Macht Schnell's aluminum bushing kit will breathe new life into aging 1M's and M3's, affixing the car's rear subframe and differential to the chassis. Rubber subframe bushings in the E9x M3 and E82 1M from the factory are soft, and yield under hard driving resulting in ever-changing suspension geometry and alignment specs. By limiting the movement of both the car's subframe and differential, these solid bushings will give the rear of the car a tremendously planted and confident feel.

The E82 and E90/E92 subframes have an inherent weakness in the rear subframe - the mounts are too soft for the power and torque these cars are capable of. The subframe is the heart of a BMW's rear suspension. As torque is transmitted through the differential and axles and as the tires grip the road, the subframe mounts are working to keeping everything in line. That's a tough task to hold when torque is increased with bigger boost (335i) or even mild tweaks (M3). While the M3 subframe mounts are a great upgrade for the non-M chassis these factory BMW Motorsport subframe mounts go one step further.
These Motorsport/Group N rear subframe bushings are a direct replacement upgrade over the stock mounts. They are rubber to conform to the rules of the Group N racing class - so they are still acceptable for street use as long as extra ride harshness can be tolerated. The rear subframe has to come down from the car for these mounts to be pressed in. So now is the perfect time to do other work as well - check out our other Motorsport Race bushings or M3 upgrades.
Price is for the set of 4 mounts.
