- Stock shock absorbers don't allow for altering ride height - that's where coilovers come in. How to adjust coilovers. How to lower your car. This video shows how to raise or lower your car using coilovers. It is important to note that altering your ride height will change your suspension geometry, and should be followed up with a wheel alignment.

One final recommended step. If you take your car to get an alignment, ask to have the car corner balanced. If they look at you like you are stupid, find a shop that will corner balance your car and corner balance it CORRECTLY so there is no wedge in the car (the sum of your right front and left rear is the same as the sum of your left front and right rear) when you are in the car. This ensures that your car has the same handling both right and left. Just adjusting the ride height alone will not corner balance the car and can actually upset that balance and can create a funky handling ride.
Can I do corner balance even I don have adjustable drop links?
Bro real men don’t get an alignment
@@awwbubba3071 😅
Very important.. I’m dealing with that right now
A wedge in my tire to say the least
If you don't have something to measure the gap, you can also count how many threads are exposed.
I like your style
good thinking bat man
I just measure the gap in between with some piece of paper and make sure both sides are even.
Can i borrow and extra hand to count ?
Very happy to hear it, thanks and thank you for watching!
Spring stiffness will not change, and I'm not changing the overall length of the spring (known as adjusting pre-load).
This was my main question. If you put the coilover all the way topside or bottom it out.. The spring will feel exactly the same???
So far so good, I definitely like them. They are stiff so they won't compress as much with weight in the car, but that said it is a bit rough over certain bumps and such. But yeah I'd say worth it, I've looked at others and the spring rates seem to be fairly similar across the line.
Yo
Holy crap! Just stumbled on an OG video from 9 years ago. Bet you didn't expect your videos to take off like they did but i still learned something from this vid.. had to double check my brain on the right way to raise or lower coilovers..
Yonaka supplied me with the coilovers; I haven't looked in to other brands much. They're definitely stiffer, but body roll is also reduced a good amount.
They gave you the coilovers and you didn't review them?
You can get more adjustments from some more expensive coilovers on top of height adjustment (or preload). But they are mainly use for 80% track and 20% road.
Eg. compression and rebound adjustment for the shocks.
There are also some coilovers that you can adjust high speed compression and rebound, and low speed compression and rebound.
Great video, I used this video to help me adjust my coilovers.
Also every coilover is different, just because he set his at 6.5 inches doesn't mean you should set yours to 6.5 inches too. The coilovers on my Toyota Celica was exactly the same inches as the wheel gap, where 4 inches on the coilovers (bottom of bottom-ring to top of top-ring) was exactly 4 inches on the wheel gap (fender to tire).
Question for you: I've heard pretty often that you should -not- adjust the lower ring (not the lower shock collar, but the lower one by the spring perch) as that will mess with the preload, on coilovers with threaded shock bodies. So, I'm slightly confused.
Well, it's best to eliminate camber for street use. It will cause uneven tire wear, though I've heard poor toe is worse than a little camber. I'm planning to get adjustable camber arms to compensate.
You don't actually have to keep periodically checking the height. You can just take the lowest lock ring at the bottom of the threads, and bring it up to where the gap between that and the top adjusting rings is the placement you want it at, then keep adjusting down until you get the lower lock ring at the bottom again. Then measure and adjust slightly if needed.
that’s what i thought he WAS doing😭😭
I read you're not supposed to adjust the bottom ring. I'm not sure if that's a universal rule. But I never touched mine.
Perhaps, or some dry lubricant. Grease would likely get a lot of dirt/debris on it. They make special stuff for shock threads as well.
For all those confused on how this specific coilover system works. The 1st gold ring right under the spring itself is to set the pre-load... but only until after you set it appropriately and use the 2nd (middle) gold ring to lock it in position can you use that same 1st ring to adjust the height. This specific coilover systems spring is independent from the top mount so it can move up and down without affecting the pre-load.
Lies
@@babyboynene literally truth.
Yah basically using the "jammed" nuts to spin the entire shock body into the sleeve
It is pretty awesome indeed!
By lowering mine it increased negative camber and altered the toe. I don't yet have adjustable camber arms so I just had the toe adjusted.
Hi Jason, I didn't see it mentioned in this video, but at what point do you need to add adjustable endlinks when lowering a vehicle?
Nice video! Would recommend these coilovers? How have they held up since you installed them?
Yes, excessive negative camber would cause the insides of the tire to wear quicker, while positive camber would of course cause the opposite.
