FYI you are NOT increasing spring rate or stiffness with increased preload. You are just reducing droop travel. And you want to measure preload by measuring the spring, not the shock body. Also, with zero preload, a new spring will settle a bit after driving so you will end up with a lose spring and will have to adjust again and add some preload. This is why most coilover manufacturers recommend a very small amount of preload when installed new. Hopefully people read this for the correct info!
Appreciate the humble response to my note, sorry if I came across harsh! You're car is great, just want to be sure people have the correct info, suspension is super important!
It also can very by spring type. I've seen what he says be true by one brand but different by another. Not all springs are created equal haha. But for my car I actually had to make the rear right be a quarter in longer to have a qual ride height. But my car is fwd with a panhard and solid rear beam so there is a leverage difference. Left to right. But just like you learning as you go.
I just put some coilovers on my civic, how can i get the front ones set for less bounce so i dont pancake my oil pan on every big dip in the road thanks
Spring rate only changes if you have a progressive spring not a linear spring. So adding 4mm of preload to the spring doesn't change that in your case. BC does that for sag or settling of the coil so that you dont lose preload and have it loose and rattling. Pretty standard setup.
Video a little bid old, but tell me if I am right. For example I have bc racing coils aaaand for example my overall front spring lenght is 200mm. Bc racing says that preload is 4mm, after preload compressed spring lenght should be 196mm?
The- preload is gone when lowering the car down on ground with them mounted. So "pre-load" adjustment would for final be to stop the down movement before the car slams the tarmac on speed bump. You can really preload those coilovers when you have the height adjustment on lower end. But the preload must be so tight that car stands on the ground with fully expanded shocks. It will get uncomfort dince the car can’t move upwards. And downwards are restricted much. On mine i have notised that rear coulovers are adjusted so it can’t touch the ground with load. Better with springs banging than bashing the car in the ground(as ling as upper shock mount handle it. But i have noticed some range problem in uneven roads. So i are going to check if there is more margin downwards to the ground. If it is already close enough i let it be that way. Driving normally might cause 1-3 bashes( bottoming) a year up in the shock mount. But 180-200kph can raise consentration levels and conserns on uneven roads. There should have been a stopper with a coenic shape absorbing the bottoming. I am going tho compare the measurements between the right and left side on my rear. Because its on the left side it bottoming in the spring. So im going to match the right side. So there are some more things to think about with those coilovers . But its better than groundslamming. Cars might have different groundclearance with same coiloveradjustments. Design/weight differences😊👍🏻
Thank you for this video. I think I'd use a high precision ruler instead of tape measure which is not accurate for precise measurements especially if we need only a few mm.
In my opinion ,this is the best best system of coilover sunspension.The lower and the spring "hardness" is is absolute independently of each other , and really i can't understand why this perfect system ,we don't see on big serrious brands ,and only china brands.
With Swift springs, you are NOT increasing spring rate when you compress the spring, that is literally the benefit of Swift, as they are not a progressive spring, they are a linear spring.
does this also work on used coil overs? my friend gave me his set after having them for 3k+ miles and I noticed the spring were moving freely up and down on all fours, should I also adjust it or just leave it alone?
Good video buddy thanks learning for I will purchase first set of coils godspeed. Now it says for 10mm do I have to do 10mm or can I do it at 0 or should I do like 5 . Thanks buddy.
You are not increasing the spring rate with linear springs. Adding preload reduces the droop when the car is lowered on the springs effectively making the car higher for height.
I prefer 5mm peload because if that collar ever becomes loose at 0 preload the spring will become loose...5mm preload gives some play if the collar becomes loose and it unloosens spring....
Don’t mean to sound elitist or anything. Been doing a lot of research and learning, and what most coilover companies tell you about adjusting ride height is wrong. Ride height should be adjusted via the spring perch. If you find you spring is loose get a helper spring. Preload doesn’t matter. The bottom mount should be adjusted to give maximum shock stroke without your tire hitting any part of your fender wells. You can measure this by removing the spring and just installing your shock and tire. There’s a reason big a lot of companies don’t have adjustable bottom mounts on their coilovers. KW, Penske, H&R, and a lot of other true racing brands don’t have adjustable bottom mounts. Research and demand all these coilover companies give us proper suspension set ups. They’re just trying to make a quick buck out of us and your car may or may not handle better.
Not entirely correct. I have found that adjusting that way as well also decreases shock travel. The bottom line over adjusting any coilover will take it outside of what its designed for. The twin tube designs that those companies are using(Penske or Moton) have a longer stroke. Thus unlike monotube/inverted monotube they have more travel that can be given up. For an inverted monotube design I would say its better to do adjustments at the base. Not to mention you can also do some adjust via preload as well. That's why you can do both.
I have a 2001 Honda Accord with a Spyder package. I have learned the proper way to adjust the coils now. I watched a video and the idiot said you adjust the height with the coils. Wrong bottomed out on some bumps. I will be fixing that. I am also 71 years young.
i install the cloilover on my nissan it handling good the only problem is that every time i drive to a road uneven the car jumps and move my body jumps 2 or 3 time, is there something else to do, or it may need to set the preload thanks. good video man
Before there install you should have set the preload in the car that way u can be sure it’s same left to right. And if u said u did an alignment at the shop they should have done the rear toe to get it within specs
@@BulletsGarage Thanks I just got my new BC BR coilovers wasn’t to sure if they come preset with preload most of the install video showed people messing with preload.
you don't understand what preload is for. Each shock is valved with a preset spring rate, as you order the shock set for your specific car. Preload is for the weight of the car. Different front and rear.
How do you ajust it then when your coilovers are from japan and the instructions are in Kanji bruh? Mine are set without any preload and I just dont drive my car. Stiffness is at 28 on 32 and it still drives like a cloud, tein flex z acura tsx 2010

