Setup Coilover Preload and Ride Height 

This is the most clear tutorial I've ever watched thank you!

This is the best video on this that I have found. Be careful when you set the preload. You do not want to turn the top ring rather lock it in place by the force of the bottom ring. If you look at your procedure you actually turn the top ring causing some loss of preload. Yes I am being super picky but if you go through all of the work then this is important . Thank you for posting!

Perfect! I’m pretty sure I messed up my preload by about half a turn when installing my coil overs. This cleared up all my problems and now I just need to set it to what is in the instructions and boom, solid

Easiest instructional video I’ve seen on RU-vid cause others extrapolate too much and some are so vague to the point you gotta watch the video 10x’s.. I only had to watch once. My project is a 98 Lexus LS and I’m working with Megan Racing EZII coil-over system and 20” Enkei Lusso.

Literally THE MOST CLEAREST OF CLEAR video on coilover adjustment ever

This is by far the best video I’ve ever seen on adjusting ride height and pre load on coilovers

The only video where i fully understood the process!!! You just saved me from paying someone else to do this for me!! Awesome!!!!!!

Just found this video...And have to say, this video alone has now made me more comfortable with fianlly doing my own install. While I knew about the lower part helping adjust ride height, I never knew you could leave it on the car to adjust that part..This helped me (And saved me tons of time) SO much. greta video!!

Such clarity and detail .. I will be raising my car and this video is just what i needed... thank you very much mate

Thank you so much for this video, I was having trouble with preload. You explained everything I needed to know clearly and perfectly!

Great video, clear, and detailed! Good job! In the process of installing coilovers on my 06 Mustang GT.

Even if you dont have bc coils! This process is the same for all coilovers! Thanks so much for a clear walk through!😁

Yeah I have to say. You where very clear on explaining how to preload and adjust. Very good job. High five man.

This is the only video that clearly explains this . Thank you ! I’ve been looking for ages

Very clear explaining how to set up properly. Thanks! As soon as it gets warm the GTO will be set up properly.

Looks great ray your turning your Mercedes into a cool ride by the time your done with all the upgrades your Benz going to look so awesome.

Just stumbled upon this gem of a video, just installed some BC BR’s on my Focus ST this weekend....this video is great. Thank you.

I really liked the part where George Clooney's character even through isolation was able to adapt to a somewhat normal way of life. Great Job!

Damn you made this super easy to understand honestly lol. I don't know if all coilovers come with the preload set to where it needs to be but yeah you did a great job of explaining this. Thanks!

Best clarification of preload and adjustment. I couldn't find anyone doing it right. Thank you. Just picked up a set and I'm ready to go. Lol

The best video of coilovers It helps me very much Thank you From Tijuana Mexico

Lefty Loosy but also LOWERS the car. Righty Tighty, but also RAISES the car. Thats how I remember it!

Best video ive seen, i didnt even know you could adjust the coilover without taking it off 😂 im new to all this

New to coilovers. This video was extremely informative. Thank you!

you are a life saver mate!! While lowering my Teen Flex Z, the preload lock got loose and I kind of messed up with the preload setting even though the height is same on both coilovers :( Now I can reset it back!!

Wow this video was a big help I adjusted my coilovers and was messing with the preload thinking it was ride height and my spring was able to move up and down like 2 inches. Yikes will be fixing it

Most springs on the market sags over time and after 1 year that 4mm preload might not be enough. I will recommend 8-10mm depending on the length of the free length spring. The other way is to reset the spring preload during your usual oil change interval.

I've got some BC Racing BR's on the way! My first set of coilovers, so this has helped a lot. thanks man!

Best tutorial I’ve watched. Thank you!

Thank you so much dude! Just received mine, will be installing them and this cleared up my questions!

wow... crystal clear instructions and explanation. good job !

Fantastic video- thank you. I messed up adjusting the ride height on my 2005 R53 Mini by adjusting the lower spring collar, thinking that would change ride height - and have been experiencing terrible ride quality since doing it - you just made me realise that basically removed all the preload from the spring completely (it was actually still loose) by doing this and that will hopefully be the cause of the terrible crashy ride quality I had... Just adjusted it and will feedback if this fixed the issue!

Finally someone gives a good explanation!!! Great video

Thought it was just a slap on part. Thanks for explaining pre-load.

Wow fantastic! This makes so much sense now

Thank you. Straight forward. Other videos suck.

Thank you. You did an excellent job. Much appreciated and blessings!

Thank you for one of the most concise videos on all of RU-vid. God, I am sick to death of the legion of clown video productions out there!

if you lowered it more to where the tires are flush with the fender, what prevents the tire from hitting the fender when you turn?

damn you never cut to after you did the final adjustment haha. Awesome video man, definitely learned a few things. I was doing some things very wrong.

Great video! Exactly what wanted to know. Great work!

Great vid man!!! Im going to redo my fronts after watching this just to make sure. What tips do you have for the rear? I have divorced rear coil overs and cant find a clear video showing the correct way to do it.

Very clear and easy to follow, thanks!

Thanks bro... New to the BMW scene. I appreciate your video on this! Peace...

You earned a sub my friend ! Very clear & quality content. straight to the point & very informative. & universal across all coilovers. Prefect for a novice to the veteran technician!

Very good job sir.clear turorial.follow from japan

Did you ever made an video for how to adjust the coilover on the rear?

Finally a clear tutorial

Great video and explanation.

Wow I didn't know Doctor Banner was also a car enthusiast! Awesome video sir!