Question: How do you measure the length/height accurately? Any specific tools needed?
Perfectly explained thank you!
Thank You Brotha,straight and to the point 🙂🙂🙂. Greatly appreciate this info
The actual adjustments aren't that difficult, but I don't own the expensive laser level tool which is used to find out where your alignment is at, so I probably won't have videos on this anytime soon.
Awesome vid man! I'm actually about to adjust my coil overs on my integer as well.
It must be nice having a company like Yonaka GIVING you coilovers!
how does one go about learning what ride height/ other coilover adjustments are optimal for what situations?
Thank you! I've owned a car with coilovers before but it had it before I got it so never messed with them. I'm installing new coilovers on my car tomorrow. Glad I found this video, didn't quit understand it but now i realize it's just common sense for up and down 😂😂 thanks bro!
Me too I think your videos are brilliant, and you come across really good on TV .
Great video and easy to understand, just a clarification please, in order to raise the vehicle do you make sure that the top 2 collars are well tighten together and rotate the lower collar (of the 2 collars together) counter clockwise looking from the top, should the shaft rotate (the screwed long portion) with it too because when I did that, the shaft did not turn with the collar, what did I do incorrectly? Perhaps the 2 collars were not locked together tight enough?
Terry Tak did you back the bottom, smaller ring away from the lower mount a little?
This is why I like this channel so much. Most of the other videos on RUclips are done by shitty 20 year olds who make their videos pointlessly 12 minutes long to help with monetization. You made a quick, easy video with all the explanation anybody would want or need.
Correct me if Im wrong but I thought the locking nut/ring at the very bottom had to be loosed then rotate the whole spring assembly to adjust ride height?
thx u for the video, helpful. how do u adjust the rears though? should the height be the same as the front when you measure from the wheel arch of the fender to your tire in the rear?
This could get expensive with the alingments depending on how much you raise and lower your car . I have a 2004 civic ex , I'm considering getting some coilovers, but not sure what brand to go with , any suggestions?
i dont have the bottom locknut, i just have the preload spring 2 locknuts. This means its non height adjustable?
Didn't you have to unscrew the bottom first to make the adjustments to the height? Then retighten the bottom to lock, right?
To lower it yes. To raise it technically you wouldn't have to because it's going to move up as the assembly moves up. You still should though just to make it easier on your hands. 2-3 adjustment sessions will leave your palms sore lol
I think he was talking about the bottom ring that is locking the top ring, not the ring locking the height. So I believe to answer his question, is no, those 2 rings are to adjust the spring preload.
I can do mine pretty easily with the wheels on. It helps to steer the front wheels to the side to use the C spanner. It's going to depend on your car and dexterity I guess. Lubrication helps as you can spin the shock by hand rather than having to turn it with the spring perches and spanner.
please make a dampening/preload video. or help me out and explain how to adjust them and what I would need to do. my car is crazy stiff and I am not sure if I need to adjust both and or how much I should be adjusting each of them. (I purchased the car like this).
Hi, I adjusted my coilovers, all measurements from bottom of the ring to the other ring are all equal. Drove it for miles, but I found out the wheel gap is not equal? Is it normal?
Thanks so much man, I wanted to lift my car a bit since it has sport extra kits all round, asked macanics to work for me on that, and everyone like no the only option is to remove kits and drive, but watched ur vid today morning and I already did adjustment it wasnt hard really, thanks so much for tht
Ok, now I know how, to adjust my dampeners. But, I'd really like to know 'why'. I mean will I adjust them until I'm happy with the ride and handling?
If so then I'm going to spend a lot of money on alignments as I go through a trial and error process. Not to mention that I'll probably want to adjust differently for different tracks.
Are there manufacturer settings that are geared toward certain track types?
What if i accidentally spun the lower ring to the left? Would spinning the wrong way ruin the preload?
Thanks
Do you need adjustable upper control arms when adjusting ride height? you would think it would change the camber if you didn't have that adjustability
will these maxpeeding coilovers keep an integra at stock height or slightly lower? I dont want a lowrider
Thanks simple & straight to the point!
Unfortunately not! I don't have the measuring tool, and they're quite expensive.
I just bought a 98 Honda Prelude. The front is lower then the back and its difficult to drive into parking lots and out, dips and bumps etc. I want to adjust my ride height and this seems like a pretty simple video to follow. I guess my question is , if I remove my wheel I could probably find a similar set up and follow these instructions?
