yesp, i was gonna say that but i didnt want to give ya false info haha

i think if you run smaller wheels/tires the sway bar will be closer to the ground

Yes, like I did this morning. Non squished dead kitty and exhaust/swaybar don't play nice together. lol

Anyone running the bc racing coilovers? Thinking of getting them. Not really interested in the stance. But more the performance of them on a track or spirited driving I like that you can adjust them for rebound and dampening so I'm assuming they should be fine but just curious if anyone has had any issues? Thanks

the bc racing BR series. they are on the the first page here. they are 30 way adjustable for dampening and rebound, and ride height. i here a lot of people say that the coilovers are not good option for the track, but i dont see how thats possible if they are adjustable for rebound and dampening i dont see how you couldnt tune them the way you want. do people just not know how to tune suspension so they say they suck? or are the adjutments not enough to fine tune it? i like the bc racing BR series because they do both rebound and dampening making it a lot more adjustable than some of the others. but if another brand is better for the track and someone can tell me why besides saying because its better. id appreciate the tips. thanks.

I'm not saying you're wrong but here's from the website. So idk how they adjust for both?

30 levels of damping force adjustment, adjust compression/rebound. I don't know much about suspension this is my first set of coilovers. Also curious on what spring rates should I use? They offer custom spring rates. They come with 6k/6k I don't plan on dropping the full 3" but maybe 1.5-2. Do you recommend any other coilovers besides the bc?

I have the br series and they are not to bad. They have only been less than two weeks. They seem to ride decent as long as the road is not terrible. I have not made any adjustments yet except for being almost all the way down. No fine tuning if you will

^^you better get an alignment


And i have the br series too. They use one adjustment knob for both compression and rebound they arent separate. Im going for low but they did handle great when i first installed them.

You could probably go 8k all around

can anyone explain spring rate to me? and why i would want to do 8k all the way around when other companys are doing like 7.5k up front 4k in rear? so im curious as to why these are so different in spring rates? thanks. are there any companies that make coil overs that are like the zr series? i really want the zr series but they dont make them for our cars.. which sucks id really like a nice set of coilovers. i wouldnt mind putting 2k into them if they were fully adjustable. like the zr series. any other brands that do that? thanks again for the help.

i ended up emailing BC racing to see if they allow me to upgrade to the ER series for the extra money. they say they dont support all models for this upgrade. but if they do ill be doing that. they are not only adjustable for rebound and compression individually but also have a dual piston set up and a external reservoir. so hopefully they allow that. i was looking at the AST 5200 as well because they say they can make them fit any car, but they want 3500 for those. i dont wanna spend that much. the BC will end up just shy of 2k not to bad for being fully adjustable like i want.


so they responded. and they cant do the ER series, but they do, do the RM series one step up from the BR series. and they recommend the 8k/8k. and they valve it for that spring rate as well. so i think ill do that route unless anyone has any better options?

Ive just heard theyre more suited towards track use. If you really want handling get koni shocks and powell springs

Alright so I've been reading up on this lately and it seems if you want the best performance your going to want to go with koni yellow race struts not the sport ones and powell springs? What about coilovers? Whats the best performance coilovers out there?

What about adjust-ability?

I have been on Ksport Kontrol Pros for almost 30k miles and cannot complain about them one bit. Have taken a couple longer trips, including one over 3,100 miles in a week, and didn't feel like I had been beaten with a stick. lol They handle great and the 32 way adjustability makes fine tuning them fairly easy, but the rear adjustment is annoying as you have to remove the head of the shock to access them. I currently am running them with Powell's trailing CABs, Whiteline Performance adjustable endlinks, Prothane swaybar bushings, and rear ottp hardcore bar. All works quite well together.

I think the mistake is we mess with the shock length thinking it helps to lower the car more. all it really does is make the car ride like ass. The ride is night and day different than it was out of the box. My girlfriend actually likes the car lowered now because it glides like stock again with just a very, very faint bounce. I hope this helps some folks who are complaining about the ride quality. And thanks to Stance Customer Service for helping me out and making their product shine it should now.



Everything is ratcheted down as far down as they go. And I removed one ring each from each coil over.
> The front strut dampers are set at 4 or 5 clicks from full stiff. The rear shock damper is set 4 clicks from full stiff.
> Speed Bumps, steep driveways, dips, rail road crossings...you have to slowwww way down and crawl over them (usually on an angle). Sadly low is a lifestyle, so you would have to change your driving habits a little to enjoy the look.
> I not only rolled my fenders, but had to do a slight pull on them too because the backspacing on my rims asked for it in order to get the little bit of tuck I got.

thanks guys, let me know if you get them and need any more info.
THANK YOU THANK YOU THANK YOU!!!

I have been trying to dial out the last bit of bounciness ive had for the last week, and this was the key!!!

When I installed my coilovers, I had no real clue what I was doing. I mean I knew enough to disassemble, clean, reassemble, re-boot, and install them, but setting them up is the REAL tricky part. When I did the rear, I had set the shocks to a height I thought would work, and jacked the rear up to meet the shock, compressing the springs slightly, rather then seating the spring, and adjusting the shock to match that.

Initially I did the rear first, and drove about 5 km's with the stock front setup to make sure there were no bangs. I didn't feel the bounciness then. So when I installed the fronts, and the bounciness started, I assumed it was the front.

So I released the 4mm preload I had in the front, and stiffened the shocks. It helped, but still didn't solve my issue.

So I read this thread in its entirety to see if others had the same issue. I read your comments, and thought I'd try it. And what do you know, IT WORKED!!

I guess because the front is so much stiffer than stock, it started affecting the rear a lot more.

I still have to drive more to make sure its better, but so far, its a world of difference!

Again...THANK YOU THANK YOU THANK YOU!!!!

I just got some HSD coilovers and was wondering based on how they are in the picture how close to a stock height would this be if you can tell?
