Of course I would've bought new if I had wanted to spend another $700. I love buying used things because they're almost always as well taken care of as everything I have on my car currently and it saves me a ton of money. I'm sure i'll have no problems with these coils but if I do I always have the KW lifetime warranty

If you buy used you don't have a warranty. Only the OG owner does. Like I said, get rid of them while you can. Even if you did the warranty protects against manufacture defects, not track abuse.

I can gaurentee KW will honor the warranty and replace them if I have an issue. Coilovers are meant to be tracked not babied imo so I doubt that would prevent them from replacing them. I'd call it track use not abuse. I don't even know how many times they were brought to the track but if KW coils can't handle normal track use, they shouldn't even be considered high quality coils.

If you are the second owner, and have an issue not related to manufacturing I very highly doubt that. Anyhow, good luck. If you don't take my advice so be it. I just know I would never ever put those on my personal car.

Yea to each their own I guess. I can provide KW with the receipt from the original purchase and I doubt they would be that strict if something went wrong. They're an extremely reputable company known for great customer service so i'm not worried at all. My theory behind buying all used parts is as long as they're not broken buying someones parts that have 8k on them is no different from having parts on my car that I bought new and driving them past 8k. I love saving money wherever I can so I try to buy used whenever I find a good deal and save some $$. I should have a thread up with pics and thoughts after they get installed this weekend

If I'm not mistaken, the front one is missing its dust cover. Could this be a sign of excess wear or problem? How important are the dust covers?

Never heard of a dust cover... Do you mean the bump stop? If so the front has the bump stop it's the yellow part

Edit: Did some googling and I know what your talking about. Isn't that the black thing under the bumpstop? I was also reading a lot of people reuse the oem dust covers?

Yes. That black cover. I believe it's supposed to stay connected to the lower portion to keep dirt away from the piston.

Yea I checked with KW and it's not a big deal. They're like $10 so I ordered some new ones but i'm installing it anyway. They said theres no issue running without it for a while you just shouldn't do it for that long

[JelloXI]

so just double checking but when the list says BMW performance springs, you guys mean the Yellow springs correct?

cuz im on tischers website and there is no specification.

also im planning on running the yellow springs on Bilstein HDs

im not looking for a height drop but just more of a stiffer suspension.

would the stock springs on HDs be good enough or would i feel more of a difference if i slapped the yellow springs on too?

[critical05]

I would suggest that anyone changing out springs or struts to inspect the dust cover before you tear into it. Its a shame if you have to reinstall a torn boot just cause you don't have one.

Strut bellow part number: 31331094749 (not sure about LCI)

Also do some research about front bump stops when buying lowering springs. Bilstein have internal bump stops, koni and stock struts need external bump stops. Koni does not supply them with their yellows. Some have been fine but I had to cut mine at the time of my eibach and koni install. I later tore it apart again to install shorter bump stops, I chose the e36 M3 (same as z3 m) as others have recommended. I wish I would have done some more research before and spared another 3 hours to tear the front suspension apart again.

E36 m3 bump stop part number: 31332225377

So best option for a little drop and a little stiffer ride would be Eibach pro spring set with Bilstein B8 struts and shocks, right?

i have 2008 335xi with sport package, looking at just replacing the springs with eibach ones, anyone on here that has done this? just like to get some feedback, thanks

[ccraig13]

If you do a search, you'll find another guy with a 335i who did that and really loved the results.

http://www.lowriders.ca/2092-140-Pro-Kit-Performance-Springs-p/2092.140.htm do these fit on a 2008 335xi sedan with sport package, looking to keep the factory suspension with these springs, thank you

Has anyone changed out the rear rotors and calipers for the M3 variants? Hawk Blue brake pads aren't available for the 335.
