- Visit us at www.gtchannel.com for more content! Setting your ride height is just the start when you switch to coilovers. The real beauty of using KW DDC coilovers for us was in being able to lower the car and maintain the OEM corner balance. KW and other coilovers also let you improve the corner balance or weight distribution of your car if your car doesn't already have a good set up from the factory.

Technik and GTChannel show you how to set up the KW Suspension DDC using our project BMW E92 M3. We changed our wheels and tires to a square set up and in doing so raised the front ride height. This changed the handling characteristics. By putting on the DDC coilovers we were able to adjust the ride height and more importantly regain the stock corner weights despite the taller front tires.
Robert Choo lends us his expertise and garage to do the adjustments.

This was the FIRST video that went in DETAIL on how to do the coils....adjustments and all!! Which is what I was looking for. GREAT JOB!!!
Most people only care for the lowering and automatically think it will handle better, but in reality they just ruin their geometry...Very good video!
Nice to see someone actually care about weight balancing, CoG, setting up for load transfer, etc. Often you see guys just going for nothing else but aesthetics, and in the process they (often unknowingly) ruin the geometry and handling of the car.
Worth mentioning that when doing corner weights the droplinks/end links should be removed. Then once corner weights are set they should be replaced with adjustable drop links. This ensures there is no pre load in anti roll bars 👍🏻
So what happens after you have corner weighted and then reattach the drop links ?
@@jamsstar2010 if you corner weight it then re-attach the the oem non adjustable droplinks the Arb will be under a constant preload. Because the coilovers will be at different heights.
With adjustable droplinks you can adjust the length of them separately to match the different heights of coilovers left and right.
me 3 years ago Thanks you for this info
@@JamesWilson-du4xt no probz
This actually helped a lot, I think I have a good idea on how to do it because of this video
It's not required but to get the most out of coilovers it's suggested. They're not cheap (over a 1000) but you can sometimes rent them and shops offer corner balancing services.
Just bought these, having them installed at a shop though. Can't wait to see how she rides after it's all set up!!
GtChannel never fails to please.
Great video. Nice to have a friend who can help out with setups like these.
Informative vid :) Big thumbs up
JAVIER GUTIERREZ, Rob is in SoCal. There are a lot of shops that will do corner balancing. Look up BMW race prep shops or most motorsport prep shops.
Missed just one minor, yet important detail. Check you tire pressure first of all.
20mm in the rear is perfect. That’s what most companies recommend. People who just try to close the gap are ruining their suspension geometry. Thanks for the video. I was curious about the process of corner balancing.
Man that guy is really good at what he do...fantastic
Very educational , in explaining the purpose for coilovers.... frosty . ... COOL
nice!! keep it going with more videos :D
Really good quality video.
NICE!! Great video. The fact that so many kids lower their cars and dont understand what their really doing to it. Then wonder why they wipe out and crash. Even a lot of shops dont do this, lot of half assed people out there.
Can't wait to buy a kit for my 94 w124!
If straight line speed were our goal then yes. I (Brian) wanted a car with some luxury than can also handle well off and on the track. The Shelby is fast but it's not quiet or remotely comfortable. The M3 is my daily driver and it makes my commute super cushy and yet I can still go drive the canyons and have a blast.
Great info!
good job man!!
beautiful garage
With the button in the car between three presets. Or for more fine adjustment you purchase the WiFi module and adjust it with an iOS app.
Did you undo the swaybar links. We do when we corner are race cars it make a big difference in corner weights I've seen 400lb difference. Cause the suspension binds.
What do you guys charge for an alignment and corner balance? Or what does this procedure usually run for?
if I raise the coilover on one wheel do I have to do the same for the other 3?
Hey guys,
I need advice with fitting torsion beam suspension in the rear, I see that the BMW M# has such a system. I need to know how it works. MacPherson is straightforward but the torsion beam is different. I need to know what gets removed first, spring or shock? And also to put it all back together, what goes first?
Thanks in advance.
learned a lot. when i do my suspension, every time i jack up my car, the wheel would drop camber wise and when i drop it, it would stay camber. So i drive in back and forth to even it out to get a perfect measurement. it is just my tips with suspension but im no pro.
So what should you do to perfect the corner balance of the vehicle?? I adjust the my left front and now my rear right is off :/
How does your collar not move when you're adjusting the perch?
Rob, great looking garage. What type of lift or jack do you use? Great work on kw adjustment.
can u adjust ride height with stock suspension or would u need to buy new suspension?
Nice
Please correct me if I'm wrong, just some more confused people in the comments is all.
TLDR; Spring preload raises height, no or negative preload lowers height(loose springs if no helpers/tenders), both adjust how much bump travel.
