1M rear subframe bushings in 135i?

Ston · 12-17-2023, 04:18 AM

Hi, I've got a new to me e82 135i and was wondering if the 1M rear subframe bushing will fit?

I've tried some searches, and I know Turner do a set, but I'm in the UK.

Would these fit?

It's not a daily driver and I'm not concerned with additional noise.

Thanks in advance.

Yes they fit, this is a common upgrade.

Yes they will fit, replacing regular 135i RSFB for M3 ones is a popular mod. Do note however that there exist some 2 piece RSFB that are aluminum (revshift) which makes instalation easier since you dont have to get off the subframe completely.

I upgraded to M3 RSFBs and have no regrets. I seem sensitive to NVH, thus switching to urethane or aluminum wasn't really a consideration.

I have a set of M3 RSFB that I have decided not to install and need to sell.

I just installed 034 motorsport aluminum inserts the other day. Installation was easy as pie (<2 hours dorking around), and they're under $200 shipped on FCPEuro. Wayyy easier than dropping the subframe, fighting the old bushings out, pressing new ones in, and having to open up/bleed the rear brake system. Also I really don't think the end result would be much different than M3 bushings, you still have rubber in there to make for some compliance. NVH increase was little to none, and I consider myself to be pretty sensitive to these things. Controlling slip angle feels 1000x more predictable now. Before the rear end was squirming all over the place any time you broke the tires loose.