With these coil over adjusting springs over time does these lower on there own? And then you have to adjust them over and over ? Or is it just set it and forget it?
Check out my videos on camber, caster, toe, and steering axis inclination. These are different variables (some of which are not adjustable) which can be used to alter alignment. Most shops will alter toe, and some will alter camber (if adjustable). To be sure it's done right, ask for a print-off of the alignment before and after, and ask what the OEM spec for the vehicle is. If they can't tell you (or provide this), pick a different shop!
Can we see a pic of the final result? I wanna see how good it looks!
Question, do all the gap inches between the tires have to be the same or close to the same height like left front and left back to be symmetrical or is it irrelevant
if youre asking if the fronts can be a different height than the back, then yes you can have them different. if the front is lower than the back its called rake, too much rake is a bad look though
Is it really necessary to align the wheels everytime i change the height? Bec im planning to get coilovers so that i can lower it on track days n lift for daily driving.
Does camber affect tire wear, like excessive camber?
What about weight distribution? Does this need to be taken into account when installing coil overs or adjusting height?
I’m having trouble . Today I tried to install my coilovers but has I was adjusting them to be lowered, the spring would stop going down and idk if I’m right but maybe that’s the lowest? But it makes my car sit high as a kite.
Did you have to roll the fenders ? Or where you able to drive without any scraping of the tire against the fender?
Thank you for uploading this I was confused my buddy tried explaining it but u just helped mea lot lol mine our coming in Thursday
You're very welcome, thanks for watching!
lol 3 more days too bad ohios winter probably wont be over for another month or two then theeyll be on
Do I get wheel alignment right after adjusting it or should I wait a couple of days?
Do you have to raise that bottom ring before you start turning the top one to the left?
I like your videos bro. Your the only one making videos that I layman like me can understand.
Keep up the good work brother 😀
Thanks Man! Ordering mine after I type this...
hi. If I adjust the rear coilovers in 1inch, is it the same in the front?
What does the pre load of the spring measure .from the top orange to botom orange lock nut what does it measure from factory . Had the car adjusted an they mest with that in sted of lowering it
I see you are slowly showing off the ride. Can't wait until we get a acceleration video and a demonstration on aftermarket performance clutch.
Thank you for your video. Would that be the samething on a 2004 Mazda 6?
Did you adjust/lower the bottom piece of the coils or just the rings?
Yes, indeed. I mention adjustable damping in my coilovers video which is common on more expensive coils.
Does the upper wishbone get any closer to the wheel when lowering the ride height?
By altering the height of the coil- over spring, does it affect the spring stiffness in any way?
Theoretically, no, as it is a linear spring so the rate is constant with deflection.
I thought you used the bottom adjusting ring to raise/lower? The top two would mess with the spring rate wouldn't they?
Would it be a good idea to put some anti seize on the threads to stop the adjuster rings from sticking?
Wait, didn't you say in the last video that the lower part that gets bolted on is what changes the ride height without affecting the suspension geometry? So what you did affected the geometry of the suspension, correct?
Rookie question, you have the bottom ring all the way down then the next camera change you have the bottom ring up? I didn’t see you move the bottom ring, so I have to turn the bottom ring up the desired amount I want it lowered? THEN turn the top ring to the left until the bottom ring is sitting flat then tighten the bottom ring?
Thank you for posting a clear explanation. Nobody else on RUclips knows how to make a decent video...
so i have to loosen the bottom one first? then i can spin the 2nd ring to raise rhe car? i tried raising with the 2nd ring but it felt tivht and i wasnt sure if i was doin it right because it was tight
Very nice video, straight to the point
great video simple straight to the point.
So the ratio of the coil adjustment to how much it actually lowers the car isn't direct? I.E to lower it 2", you can't just change the coil adjustment 2 inches? If not, with your experience do you know what the coil/wheel gap ratio is?
this is adjusting preload is it not ? I'm being told to loosen the bottom spindle, then to turn the whole coil itself.
i just installed hks coilovers w/ adjustable height and damping. I have it on the stiffest setting but the ride is really bouncy :( it oscillates and takes a while to settle. What do I do to fix this?? adjust pre-load? what is the purpose of pre-load? How do you know how much to pre-load it?? is the spring supposed to be able to spin once its preloaded? I can't find any decent answers
could you define wheel alignment? like what it is actually? and when you get it, how do you understand it's been done right? thanks
No damping adjustment. They feel stiff, but not bouncy. Vibrations seems to be dampened out well.
