Insert, Rr Sub Set, E9X BMW

The 034Motorsport Billet Aluminum Rear Subframe Mount Insert Kit for E9X BMW models is designed to limit movement in the factory rear subframe mounts. This kit improves the responsiveness of the rear suspension and differential by filling voids in the four factory mounts and limiting vertical movement, eliminating associated slop.

These billet aluminum parts will not pack and wear over time, offering a lasting performance improvement. The kit provides a more refined, connected driving experience, especially when driving at the limit. NVH (noise, vibration, and harshness) transfer to the cabin is rated as None to Low.
