Pepe_pr · 12-10-2010, 06:44 PM

Are the m3 4 doors sway bars front and back installable in the 4 doors 335i? the M3 are thicker and nicer that wimpy 335i ones.

that should bee a good mod

Yes. I believe. HP Autowerks sells m3 bars for e90s

Yes they are interchangeable.

Remember that making the car corner flat is not the most desirable. Having too stiff of a sway bar can hurt cornering performance.

That said, if you have proper spring rates and dampening, the M Sport sways are great for E90 335i's, and the M3 sways are good.

Just wanna confirm the e90 M3 sway bars would fit my e90 325i as well? I just called the parts supplier and the guy wasn't sure about it just kept on saying they are quite different. Anyone has experience in both M3 & Msport? Any comments for the difference?

Guys, prepare yourself that it will take the installer up to 6-7 hour to install just the rear sway bar. It's well worth it once done. While the sub rear frame is down and out, I highly recommend changing out the rear sub frame bushings to the M3 versions. I didn't do this and now I'm paying twice for the same procedure (even though it has been over a year ago since the installation).

North American cars with M-Sport pkg come with the sport pkg suspension, not the M-Sport suspension that's avail in Europe, and referenced above.
