Coilovers: KW ST or BC Racing

I can't seem to decide which coilovers to get. From what I hear, the BC Racing coils squeak but have front camber plates. The KW ST coils don't squeak, but don't have front camber plates. Also, the BC Racing's warranty is much better. They're both about the same price. Suggestions?

Edit: Any feedback on D2 Racing or Sonic Tuning coil overs?

I have ST coilovers and couldnt be happier with the for the price. Im not slamming down or tracking so i dont really need the front camber right now. although i probably will end up getting camber plates at some point.

Thanks man. I guess I'll be looking into Sonic Tuning and D2 Racing now. Ahhh, the choices are endless. It's a lot of money so my choice better be the right one.

I have sonic tuning coilovers and love it. Feels near identical to sport suspension but handles on rails.

Why the need for camber plates? I've got sonic tuning coils on mine without the camber plates. It's a nice setup.

I'm pretty sure the Sonic Tuning coils have camber plates though...

I would need camber plates if I plan on super slamming my car. Not sure how low I actually plan on going yet, so it would be nice to have the option to introduce camber if needed. I think I'm taking the KW ST off the list for that reason. Camber plates cost a fortune if purchased separately.

That's incorrect. I just installed the coils myself... No camber plates.

U can introduce some camber by just shifting the top hats. With the stock top hats u would need to remove the alignment nipple to do so. With my sonics they were a full replacement so I was able to shift it to get minimal neg camber.

Hope this helps...

Odd, it says they come with camber plates here: http://www.sonictuning.com/bmw/bmw-3...ber-plate.html

Thanks for the help though. Maybe you got a different set? Not sure honestly.

the one with camber plate its s3, slightly more expensive than s1. how do you guys lie the s1? I've been thinking about getting one but i heard it's too stiff for daily drive even on softest setting.

I've been riding on it for the last week and a half with long road trips in between. Gotta say, compared to stock sport susp it's very comfortable. Firm ride and I feel more comfortable pushing it. The stock sports lost its composure sometimes when hitting bumps

I also gotta add though that it's a hassle adjusting the front height as u need to remove it partially from the bottom clamp to move it up and down. Other than that, the adjustable dampening is a plus.

Thanks for the kind words folks!

All of our coilover includes Top Hat, the S3 has adjustable camber plate.

You can drop up to 3 inches.

The coilover is designed to give you comfort for daily driving, and easy adjustment for damping so you can take it out to track for the weekend.

Any questions feel free to PM or email us.

For Limited time we have a free shipping promo for the S1 and S3!

I have my ST v1 about halfway down the threading on the front wheels and am 0.5" gap from tire. You can lower it until it rubs, and you can keep going lol. The rears sit perfectly on the lowest setting. If you need to go lower, you can remove the perch.

Is that on the softest setting? Do you track or just daily drive?

I've used KW and ST. Unless you need adjustable damping/rebound ST is the best value IMO.
