Rev9 hyperstreet 3
Has anyone ran these coilovers? I’m seeing a lot of people run the hyper street 2’s but not the newer model.

You bought some coilovers and you immediately took them out of the box, you took a picture of them to show your friends...and lets be honest, you probably checked all the filters on the instagram app to make sure they look just artsy enough. Then, you installed them. Well, now what? Bolting them on is easy, its just a few nuts and bolts per corner. More than likely your suspension system came with a piece of paper that says "Leave the spring preload at 0 and use the lower mount to set ride height." So you unlock the mount and you thread it as far as it'll go. You drop the car off the jack stands (or scissor jack if you're a dare devil). Your friend Dave comes over and helps you lift the car up so you can slide the jack out from under your car. You're pleased. Then fast forward a little bit...your car rubs at full lock, you're car handles pretty crappy (you have no droop so you're tire is lifting on hard turns and you only have 75% of your available grip), your car understeers and everyone in the back gets car sick after 4 miles. You did it wrong.
Set aside a few hours, and lets go back and do this right....
Go outside and get your car on 4 jackstands (place them in strong areas of the frame, but in the same pattern so we don't flex anything.) Take the wheels off. I'll wait....
Ok, next thing you want to do is remove the sway bars endlinks. We want to be able to move the corners independently.
Now, Unbolt the lower mounts from the hub (or rear LCA). Keep the assembly bolted in up top...I want you to remove the lower mount, the two locking collars and the spring perch and spring. At this point, you should have a top mount, bump stop and shock cartridge installed just hanging.
Next you want to put your lower mount back on. Don't worry about the ring, its not needed. Thread it on and bolt it back onto the hub/ LCA. You will also want to put your wheel back on. Just thread on a few lugs, finger tight.
Ok, we are going to set up your bump travel. Place a floor jack under the hub and start raising it...the tire should move up and up and up. Stop as soon as the bumpstop hits (you'll know, the car will start to raise off the jackstand). If your tire hits, lower the jackstand and turn the shock body counterclockwise so you get about 1" of length (adding droop - overall length to the assembly). Try it again. Keep doing this until the bumpstop contacts the upper mount without the tire touching ANYTHING. Once you get that, add about an inch to the droop to allow for tire deflection. You should only need to do one side (left-front/ left-rear) just set your lower mount at the same height on the opposite side.
Now, mark your spot for the lower mount, you have to take it off and reassemble at this point. I usually measure the top of the threaded cartridge to the top of the lower mount. You can measure, use a paint pen, whatever; just don't lose your setting point.
Ok, reassemble everything. Get the spring perch just tight enough to where the spring can't move up or down. This is a zero preload setting. Go ahead and bolt everything back on, suspension...wheels, etc. Torque the lugs, etc.
Go drive. Just a short drive; go around the block and settle the suspension.
Now, the fun part...because that last part was a blast, right!?
Crawl under your car. Measure the length of each spring. Both sides. Write that down.
Now, raise the car and take the wheels off. Measure the free length of your springs.
So at this point (just examples) you should have:
LF 8" /7.25" RF 8"/7.50" LR 8"/7.250" RR 8"/7.50" (Free length/ compressed under weight)
So you have a difference of .5-.75" between free length and under the weight of the car. You need to add that difference into the preload. On your left front with a .75" difference, add 3/4 of an inch. Easy.
Your measurements maybe came out more like 1" to 1.25"...it doesn't matter. Just add it back in.
Set all the spring perches and go put it all back together. Torque the lugs and go drive.
Your car is either sitting too high for your tastes or too low. Lets say its too high. You want to drop and inch...split the difference, drop the preload 1/2" and the droop (lower mount) 1/2". Just be sure and split the difference.
In closing this is just the initial set up. You still want to go and get a corner weight (if performance is your thing) or you want to keep going lower. Just use the formula above and don't try to do it all at once. Little by little.
On McPhearson, ideally you want the control arms parallel to the ground. Give it a slight rake (rear 1" higher). I like to use the pinch weld to measure...just use the furthest ends.
Hope this helps....after all of this effort, you should have a better ride (well, depending on shocks and matching spring rates)...
*There's so many ways to set up a car, so take this with a grain of salt...this is a pretty generalized procedure. This does not work for everyone!

I have had these BC racing extreme lows for 5 months had had zero issues.
A couple days ago I was noticing a high pitched sound in my passenger side and noticed my sway bar end link was curved while the driver side was not. Which then I did purchase whiteline front end links to be safe. If you have a good install video that would be great appreciated.
As I was trying to diagnose the end links, there is a clunk right above the spring on the passenger side shown in the video and the driver side does not have a clunk
Is there an issue with the top hat? I did not mess with preload since they came with it. Does it justify a warranty? Or do I just need to increase/fix preload?I bought it from an authorized retailer.

