is this OK?. I'm mechanically knowledgeable being a deisle mechanic (snow removal biz) but he asked me to help him and use my garage...and I just want him to be safe
So I installed these same coilovers about a year ago, changing my tire size so I'm adjusting the rear set up...My passenger side shock body won't turn either way, everything works as it should on the driver side set up though. Any recommendations?
Question, the arm to subframe mount points… do you loosen then tighten them with the cars weight on all 4 wheels to prevent bushings tearing or do you keep it loose and tighten it when fully extended with no weight ? Just replaced most of the bushes on my car and don’t want them wearing out quicker to to un necessary stress
If you are torquing control arms that have rubber bushings, yes, however with aftermarket arms with polyurethane or spherical bushings, you don't need to.
Do the front coilover’s preload have to be adjusted or reset after adjusting or changing ride height? Like you would do with the rear divorced setup.. I recently swapped wheels on my coupe- and would like to lower it, but I’m wondering since I’ve already set the preload if I can just lower it.
I like how you adjust the rear coilovers preload vs how BC explains it. Turning the damper to lift/ compress the spring bucket 5mm is easier than jacking the spring bucket up, and then putting the bolt through the lower mount. Especially when working on a car that’s on a lift. Great stuff man, much appreciated! 👌🏽
Have you checked the collars to make sure they are tight? I know this kinda sucks, but I've seen coilover top hat nuts not be properly torqued, which means they have to be removed. On another note, did you undo the stock control arm bolts (given you're using arms with rubber bushings), install the coilovers at the desired ride height, and with the suspension under load, then tighten the bolts?
From your video,I kinda understand the front adjustment - Preload first followed by height adjustment, and i can adjust the height independently without messing the preload But for the rear, it seemed like height adjustment first followed by turning the absorber to match the bolt, lastly rotating the absorber to achieve the preload. My question is, if I want to adjust my rear height again, I will need to make adjustments to my preload again as this is the last step?
Hey K Y Lee, Yes you will have to adjust the preload if you change the ride height for the rear suspension. For the front, if you want to adjust the ride height, you do not need to adjust the preload. Hope that helps!
@milanmastracci @milanmastracci thanks for the response. I saw a video from BC North Amercia, and the rear suspension installation sequence is a bit different from yours. Your video - height adjustment/ lower the absorber to match the bolt/ Preload achieved by raising the absorber up Other BC videos - height adjustment/ preload by using a jack / either lower or raise absorber to match the bolt. Is this somewhat the same method as yours?
It’s essentially the same thing, except instead of using a jack to load the spring, he loads it by shortening the shock. Honestly more accurate than a jack imo
Why didn’t you cover setting the bump? The way you’ve done it you could just blow through the travel and catch your wheel. Surly bump should be the first thing set with the shock mounted without the spring?
Dude thank u so much for not only this video but all the videos you have done you have made it so much easier for DIY people like myself to do exactly that
Where does the 5 mm number come from when adjusting the preload for the rear spring and shock absorber? I get the 160 number but why are you subtracting 5 from it?
Agree with everything you said except for the rear toe adjustment, it’s actually adjusted on the rearward nuts on the trailing arm where the knuckle attaches, the 17mm and 24mm nuts that are on top of each other is where the factory adjustment point is for rear toe. Otherwise very informative, will be using your tips when installing my coilovers.
Hey Angel, right you are!! I forgot to mention that area too. You can dial in the toe from both spots, first from the knuckle area, and if you need more or less, the entire trailing arm can be repositioned.
Dude, thanks so much for making this video and being a great teacher! I've struggled with some of these concepts, so it really helped! Now I just need to find those little coilover adjustment tools as the 2 cars I've purchased came with some coilover, but no tool to adjust :/
been watching you since I was young, learning how to drive manual, rev matching and double clutching. And now its come full circle with me watching your videos learning how to mod my car hahah. we’ve come a long way, i’m happy you still make videos, they are as insightful as ever
Just a heads up, you adjust ride height with spring and the base is for tuning bump/rebound travel. This applies to both coil over & divorced designs. If you adjust height at the base you'll have the wheel colliding with the body work. You use it to set a limit for bump travel. If your spring is loose at your desired ride height, that's what helper springs are for. Spring pre-load is not a thing, just an outcome of height settings.
