Rev9 Coilovers - Height & Shock Dampening Adjustment Front/Rear How-To
ฝัง
- เผยแพร่เมื่อ 4 ก.พ. 2020
- A lot of people are confused on how to adjust Rev9 coilovers height and dampening. The dampening is more straight forward, but the height is not. Some coilovers have you adjust the height by compressing the spring, but with Rev9, the height is controlled by the lower mount.
I wanted to take some time to make this video since we had the coilovers off of a customer's car and it was the perfect opportunity to explain the adjustability on these. Check out the video and let us know if you have any questions.

what if I raised my rears but the car still sits lower than i want? 2008 Acura Tsx.
side note, i cant go higher without having the threads fall out of the black part
Would these be ok for a daily driver that’s a weekend touge chaser?
so, according to your video WE HAVE TO take out coilovers first before Adjustment ??
If not, How do we adjust when the coilovers installed ??
Thank you for sharing, too many people *cough (donut media) tell you to stay away from cheap coils like these because they don't know how to properly adjust them, too many big egos in the car community lol but I digress. Much love brother!
Chefs kiss 🤌 great video. Looking at getting these for my speed3 sometime next year, finally starting to build it up got wheels and need to do suspention next.
Thanks for the video! Helped me figure out exactly how to adjust my rev9s on my tsx
had these installed on my girls 2015 tc so far so good just gotta adjust the height in the rear
How difficult is it to properly adjust the height and level the car out with these? My girlfriend actually bought me a set of these for my birthday. Very excited to see how they’ll perform.
Your the best that’s how I adjusted yesterday it ride great not bouncing very good suspension for their prices
This saved me time!!!! Shops did it once n felt like shit i did it while watching this . Smooth ride.!!
thank you! was looking to buying these for my tucson
Im doing this for the first time this weekend. I’m so terrified. I’m trying to take mental notes watching all these videos
Thanks for sharing I'm sure I'm gonna be ordering these for my Tc2
Excellent! Thank you!
i just put these on my 2001 corolla and i had to pull my rear fenders out to the max . i had the rear at the highest setting but still had mad scraping on my 8" rims. just fyi to those out there. i'm happy with these for sure. bang for the buck
Good to know, been looking at these for my 05 IS300....
Did you end up getting them Rob?
@@ahmedradi8661 I didnt actually. I did some more poking around on em and actually chose to go a different route (tokico orange ST struts, and stayed with stock springs)..... the struts with the stock springs added a good a pretty clean ride and carve pretty hard in the turns. Plus, with a set of cusco upper (front/rear) strut tower braces it really tightened up the suspension....
Awesome!!
Very helpful thank you
i just bought mine for my gs300 and going to make a vid installing them.
Just got my brand new rev9 adjustable coilovers about to install soon.
what is the max lowering on rev9
@@dylanmajors8392 way lower than you can physically drive
@@mrdauntl3ss nahhh im hitting my front bumper on every little bump but she still drives, kinda lol
carter schnick how do you think these would fair on a G37s? How long are expected to last
Ordered some for my 01 Lexus GS
i have the same car. how are the coils?
I sent mine back after reading a few reviews,I went with thr flex z
Just go my set now for my 93 Sentra 🤩
How have they been?
Great. No complaints
How do adjust the preload? Thanks!!
How many inches does it lower at its highest adjustment. Whats the range? 2-4 inches?
Just ordered mine for my focus ST
mine are a little short
i ordered mine for my acura tl
I’m looking for some for my ST. Honest opinion… how was the ride?
@@josemerino5048 how they holding up debating these myself.
Okay now I'm confused I have a 2013 Civic SI with rev9's divorced setup on the back. Do you adjust the height with the struts or the spring because they both have adjustments and people are saying don't touch the spring because it's the preload and other people are saying that's how you adjust the height so which is it. It makes more sense to me that the adjustment on the spring is for preload and height adjustment is on the strut. Correct?
Are these the HyperStreet ONE or 2? I don't even see threads in the pictures to adjust for the Hyperstreet ONE for my 2008 Dodge Caliber. Are these Divorced style adjustment? Also do I need Adjustable Sway bar end links?
My damper adjuster came off can I put it back on or does it need replaced?
Hi what's the length of the bump stop
I heard that you can adjust them from the top but I can be wrong
Can you do this while their on your car
They should put instructions in the box for the ones who never messed with that
Where are these made?
Thank god for this video cause nobody has shit for these coils
On my car i cant turn the bottom mount because if i do that then i cant bolt the end links back on.
Anyone know what size coilover wrench I need for these
So for divorced set up you only adjust the springs to go lower but leave the shock the same?