The coilover world is odd and misinformed, KW is one of those companies that usually don't come with independent height and spring adjustments until you go all out with their track coils, because everyone has been setting them up wrong using the damper body and not the springs.
In this video, the suspension appears to be upside down and separated compared to many other vehicles, so move the spring perch down adds preload raising the height, less or negative preload would lower it.
The spring adjustment is the proper way, as it controls how much suspension travel you before hitting bump stops have AND the height, the body portion can be used to fine tune that more.
Going by the bottom or top body portion and not the spring adjustment can cause issues with travel depending on the current preload on the spring, either too little travel wasting performance or too much travel smashing the car into itself.
If you check out MCA suspension they have a ton of really good reads on how this works.
I want this guy to do mine!
So do you not have to adjust the shocks? only the spring and perch?
is it possible to raise a car with coilovers? for example I want to add it to a levorg and gain 5cm of more clearance over the standard ride height
I'm a bit confused. Is adjusting the lower perch different than adjusting the top in that adjusting the lower one has no affect on the height? It would seem that when you're corner balancing you're inherently changing the corner heights also, and afterward the heights are all slightly different, and uneven.
SWEET! Are you in SoCAL? I would pay for this service. I have an E46 M3 with ST coil overs, pretty much the same as KW.
awdaltima2 yeah and some height. I'm 6'7" which makes it hard to drive a lot of Japanese cars.
Would love to see more videos on this car
I like more Audis but to each his own ;)
Now you need a spring rater so you can maintain or change the roll couple to tune the way the car handles. You need to know where you started by rating the stock springs and knowing the rate percent front to rear. I've always preferred a car with a bit of push when it starts letting go. Loose can get you into trouble. And adjustable rate sway bar is nice for fine tuning the handle. Indy cars use an arm to the link that can be turned, it's a blade and as it rotates it will deflect some.
Which way do you turn the rear coil to raise the height of it my tires too close to my friend are going to raise my car up do you turn it to the right or to the left
It's 4,000 with driver and full tank. It's about 3690 without driver. I'm 6'7" and 270 (Brian)
I miss these days
awesome car, I'm jealous
Kind of. It's ride height adjustable but the spring is not on the shock body.
I just had a KW v2 installed on my 2011 e93, but looking for additional height in the rear... I bought the universal 15mm spacer from KW, but they do not seem to fit according to the shop? Anyone have info or advice on this? Or can recommend an alternative to add height to my new kit?
So if I just follow the manual to lower car, even the coil over model is specific I for my car model, the comer weight is still going to be incorrect right?
Is the tool universal? I have ABT adjustable springs (no coilovers) but have the same mechanism of collars and perk. I need to buy an ABT tool or can I use the one for all? TIA
subbed
How would you raise a porsche boxster s for offroading?
That really looks like the photos at the end were taken at the Culver City Park on Jefferson lol
So, to clarify, if my suspension was adjusted evenly then I potebtially could have one corner sit lower because of the weight if the fuel tank etc?
So to account for that I would raise the lowest corner until the gap from the tyre to arch is the same
Gonna post the link to the install vid?
Can I come to your house to corner balance my car too? LOL
Where u located I want to add kw on my 2014 q5
So clean, so perfect, awesome.
what kind of lift did u use?
i have questions... some things you did cover, but i want to be sure...1. what should be done first, the corner balancing or the alignment? 2. do the sway bars have to be disconnected? 3. should you add weight to simulate possible passengers? 4. lastly, should the static ride height be decided before the corner balancing? thanks in advance
how much did you charge him?
Like seeing this Video . . . .
is there coilovers for MB w210?
what, if any, suspension is on the lotus? nitron, kw, ohlin, gaz?
can you write an article about corner balance ?
How do you adjust damping?
Will this work to raise the height of my vehicle???
To maintain the corner balance when you lower the CoG you also need to use softer anti-roll bars.
softer or stiffer? asking because all mods of the sway bars is for thicker more rigid, first time I see somebody telling the opposite. thanks!
Giant for sure.
Where is his shop located I'd like to have my car done by him
Not a Bimmer fan, but good info here
so cornerbalancing is just adjusting each of the perches on the coilovers either up or down to handle the weight being transferred from the car?
nice one captain obvious
Iv wanted to buy that scale set for a while but all I find are new ones for like 1400-1700 bucks..not ready to make the commitment yet lol
How much would corner typically cost
Where are you located? so I can take my car for adjustment
and what if u dont have a scale?
is that a lotus elise with the front clam off? wow. hope to see a episode about lotuses...(mod, track)
Wilson Lim, it is indeed. We hope to do something on the elise at some point.
Do these coilovers have separate height adjustment to spring preload? By the looks of the vid it seemed you were adjusting ride height by raising and lowering the spring collars which would actually adjust spring preload as well....