This is the most informative comment I've found between Google and TH-cam. I figured helper springs would be the cure, but nothing told me I need them... Thanks.
Perhaps I am not understanding. On the rear divorce, why adjust the damper after adjusting ride height? You eventually have to adjust the damper for spring preload. Doesn't that defeat the previous step of adjusting the damper for ride height?
You don't know how useful this video was saved me so much, first time doing anything like this and completely messed up installing the rear but hopefully now we are chilling
Thanks for this video, very helpful. I have watched many of your videos on the 370z and after months of collecting parts and finally getting them on the car, I have to say thank you. Your videos have helped me out tremendously. I'm super stoked that my ride is set perfect and feeling good. loving my new coilovers. Much appreciated.
Hey @milanmastracci - Question in regards to adjusting the rear divorced setup, so after changing the spring for ride height, I see some people undo the bottom bolt that holds the shock and spin it that way to align it with the control arm hole again, whereas you just undid the collar and spun it whilst it's bolted on. Do both ways achieve the same thing? I am thinking your way is much easier and no need to re-bolt things.
Milan Merry Christmas and Happy New Year from Jake and i at Eliminator Performance hope you got your snowblower in good running condition with all this drifting snow we are getting here in Port Colborne. Our neighbour just finished shovelling out his side door entry drift that was 7 feet high luck he could get out of his entry door.
Merry Christmas and happy new years to you guys too! Yes thank you guys for the help. I was able to band air the shift fork for the mean time. I had a good 4 feet in front of my main entrance, and about 5 feet in front of my garage doors. Wasn't fun to clear lol
I’m tired of seeing this misinformation spreading through the car community. It’s important to note that adjusting your coilover this way is a recipe for poor handling or a damaged fenders. You adjust shock lengths with the lower collar first, achieving a proper bump and droop sweep with the bump stop hitting before the tire hits your fender. Then Adjust height with the upper collars/spring perch collar. The spring doesn’t necessarily need to be captive and wont clunk if you don’t remove your sway bars. But it is recommended to get a helper spring if your height is too low for the spring to remain captive. Again… Lower collar = shock length Upper collars = ride height
great video Milan thank you, i noticed that you linked the 06-11 skunk 2 camber arms but i did some research and they make the arms for the 12-15 as well, do the 8th gen arms really work on the 9th gen?
How do I know if my back shock is in right height? Correct me if I'm wrong but the height of the car ajusts on the spring, and the shock height is soft/hard settings? 🤔
Just a question why the others when adjusting the lowering of the Devorce suspension is only the spring and not the Strut, it was said in the video that when you adjust the spring, you also need to adjust the Strut
When adjusting ride height in the rear, making the spring longer makes the car lower or compressing it shorter makes the car lower? Hope that makes sense
Thank you for share this with us 😎 ! In my personal opinion i really prefer the old school suspension that Honda what did use before coilovers front and rear without the spring in the rear easy and simple !
You and me both! It's insane how many different rear suspension designs there are, and how some are easier to work on than others! Ideally, multilink rear would be nice for these cars, especially since it would eliminate the heavy steel trailing arm, but oh well lol
Man this is amazing like always just seeing these videos really help me out and understand more about my car sounds kinda selfish but I like knowing I have have a guide from someone else good work man🔥
Nice video , I have the same coilover on a x5, but the rear tires are robbing with the fender when im driving and go over highway imperfections, should I raise the rear or should i just put more pressure to avoid too much damper in the rear? Thanks
Honestly, I'd just ditch the way that so many people and manufacturers get wrong. What I mean is that...... A) The lower spring perch is actually what should be adjusted for ride height. B) The lonesome lower locking collar is actually what should be adjusted to dial in shock travel. C) You are likely rubbing because you haven't set your shock height to hit your bump stops before your tire rubs. There are some really good videos that cover how to do this. I'm still learning and far from an expert but I can tell that well over half the content on here on coilovers is incorrect. Mike Kojima with MotoIQ is phenomenal and explains a really easy way to adjust your dampers once you dial in your ride height. Also, depending on your desired ride height you may have to switch to different springs. I should mention that you of course can shorten your shock length but know that I'm doing so you are sacrificing shock travel. Hope this helps you in some way. I've been trying to dial in my godspeed/bracing/custom coilovers for the past 1.5 years with limited info/resources for my car. Good gods has it been an adventure and will eventually post my experiences on a couple forums in the future.