I am wondering about that also. I would assume you adjust the spring height to your desired ride height and then adjust the shock so that you maintain full shock travel. If the shock is too short, It'll preload the spring and if it's too tall, It'll bottom out since it's effectively shortened the travel distance of the shock.
Can't I just cut an extra inch off the threaded upper part of the rear so that I can screw it further into the bottom piece? I tried removing the rings and green spacer from the spring so that it's just sitting on the rubber piece and that big threaded bolt on the other end. Even at the lowest on the shock, it was still loose after letting the arm down. I put just one of the rings back on and now the spring is exactly snug, but no pre-load. Otherwise, I can take both rings out, and use the green spacer at the bottom of the spring (or maybe that's supossed to be at the top), and then I have 1 cm of pre-load. Honestly, I can't tell if that lowered the rear because I forgot to measure before, but the rear is a lot softer now and less bounce. I feel like, I'd need that shock to go lower though in order to get the ride height any lower, which is why I'd like to cut some off that threaded upper piece. Then, I figure I can take that green spacer and both rings off the spring assembly, and then still get some pre-load.
I'm really not understanding what you mean about the rear coilovers when you say you want the thread to be "up here" I think what you are trying to say is that you want to make sure you have enough of the threads into the lower mount but could you clarify the maximum height you can adjust to on the rears?
Correct! We've just had some customers leave one thread and then wonder why it broke... make sure to have enough thread in there so it's secure and won't break loose. Every application is different for adjustment, but when you have about an inch of thread left, you know you pretty much maxed it out
Does anyone know any good for everyday driver does anyone recommend these for 2013 Honda Civic Lx auto or keep stock coils??
Hi i got these installed on my bmw f30, the problem is the front doesn’t lower more than 1” inch. The back is perfect at 2”inches but not the front. Do you know the issue i may be having? Could it be that thee coil-overs don’t really fit a bmw?
I think you did exactly what he said not to do. Lower them spinning the bottom of the strut instead of spinning the spring
I have a question. Mine look just like the ones you have pictured. For the rear shock do I adjust it at all? I’m going to set my rear springs as high as they will go. Would I wanna do anything with the shock?
I am installing rev9 coilover on 96 bmw 328i, i seen some guys do a preload on rear before mounting the strut, how much of preload should be done for rev9 coilovers ?
how it hold up
So coilovers can adjust the height to lower it right...Can they be an replacement for ride height as well or raised the height...I'm just curious????
No, usually you drop around 1-1.5 inches
Does anyone have these for the 10th gen civic hatchback sport?
Cuánto más se puede subir antes de que se safe ?
So disappointed i got these for my bmw f30 the rears are slammed at 2 inches but the front wont drop mote than an inch, so bad
I just bought a set of these rev 9's for my 2018 accord. I don't know how low to go. what would you recommend? I want a really nice stance but I also don't want it too low. maybe a lil lower than oem.
Victoria Garcia suggest u make the tire barely kiss the fender basically eliminate wheel gap
How have these been holding up for you? Very curious, thinking bout getting these for my G37s. How’s the ride feel
@@swervv2957 put em on my g37 they pretty good
I got these on my accord abt barely a fingers width pretty nice n low stance with no rubbing. Hope this helps
It’s still confusing on maxing them out on lowering them like how do you know when it’s maxed out
When u don't see any visible threads
the stabilizer links aren’t long enough to reach from the coil over down to the stabilizer bar……..
If I maxed these out, would it bring me to stock height? Or just by design, will this lower my car no matter? I don't really want to low my car much at all, but my oem equipment are blown
No won’t. And honestly they ride like shit
Bump
Bro coilovers will lower the car
I have a 2013 bmw 328i and it’s making loud clunking noises over bumps. Does anyone have an idea why that’s happening and how to fix it?
I been using these on my 328i f30 for about 2 years now, only complaint is that the front didn’t drop as much at the rear
so essentially he was all the was low and compressed them more to get lower but ruining his preload?
How did he ruin preload?
Can I do the adjustment while it's already installed on car?
Fr!!
So i bought these for my 2015 bmw 328i Rwd. The shop installed them, the rear slammed at 2”inches but the front doesn’t lower more than 1”inch. Maybe only for my bmw? Anyways the install went well besides the height issue. But now im getting a clunking noise on the right front passenger side when i go over bumps an road dips. so theirs that.... Damping is on hard
Did you fix it? And if you did fix it, how did you do it? My bmw does the same thing and the clunking noise is hard.
@@Martian305 did u fix it?
@@Martian305 Thats my comment on a diff acc, did u fix the noise yet
so, according to your video WE HAVE TO take out coilovers first before Adjustment ??
If not, How do we adjust when the coilovers installed ??