You are correct. The helper springs help to adjust some of that pre-load.
+GTChannel is this set up fit e46 m3 ?
HELLO, COULD TRANSLATE THIS VIDEO IN SPANISH AND WELL KNOW WE NEED THIS CASE .
Hey if the collar is closest to the perch, is that lowering it or raising it? And if the collar is farther away from th perch is that raising it? Im not sure of the concept. I just installed coils on my rear yesterday (on an e46) and its way too low, im rubbing bad. And I have the perch closest to the collar.
Increasing the distance raises it, you should be able to raise the car quite a bit.
How did you manage to adjust the rears without having the perch rotating togehter with the ring? I have to diassemble the lower control arm to adjust the rears on my car.
I also wonder. Did you press the rear spring together. On my e92 335i the upper perch always rotates so I can not adjust the height
@@joakize I installed v3s on my car today and had that same issue. i did overcome it though. on my m4 atleast there is an opening in the control arm. u can put a socket extension with say a 22mm socket on the end up through the spring. I then used a very small jack to put light pressure on the middle of the perch. that stopped it from rotating and i could adjust the rear. i still needed the wheel off but atleast i didnt have to take the control arm off again.
05:29 spot on!
what year is this vehicle?
metric ftw! :D
Also forgot to mention to disconnect anti roll bars before corner weighting
Are adjustable coilovers universal? as in can they be fitted to any car or do you have to get get an adjustable coilover for a specific car?
Gotta get a setup for your car
You have to buy a set for your car
When I try to turn the perch on my rears the threads turn with it. Any idea how to fix this or what would even cause this? I can’t change the ride height because it’s basically spinning freely.
Also was wondering if you must always adjust the preload when adjusting the rear ride height.
You forgot about the part where the collar is seized on the perch threads and they both turn in unison
Amazing how little you find about weight balancing on YT. Guess it's all about ride height and looks, hm?
Trying to figure out why they are trying to make it unbalanced.. unless you are circletrack racing and putting wedge in it, it should be perfectly balanced.....
Anyone who might read this and needs to understand a better concept of the theory of how raising one corner affects the opposite side how to described it as “teeter tottering” can be better explained in some rc cars videos lol. Ironically we do this for rc car professional level racing. I just came here to confirm what I already knew from toys and make sure I applied the same concept to my real car since I’ve been fighting to adjust to corner height of my car. But basically set all your perches in pairs as a starting point and see where the car sits. For example on my 95 m3 the car is front left happy. When I raise the front left to get the fronts match by doing so I change the rear right height by leaning the cars weight in that corner making the rear right now settle more. Now to fix the height of the rear right what you want to do is raise the rear right while equally LOWERING the rear left to main the same height! It’s weird I know the fact that you want to raise or lower the height I just told you to raise on side and lower the other but for better visual representation this is why I said it can be better understood on a smaller scale rc model. If you want to learn more on the idea search up Alex hagberg X-ray rc car height adjustment. Many videos will come up on the topic and you can take away lots of useful information good luck 🤷🏼♂️
It's a 2008.
So corner balancing is just setting the ride height....After you've set the ride height?
No, the ride height doesn't change much visually when you corner balance. Small changes, especially with higher spring rates makes dramatic difference, but also weighting the car works in sort of a "voodoo" fashion which doesn't directly affect height, only weight. I'll explain...say you set your ride height and visually it looks good. You can actually redistribute the weight of the car and obtain the exact same visual ride height. Reason being, if you raise a corner, you actually increase the amount of weight it carries...so while you raise the perch, the weight increases so further compresses the spring. Once you raise the corner, the opposite corner will also gain weight. You're making small tweaks to each perch which don't visually change anything, but dramatically change distribution.
Dom said is not the car is the driver..
Is the rear suspension considered a coilover?
Officially yes but technically no lol
I just hope he uses more than %80 of the potential of the amazing hardware he has...probably not gonna happen but it's just funny to see people obsess about the theories and not actually drive the car...just do adjustments because it's supposed to be better...sigh
wait wait is that a p1 mclaren at 1:05 behind it in the driveway? :O
Changed out both struts on the front end of my bmw 325i, due to leaking oil. After the change my car is riding high in the front. The mechanic said the new struts were the right size, but that can’t be right. Can anybody explain why the car is riding higher in the front now, and what I should do to correct the problem. Thanks in advance for your input.
The oil leaking out of the struts may have lowered the right height over time.
Buy rears
If bilsteins they always have the spring perch in the wrong place by a few mm which raises the car that amount.
MK Maskari it wasn't easy and it's not something we'd feel comfortable sharing since it's not a particularly good idea. lol The right way to do it is to disconnect the lower control arm.