Awesome video.. I have had a very difficult time trying to find a video on how to adjust ride height for a divorced setup. Thanks so much
Don't remember how many times I have watched this. So properly made video
Dude thank u so much for not only this video but all the videos you have done you have made it so much easier for DIY people like myself to do exactly that
Glad I could help!! Feel free to share it with your buddies too so they find this help 🤙
Where does the 5 mm number come from when adjusting the preload for the rear spring and shock absorber? I get the 160 number but why are you subtracting 5 from it?
Can anyone answer this? I’d also like to know
Seriously one of the simplest and best explained coil over set up videos ever. Thank you
Agree with everything you said except for the rear toe adjustment, it’s actually adjusted on the rearward nuts on the trailing arm where the knuckle attaches, the 17mm and 24mm nuts that are on top of each other is where the factory adjustment point is for rear toe. Otherwise very informative, will be using your tips when installing my coilovers.
Hey Angel, right you are!! I forgot to mention that area too. You can dial in the toe from both spots, first from the knuckle area, and if you need more or less, the entire trailing arm can be repositioned.
I just started rotating my divorced shock body, expecting to change the ride height. Coilovers make no sense, lol
Dude, thanks so much for making this video and being a great teacher! I've struggled with some of these concepts, so it really helped! Now I just need to find those little coilover adjustment tools as the 2 cars I've purchased came with some coilover, but no tool to adjust :/
been watching you since I was young, learning how to drive manual, rev matching and double clutching. And now its come full circle with me watching your videos learning how to mod my car hahah. we’ve come a long way, i’m happy you still make videos, they are as insightful as ever
That's awesome Joaquin!! Happy to hear you're learning to upgrade your car 🙌
Just a heads up, you adjust ride height with spring and the base is for tuning bump/rebound travel. This applies to both coil over & divorced designs.
If you adjust height at the base you'll have the wheel colliding with the body work. You use it to set a limit for bump travel.
If your spring is loose at your desired ride height, that's what helper springs are for. Spring pre-load is not a thing, just an outcome of height settings.
This is the most informative comment I've found between Google and TH-cam. I figured helper springs would be the cure, but nothing told me I need them... Thanks.
So I should have the lower locking but all the way a the bottom and adjust the locking nuts under the spring for ride height?
this is correct, i just made a comment saying the same
Man I'm so freaking lost
Just wanna say that I installed bc’s on my 2008 accord coupe and you’re video was very helpful and informative.
Thank you so much, seriously.
I'm happy to hear that my video was helpful to you brother! Cheers
Perhaps I am not understanding. On the rear divorce, why adjust the damper after adjusting ride height? You eventually have to adjust the damper for spring preload. Doesn't that defeat the previous step of adjusting the damper for ride height?
You don't know how useful this video was saved me so much, first time doing anything like this and completely messed up installing the rear but hopefully now we are chilling
Thanks for this video, very helpful. I have watched many of your videos on the 370z and after months of collecting parts and finally getting them on the car, I have to say thank you. Your videos have helped me out tremendously. I'm super stoked that my ride is set perfect and feeling good. loving my new coilovers. Much appreciated.
Hey @milanmastracci - Question in regards to adjusting the rear divorced setup, so after changing the spring for ride height, I see some people undo the bottom bolt that holds the shock and spin it that way to align it with the control arm hole again, whereas you just undid the collar and spun it whilst it's bolted on. Do both ways achieve the same thing? I am thinking your way is much easier and no need to re-bolt things.
i have a clunk after installing coilovers on my mini...i'm hoping this fixes it 0_0
Turns out they were not preloaded..but didn't fix the issue :(
Milan Merry Christmas and Happy New Year from Jake and i at Eliminator Performance hope you got your snowblower in good running condition with all this drifting snow we are getting here in Port Colborne. Our neighbour just finished shovelling out his side door entry drift that was 7 feet high luck he could get out of his entry door.
