Has anyone upgraded the RSMs?

Considering BMWs previous history of failed RSMs and the resulting rear clunking, has anyone in the 1er world with aftermarket suspension done this?

I do not see a part no on Rogue's website.

Rear Shock Mount. Common failure point on E36 BMW's. Haven't heard anything on the 1 series RSM though.

lol you are obviously from the e30 world, where the rsm mounts are total shit ! i remember those days with my e30. i havent heard or seen anything about the rear shock mounts failing on e90s or e82's so i think we are fine.

I think the e8x/e9x fleet is still too young to know for sure whether or not the RSMs (or any other suspension components) will be weak links, so I'd hold off making bold statements like that for now.

Frankly, I think the RSM failure mode is overblown, even in E36/E46 land. If you replace the mount when you replace the shock, and replace shocks at a proper interval (~75K) AND you don't regularly drive over potholes on low-profile tires with a slammed suspension the RSMs should never fail catastrophically. If you track or mod, however, all bets are off.

The RSM's on the E82/E9X cars don't have the same weaknesses as the E36/E46 cars. The RSM's are of a completely different design.