Does the shock have to be fully extended before hand tightening the ring?

Definitely adjust it
What does the preload do? If not dampening available, can the pre load AFFECT the ride?
Yea if u add more preload it will be a firmer ride
So how can I stop the bounce factor
What is your set up??
@@BulletsGarage ,I just had rear, Maxpeeding, coil overs on my ss commodore wagon,and it’s making me sea sick
For that specific car I am not sure what spring break would work best. Check on the forum see what people say
U need a right amount of SAG. Each spring can be preloaded to certain extent above which u should change spring rate to higher one.
Got ya thank you.
Good video buddy thanks learning for I will purchase first set of coils godspeed. Now it says for 10mm do I have to do 10mm or can I do it at 0 or should I do like 5 . Thanks buddy.
How much preload need for improve cornering?my rear spring rate is 4k
Only 4k spring rate? What car? What coil set up
@@BulletsGarage im from malaysia and use proton satria neo..high low softhard bodyshift..front spring is 8k and rear 4k
Bro just throw this whole video away🤣
does RACELAND make coilovers for GSF?
I don’t think so

I prefer 5mm peload because if that collar ever becomes loose at 0 preload the spring will become loose...5mm preload gives some play if the collar becomes loose and it unloosens spring....
So….. Depending on your vehicle, 4mm “preload” is going to be different with every car..surely the GVM plays a part in this calculation.?

Did U get an alignment done???
Bullets Garage. I did but it still the same abd i fill that issue more on the rear, the car is rwd
Did u set preload before the install? Did the alignment shop adjust your rear toe? That’s what would cause it to feel jumpy
Bullets Garage that something i haven't done yet i will need to check preload and rear toe, hopefully the jumpy goes away. Thanks man 👊

Thank you very much, I subscribed a long time ago, I may start doing mods if I acquire the car
Let me know what happens
Truly thanks
Why don't i get this????
Idk
Zero preload means more body roll on turns? So If I want very little body roll I need to increase the preload to the max!

Thank you. Helped me out. I had messed with the spring adjustment thinking it was same as the actual height adjustment
Glad this helps man
Some coils are a bit longer then others. Especially in the rear of most cars.
True that
Dont listen to this guy
You don’t know what you are talking about.
You preloaded it at least 2mm by hand and compressing a spring does not change stiffness.