They come off
Realizing this after ordering them lol seems to be a simple install tho i wont mind
Thats what the spanner wrench is for. You don't have to take the entire coilover off to adjust ride height
I am looking into these but do not want to go crazy. Just drop of about .5-1 inch at most. Do you recommend these?
Usually, at the highest setting, they will still be right around a 1 inch drop. If you want to go less, we do have TEIN on our site also, and depending on your car, it might drop less... the rates are on the listings on shop.redline360.com/collections/suspension?_=pf&pf_pt_product_type=Coilovers Thanks!
Redline360 I want to know if tein basis z would be good on my G37s coupe? I’m looking for stock comfort and not looking to drop much more then stock height aswell. It’s my daily car and I drive in LA roads
Can you adjust them when there on the car.?
Yes
Got these installed at a professional shop yesterday but the ride is Really bad. I wonder if they ruined the preload trying to lower it like you said on this video. Would lowering the top preload help smoothen ride quality if that's what they did? Or will It be guess work trying to re correct preload
Just take a look at how they have it adjusted and see if it looks like it should with the ride height of your car.
I made this exact mistake, lowering them using the spring ruins the ride. But then going back and doing it right will actually fix it
I'm late but this actually just happened to me, so does this mean I can't adjust the ride height and increase the height without completely taking out the suspension all the way??
For the rears, you don't lower it with the springs, you're messing with the preload again. You want to adjust the ride height on the struts. You should have noticed that being that you just stated it for the fronts.
Yeah I was trying to figure out how they came up with that.
They are two different types of suspension, there’s no preload on the rear without the cars weight on top, if you lower the spring on the rear on these, it lowers the height the car sits at, same preload as before
For the rear on my car with the rev9's I have the divorced setup and my springs are at the lowest setting but the shocks are at the tallest setting and it rides nice over no bumps, then going over bumps the car bounces lol
There is no preload for the rear springs without the weight of the car
@@miguelr1133 bro, someone already mentioned this a year ago, did you read the other comments?
Does anyone have these on a G37s 08 infiniti
How do you adjust the preload for the rears? I get it you raise or drop the rear by the springs, but what about preload?
Yea he deffintly contradicted what he said at first and your correct
You adjust the height to where you want it using the spring perch adjuster then put a jack under the lower control arm in the rear and jack it up until you get about 5
- 10 mm of preload then you adjust the rear shock bottom until the bolt hole lines up for you to bolt it to the lower control arm
Do these come with end links?
Depends on the application, if its needed it does come with it, check here: shop.redline360.com/collections/all/rev9-coilovers
How do you get rid of the bouncing of the coil over
Damping adjustment on top of coilover
So can u adjust them when they’re installed?
No u can't gotta remove bottom part and spin
@@AngelA-bd6nf y0u can loosen the bottom nut and the strut will spin freely without taking it off or messing with preload. Just make sure the entire strut is spinning
Which way to turn spring to lower it if it's already mounted in car
Are these direct swaps or do I need to do some type of modification or use oem parts?
No modification needed, just a little bit of elbow grease :)
How long does this take to ship?
a few days
Does this mean the ride height cant be adjusted while on thr car? Or is there a way to do the same thing while on the car?
You can adjust it while it's on the car, but you would need to still disconnect the lower mount so you can spin it. You can keep the top attached - makes it much easier :)
How low can you adjust this coilover in inches? 3"?
seems a lot lower they say 3inchs but i seen ppl go much lower on these
@@razaahmad9942 On my bmw f30 the rear is slammed but the front only drops an inch
Can you run these on a g35 sedan 06 ?
Yep! As long as it's RWD: shop.redline360.com/products/rev9-hyper-street-ii-coilovers-350z-g35-03-08-r9-hs2-008
Just installed on mine.. I had to to play with the damping.. but overall a nice shock..
What is the best dampening ? Any suggestions?
Start on the soft side. You're going to have different settings in the front compared to the rear because of there being more weight in the front. You're front settings also may slightly differ for it to feel even since the front drivers side is the heaviest corner of the car. It'll probably take you a couple days atleast to get it right where you want it.
Can you do this while there mounted??
You can, but you would need to undo the lower mount from the control arm.
you can twist the silver part when the thread with your hands is but if its too low then you cant since theres less room to grip it
@@Redline360 are the godspeeds worth the extra 200 to 300 I'm on yall website now it's hard to tell the difference
you can always adjust the ride height with the coilovers installed, you just twist the second ring (not the first one which is preload)
@@Mikey-kw7rj he just told you in the video not to do that. stop making up dumb shit when its locked into the other ring so it will actually effect preload
How much of a thread should i leave when i adjust it so i can raise the car?
