Rear Subframe Bushings Question?
Hi, I recently acquired a CPO 2012 135I and I see that lot of the members here are replacing their RSFB with the M3 bushings. My questions is, since I bought the car used, how can I tell which bushings are mounted on the car by just looking at them? I don't want to buy the M3 bushings only to find out that they are already mounted in the car. Thanks!

i don't remember how exactly looks like fitted on the car, but i think you can remove one of the bolts with large washer and see which bushes type you have.

You can tell by looking. The stockers have quite a bit of airgap in them. The M3 version are solid rubber.
M3 on left, stock on right. |

they are covered with large washer, so anyway, you need to remove one of the bolts |

Hell for even easier you can go over a speed bump slowly and compare how close the front and rears recovery time is. That's how I judged the mod after installation. Pre-mod, the rear oscillated quite a bit more, but post mod the rears stabilize almost as fast as the fronts which are undamped.