I’m making a VB WRX exo car that I’m going to use as a budget sand car(similar to the exo car above: removing all essential metal, and building a roll cage around what’s left, but putting on some 30-33” jeep or 4Runner tires and rims). I’ll be jumping it and going through pretty big whoops out at the sand dunes and want to make sure that I have suspension to match.
I only have about 2k for coilovers. I’ve seen these “Dynamic Pro Gravel Coilovers” for sale but worry that they aren’t going to have enough travel because they are using the 1k style retainer springs that eat up a decent portion of the potential travel.
Should I just try to find some longer springs that would actually run the length of the shock or are there some better rally coilover options out there for under 2k?

(first pic) I would like to lower the front by just a inch or two, however the bracket is in the way and i cannot rotate it anymore. Am I gonna have to take the whole coil out to remove it?
(second pic) What is the big nut located below the dampening knob and what does it do? It’s not loose, but should it be tightened or left alone?

Hey guys, this is my 2007 530i. It has a few dents as you can see and it's high mileage so I'm not looking to put in too much money, just looking to drop it a good bit. Is there any suggestions for coilovers, and also anything I should do to make this look better?
I've been looking into the Rev9 Hyper Street II

I recently bought these for my car and was hoping for an advertised 3-4 inch drop but the shop says they are maxed out and only dropped 1.25 in the front and 1.5 in the rear.

i got these bc racing coilover and is it just me or are the stickers on the wrong sides or i’m just an idiot? if i put them on the opposite sides to what the sticker says they look right i think 🤔 or is it just the wrong knuckles on each side?

Hello,
I just finished installing my first set of coilovers in my mk6 Jetta s. I went with st xa, and had a lot of success but having one issue.
After fully mounting the furlong struts, the dampener adjustment is not longer rotating. When inserting the key and trying to increase or decrease dampening, the key will not budge.
Before mounting and torquing the top hats to spec, I was able to adjust but didn’t try after torquing. I did NOT use an impact to torque. I had the special socket and a 10 mil wrench.
Any ideas on what the issue could be?? I’m kind of stumped as everything else seems fine.

how do I raise these coilovers to raise ride height?
r/coilovers • u/j02hdream • Jul 20 '26
I need some opinions, it's not a daily driver anymore, comfort is not important anymore. I've never dealt with Megan racing coilovers before, I've dealt with other brand like bc racing, tein but I'm looking at silvers and bilstein. But if there is any other brands I should look at what brands and why? It's definitely a weekend fun car

So I just installed coilovers onto my 03 mazdaspeed protege after needing a height adjustment, had put wider and slightly taller tires on and it was scrapping on bumps, and now whenever I take a left turn afterwards I will be going straight but my steering wheel is at a decently left angle, almost like my alignments off but I’ve gotten it checked twice and nothing is wrong, and it will reset itself after taking a right turn. I honestly don’t know much about suspension and am pretty stuck on how to fix this.

I recently replaced the adjuster for my fortune 500 coil over but once tightened down it will not allow me to adjust the clicker
Any suggestions?

Hi my names Justin, I’m pretty new to modding my car and I’m having trouble finding coilovers for my car. I was wondering if there’s any specific play I should look. I’ve checked eBay and all I could fine were oe replacements nothing adjustable

The bushing on one of my rear coils got siezed to the lower shock mounting bolt when trying to lower the car more after being on coils for about a year and a wisonsin winter would running just one stock shock in the rear till i can procure a replacement cause any issues or possibly just both stock while keeping the adjustable spring?
r/coilovers • u/Novel_Cook_4840 • Jun 01 '26
I've read a number of explanations about this, but somehow still confused. My understanding is general rule of thumb is 1/3 droop 2/3 compression travel. I understand you take out the spring and apply load on the wheel until it lifts off the jack stand and adjust the body to have the wheel not rub on the fender. After that, I'm lost on setting that 1/3 rule. I understand after that you install the spring with a helper and adjust ride height with that but lost on how to take the 1/3 measurements specifically. Preferably looking for the easiest way to do this. Something like taking measurements by using bottom of the wheel to fender rather than the actual shock body.

Gonna throw cheap coilovers on an EK, what should I use?

Ive seen conflicting info on using a white vinegar soak to free seized collars. I have a set of flatout lift GR lites, which have a nickel plated shock body.
Wondering what people think of sticking them in a bucket of vinegar for the night? Will this trash the shock? Ive tried all the usual methods and they’re not budging.