What was the ratio between how much you adjusted the coilover length to how much the car was lowered?
NICE... A teggy always looks great lowered! :) I hope we get a video on the track explaining how to race :P
hey does this goes for all coilver setup? mines looks kinda like yours but for a s13 from Powertrix. I just don't want to mess up just making sure
soild explanation! thank you!!
do i tighten my bottom ring all the way even when that little spring/gasket thing is under it?
Okay So quick question, i have a 2006 civic si, i bought godspeed mono ss coilovers for it, installed them and could never get the bounce to go away, could it just be improper setup or that the spring rate on the aftermarket springs was too high?
Im curious as well. I have an 07 EX and hate the factory ride. Want to know how to dial out the "bounce " if i encounter it. Thinking about Tein myself
Christian Anderson cheap coils. Try adjusting the dampening to a stiffer setting see if that helps. I put on Megan racing coils and they bounce too. Going to settle for air suspension I want that smooth ride
So are you using the two upper rings to turn the whole body of the shock? As long as the rings do not separate from each other, the spring preload will not be changed correct?
@Engineering Explained - I have seen some reputable sources say adjusting ride height from the lower collar is incorrect. They say to make ride height adjustments at the lower spring perch. This makes no sense to me and intuitively I adjust ride height as you did in the video. This method does not disturb bump/droop distribution like spring adjustment would. Any comment on that?
Question I just got my coil overs and they are threaded all the way to the bottom on the lower seat so I leave it like that and just adjust the coil only ?
I'm interested in the yonakas for my car are they worth it? I usually have a full car so I wouldn't like them to not hold an rub on my tires. My stock suspension does that and its so high so I need something stiffer and longer lasting
I just bought Function and Form Type one it's my very first coilovers I'm waiting for it to arrive in the mail the dampening is pre set by the manufacturer it's only a ride height adjustable coilovers which is what I need I thought you aren't supposed to touch the upper perch only the lower perch so to lower the ride height I would turn it to the left or to the right could someone help me out
if you raise the coilover really high will it pop out? , i want my car stock height.
I dont want to sound rude but the explanation was a bit confusing. Like somebody asked, the way you worked looks like you were modifying the spring load by turning the orange nuts. What actualy you did was turn all the upper part of the coilover and introduced it in the base part of the coilover.
I think you meant preload. Spring load is how much weight the spring can bear at a certain distance. That is already designed into the spring that you select. You can't adjust that after the fact.
al rod Yes you can adjust preload. If you picked up for day a used set of
Coilovers your supposed to set the preload if it has any play in the springs . You can adjust that all the time lol
This comment is very important.
He actually loosen the 3rd collar to adjust the height of the suspensions even though he spun it from the orange ones he wasnt really messing around with the preloads
@@yogipangnanouvong388 we know. He was getting the right effect. But the correct way is to spin it from the bottom to avoid messing with the preload on accident. You loosed the lower jam nut/collar then spin the bottom of the strut.
Doesn't doing this reduce the spring's stiffness by decompressing it? And can that lead to a higher risk of the car's undercarriage hitting the ground, because you both lowered the car and reduced the spring stiffness?
Just curious since your coil overs have the threaded sleeve at the base to adjust the ride height why did you adjust the spring to change your height, is there any benefit or loss to doing it this way?
I left the spring pre-load as is, and simply adjusted the length of the strut (spring did not move).
Hey thanks for the response i appreciate it. My apologies I just re-watched the video and noticed that you never separated the two jam nuts and by keeping them together it made the whole sleeve turn. I havent had to adjust mine while still on the car so i didnt consider doing it that way but good to know thank you. One more question for you if you dont mind. I have the skunk2 pro s 2 on my eg hatch and i havent been able to find any definite answers even from skunk2 on where to start with the preload. Do you have any suggestions?
Would that alter the spring rate or stiffness of the spring after lowering it?
Im bought K sport suspension for my Honda Crosstour it can adjust about 2.5 cm lowered from my stock but when i bring to the shop and they done for car, it’s lowered than that I expect and the problem if i hit the bump sounds like cracking,, sounds like my springs at the rear is to much compressed,, im just asking is it normal or will be bad to my car,, i need ur help and pls comments thank u
explain how to adjust 3 way adjustable coilovers please, like the high speed compression and low speed compression part, there is nothing online that teaches it
Thanks..you answered all of my questions.