Merry Christmas and happy new years to you guys too! Yes thank you guys for the help. I was able to band air the shift fork for the mean time. I had a good 4 feet in front of my main entrance, and about 5 feet in front of my garage doors. Wasn't fun to clear lol
I’m tired of seeing this misinformation spreading through the car community. It’s important to note that adjusting your coilover this way is a recipe for poor handling or a damaged fenders. You adjust shock lengths with the lower collar first, achieving a proper bump and droop sweep with the bump stop hitting before the tire hits your fender. Then Adjust height with the upper collars/spring perch collar. The spring doesn’t necessarily need to be captive and wont clunk if you don’t remove your sway bars. But it is recommended to get a helper spring if your height is too low for the spring to remain captive.
Again…
Lower collar = shock length
Upper collars = ride height
So what is a good performance/stiff tolerable spring kg for a big v8 vehicle? (Lex LS460)
great video Milan thank you, i noticed that you linked the 06-11 skunk 2 camber arms but i did some research and they make the arms for the 12-15 as well, do the 8th gen arms really work on the 9th gen?
Hey Juan, from my understanding, they're identical between the 8th and 9th gens
How do I know if my back shock is in right height? Correct me if I'm wrong but the height of the car ajusts on the spring, and the shock height is soft/hard settings? 🤔
Just a question why the others when adjusting the lowering of the Devorce suspension is only the spring and not the Strut, it was said in the video that when you adjust the spring, you also need to adjust the Strut
What if i have two middle numbers on the springs? Lord help me lol
When adjusting ride height in the rear, making the spring longer makes the car lower or compressing it shorter makes the car lower? Hope that makes sense
This is the coilover / control arm setup for dummies. Excellently done.
221 from heaven a nice haircut fade next couple seconds you're all shaggy😅
How much would it cost to do coil overs and alignment on a 2017 civic hatch? Any rough idea
@5:20 is the spring adjustment always on top or can it be place on the bottom lower control arm?
I have not seen a better in-depth explanation for Coilover setup thanks bro
The bottom collar on the rear spring spins the whole thing and not just the collar, please help.
Thank you for share this with us 😎 ! In my personal opinion i really prefer the old school suspension that Honda what did use before coilovers front and rear without the spring in the rear easy and simple !
You and me both! It's insane how many different rear suspension designs there are, and how some are easier to work on than others! Ideally, multilink rear would be nice for these cars, especially since it would eliminate the heavy steel trailing arm, but oh well lol
Man this is amazing like always just seeing these videos really help me out and understand more about my car sounds kinda selfish but I like knowing I have have a guide from someone else good work man🔥
Thanks Brian! I appreciate it 👍 I'm happy to help! Oh I know exactly what you mean, that's not selfish at all.
Amico,nn capisco la tua lingua, ma o capito moto e cose su come installare i miei ammortizzatori BC racing.... ciao
Nice video , I have the same coilover on a x5, but the rear tires are robbing with the fender when im driving and go over highway imperfections, should I raise the rear or should i just put more pressure to avoid too much damper in the rear? Thanks
Honestly, I'd just ditch the way that so many people and manufacturers get wrong. What I mean is that......
A) The lower spring perch is actually what should be adjusted for ride height.
B) The lonesome lower locking collar is actually what should be adjusted to dial in shock travel.
C) You are likely rubbing because you haven't set your shock height to hit your bump stops before your tire rubs. There are some really good videos that cover how to do this.
I'm still learning and far from an expert but I can tell that well over half the content on here on coilovers is incorrect. Mike Kojima with MotoIQ is phenomenal and explains a really easy way to adjust your dampers once you dial in your ride height. Also, depending on your desired ride height you may have to switch to different springs.
I should mention that you of course can shorten your shock length but know that I'm doing so you are sacrificing shock travel. Hope this helps you in some way. I've been trying to dial in my godspeed/bracing/custom coilovers for the past 1.5 years with limited info/resources for my car. Good gods has it been an adventure and will eventually post my experiences on a couple forums in the future.
Thank you so much for the clear in depth explanation 👏🏽
Happy to hear you enjoyed it! Feel free to to share the video 👊
Should I tighten by hand till I can't tighten it no more with my hands on the spring. Or just till the spring stops moving.
whats up bro? i have question , everytime i adjust the ride height. do i need an alignment? thanks
How do you adjust preload on a divorced setup when the shock length isn’t adjustable?