Thanks man I’ll be doing that tomorrow.

Preloading your coil overs can make a dramatic improvement, and the only way you'll know whether it makes a difference is to make adjustments, document and test. In my case, adding 200lbs of preload made a tremendous difference in that my suspension had less compression modulation and less rebound pressure which translated to a smoother ride. -2 cents

The best explanation video thanks♥️

Your video jus popped up, thanks I have BCR coming in tomorrow for a Lexus 250 F sport, any recommendations? That be helpful

I'm thinking about getting a set of BC coilovers. Could you give me an update on them? Are they still working good? Some peeps in tube land don't like them or are having problems w/ them. Thanks for any info and the watch rulz btw!

My Gawd man! It finally makes sense! 👍👍👍

thank you man fr my front end was sooooo stiff i could not drive now i know how to fix and have my car on the floor slame

Great video dude!

Very informative tks for this video I know how to set my adjustments..

Very good explanation

You explained the front but how do you readjust the height on the rear part of the vehicle i have a shock and spring like yours thers no video i cant seem to find one

Over time. Can the lower perch come undone? Is that a possibility? I’ve had a tire blowout and one side of my coil over rubs/clunks now

What would be your opinion on bagging a w204, Right now I’m in a bit of a decision war on should I just get coilovers witch is cheaper or just pay a bit more to bag the car 🤯

Again great job! Use a old ruler with mm reading. I found it easier to back out the center locknut on the strut mount itself. Just back the center locknut out ( loosen it) about 2 full turns only. Go back under the wheel wells and use only the upper center collar to turn it left or right, inorder to raise or lower the ride height. Measure before and after with an old ruler, using millimeters. Remember not to adjust the preload on the spring! Loosen only the lower collar, the one closest to the brake rotor/caliper. Remember to tighten the lower collar only with a blunt drift and hammer. Don't hammer too much, just about a 1/8" or so. Remember to tighten down center locknut on the strut mount to proper torque values. Remember too have your front end alignment checked by a professional shop when finished! One special note to remember, measure between the inside of the lower collar and the inside of the center collar before you start, take pictures for references. You want to make sure you have the factory settings as reference before making any adjustments! Hope this helps!

Very clear explanation.

Do you have instructions for how to lower the rear of the car?

Rookie question but the process is the same for the rears ?

What are you using to accurately copy the ride height to the other side?

What’s the factory ride height compared to where you liked it? Have you any issues scrapping bottom of bumper on slopes?

Great info. Good job.

I think it will be rare that the distance from perch to perch will be the same on both sides if you are aiming to achieve the same aesthetic looking ride height. You might find a descrepency on the perches of up to 10mm between sides is needed to get a similar ride height.

Does your spring move left to right freely? Like if you’re turning it with both hands?

Can you please tell me how is the new height of this car in terms of milimeters after coilover?

Can you do a instruction video for the rear too? Thanks.

Could you provide best way to lower front of a 1983 W126 300SD ? I am Planing to get 17” wheels . Also , advise on best amplifier and speakers to use with first generation Becker radio and installation. Thank you very much for your videos and advise.

i have coilovers fully threaded and my ride is way to stiff how to soften my ride pls help

do we need to spooring the car again after adjust the ride height ?

Great video thank you

I'm new to coilovers, just put a set of Pedders xA's on my GTO... do you set the preload 1st, then adjust ride height, or ones it not matter?

You explained the preload so well compared to the other videos. Thank you but have one question. Would I need alignment whenever I adjust my ride height?

They look great! One question about the aftermarket wheels, how do you know how strong they are? I was watching AutoVlog's video and saw that his aftermarket wheels cracked after driving over a small pothole..... something which wouldn't have happened to the stock Mercedes wheels. Are these aftermarket wheels genuinely well built (to Mercedes standards)?

Hi. 2 years late here. What should I do if the shocks have been adjusted to the same length but there's a 4-5mm height difference between the two sides? I was on level ground but still I turned my car around to make sure and still. a 4-5mm difference.

haha that hand pre-load had me cracking up lol

Felt like I was watching chrisfix video lol

do i need alignment everytime i adjust the height?

how do you set preload on coilovers in the rear on cars that have the strut and spring seperate?

Do a video for the Rears

Thanks so much!

If the tire then rubs the inside tire well liner on bumps and potholes should one increase the preload or increase the height?

Hey Raymond, did you ever look into getting a new front and rear stabilizer bar? I found one from Eibach but I think it’s only for the RWD w204s..

For what I understood. I shouldn't mess with the spring load unless I'm going to a track race or bs like that???

What brand coilovers were they? Never mind re watched

How did you lower the rears???

I did this and my (Driver side) completely drooped after I took it on a drive and now the spring is fully compressed. when I jacked up my car, the springs do not decompress. I had to angle my tire out of the hub. Has anyone encountered this?

I have the same coilovers Mercedes accept my rear the spring is separate from the shock so how do you raise the car up do turn the spring or do you turn the shock? Thanks

I guess your right to say most ppl won’t ever adjust preload. But those that do should be corner balancing. That’s where you benefit from preload. They way your doing it is fine for safety but your limiting functionality. Good stuff tho. I needed to see how BC we’re adjusted.

Is better to adjust preload before installing on car?

Dude, is that a Casio Digital Watch from 1982 you're wearing...?

Funny. I actually sold my C63 to buy a Vette and build it, this helped me a ton with my car. I miss my Mercedes. Lol

BC or Siliver's Neomax? I CANNOT DECIDE?!?!? Any advice? Thanks in advance.
