m3 suspension on 335xi
Hey everyone, so i have decided that my next mod is going to be to upgrade to some kw v1s to clean up the sloppy xi suspension and rid myself of the nasty xi fender gap.. My question is what else can i do to improve the suspension, i have read numerous threads about m3 suspension bits on the 335i however information about m3 parts on the xi is a little more scarce.. From my research i found that it seems only rear m3 parts will work on the xi but front parts will not.. In that case is it worth it to just do the rears? I plan on doing maybe a few drags at the track a season but mostly just normal daily driving. Any input from xi guys using m3 suspension parts would be greatly appreciated!

The biggest improvements with the M3 parts are additional camber up front, along with stiffer bushings. The added camber improves turn in response and front end grip.
If you can't use the M3 front pieces, don't bother with the rears. Also, the M3 rear lower control arms require different shocks than the regular 3 series, so you'd also need to get different KW rear shocks to fit the M3 lower control arm. you can always get a front camber plates if you feel the need for more negative camber up front. But for what you said about your driving, you probably won't benefit much from them |

I first had H&R springs and bilstein shocks which created a super harsh ride on New Jersey roads plus the rear was too low and the the front not low enough. I then swapped the H&R springs with some 335i Eibach springs and the drop was perfect and the ride comfort was much improved. The car still felt a little sloppy and unpredictable. Then I got rear M subframe bushings and rear M swaybars and WOW what an improvement. I have no idea what the poster above was talking about when he said not to do the rear M parts. That is just not true. Now if we could on improve the steering response/ratio I would be in heaven. Good luck.

It really all depends on what you want. Since you are getting V1s, I would assume you just want the car to have a nice drop and a somewhat improved handling situation. I would recommend splurging on a proper set of coils just because you will want to upgrade the slushy oem shocks later on. In terms of the M3 bits, I would recommend the bushings, guide rod, upper links, and rear sway (personal preference). The rear M3 control arms do require different shocks. My recommendation would be to save up, get a nice set of coils and do the M3 suspension bits all at once. You won't regret it.

Like say getting KW v3's for the M3 coupled with the full rear M3 suspension conversion? Since the M3 front sway bar won't fit... is there another after market product which is suggested to use? Any other parts that won't fit on my 335xi which I can look for in after market parts? I'm not looking to lower my car, i just want a better handling ride (I've already ditched the RFTs). I'm more of a one shot kinda guy when it comes to modding, I like to get all my parts together and just have my shop just do it all in one go. After I do this conversion... when I get my alignment done... do they put it on the machine saying it's an M3 and use those specs or still use the 335xi specs to dial it in? Final question... would I need to get camber plates? If so which kind should I get? What happens to that locking pin for the camber... is that removed permanently or do I still use it? |