He says in video😊
If the ride height is in the spring then what you just guess with the strut....compress the hell out of the spring so its not slammed then just hope the hight and preload is good because if I go by what everyone else says online I need like 3 more inches of thread on the back strut...because this video shows nothing on the preload on rev9 with the divorce setup kinda bs
Springs adjust the rear height not the shock
how did you put the sway bar link again?
Yea am sure I just ordered mine on amazon and I have a 07 sedan
The stiffness knob is no where near that smooth to turn. I have to use a plumber wrench just to adjust the stiffness
Mine was actually fairly easy to turn. Its possible you just got a dud.
i’m maxed out in the front but i still need to go lower what could i do? the rears are slammed but the front is has about an inch gap…. can i tighten the preload to go another inch up? It’s kind of frustrating, i have hyper street 2’s on my bmw f30
Get Shorter springs in the front
Initially that’s how you measure it, then after it’s been installed you can lower or raise the height by spinning the collar, not the lower portion of the body. So you’re practically saying that the whole coilover has to come out if you want to raise it or lower it......unpractical.
nah if you loosen the lowest lock collar, the whole strut will spin to be lowered. I've had them on my car for 2 months now and have played with ride height a lot and haven't had a single problem adjusting them on the car.
@@carterschnick2556 even if the sway bar link is connected?
@@hernanmurillo8925 the silver part with the spring spins freely. Just grab the spring and spin it which ever direction you need it.
@@Atrociousa3 the spring & the silver body??
yea
Does it matter if the rings are loose while the car is driving
Yes of course
How would you go about adjusting these on the car then?
Easy, you loosen the bottom one and move the second ring on top to the left to lower and right for higher. Just dont mess with the first ring AT ALL!
Same question I had
@@sniper2606 don’t you move the first ring to lower and then 2nd ring to raise it? (After loosening the bottom nut of course)
How much do these coils drop? I was hearing only 1 inch, ur website says 1-3 inches. I just ordered them
its 1” if you do it this way, its 3” if you ruin the spring load. I dropped mine all the way and still didnt get the ride height I was looking for for my 97 miata. Kinda upsetting.
i dropped my wrx about 2 /12 inches and it still can go further a bit so i think 3 for sure
and i didnt touch the preload
@@Mikey-kw7rj does your wrx ride like crap now?
My altima dropped about 5-6 inches, tucked the entire while the car was still jacked in the air
so what your saying is, if I do adjust the preload to go lower, it will go lower? could care less about ride quality cause they were $500, I wanna be dat slammed boi at the meet, not the dude with tire gap and "good" ride quality.
It will make a lot of noise and possibly blow the shocks... will also void warranty... not recommended.
Redline360 how do u think these would fair in a G37s infiniti? I’m just looking for oem match in comfort and reliability for a budget price?
You sound like me 😂👍🏽
What if I want it tall
You can simply extend it out as far as possible (with leaving enough thread that's safe).
get a lift kit
I’m maxed out dropped in my rear coils mk7 gti and it only dropped a little less than in inch. Not good coil overs
you fucked up
you goofed
Just installed mine thought you could do it on the car... that sucks
I would love to see it done on the car
Oof that probably didnt end well
Those dont look like progressive rate springs.... adjusting the ride height with the bottom doesn't let you set the bumb stops. Meaning that the car could hit fenders. I have seen other vids were ride height is adjusted in the spring....
The Expert Noob Hobbyist Doucet damn so then they gotta take them off every time to adjust?....
What makes you think that? Almost every manufacturer of coilovers uses progressive rate springs.
Would of been more helpful if they were already installed on the car
Great job on the coilovers and good advice. I installed these coilovers and I love them. I did a video on my channel of the install and will be making a review video soon, I've already started shooting the raw footage. th-cam.com/video/saGIONcaPTs/w-d-xo.html
For the height adjustment method... How do you do that with them INSTALLED??!!!! THIS IS RETARDED
Rev9 poor quality.
steet driven on a accord for a year, didnt even tough the track.
front right strut already squaling and for some reason, my wheel is dirty on reg basis (no, my brake line a clean and calipers are clean)
This a poor quality ebay struts.
side note: their accord kit, is garbage. they sell on ebay for 1.5 to 2.5 drop..
i was running alread! out of thread in the rear.. at 3in drop.
and yes, I have watched the video and know what it takes,
rev9 is garbage.
I need coil overs for my f30 bmw should i skip these and go with race land coil overs?
Jeovany 1996 naw those are garbage get bc it’s expensive but perfect. do it right or twice
Wish I would’ve seen this exact comment before I installed rev9 on my Accord. Topped out the rear coil overs and still have less than a finger gap between tire and fender….
