Subframe for BMW 3 Series E91 (2006-2012)

A BMWs sub-frame is the heart of the suspension - as the subframe twists and shifts under load all of the suspension mounting points also move. The rear suspension feels loose and lacks precision. As rubber or hydroelastic bushings wear the bushing deflection gets worse. If you have a highly tuned 335i/xi you're putting even more strain on weak bushings. The solution is a stiffer and more durable material. Even BMW has moved to solid mounts on the F10 M5 and F8X M3/M4. These fully solid E82/E90/E92 aluminum mounts have zero deflection - the subframe does not move at all. The rest of the suspension can work as designed and maintain the proper alignment and motion ratios. The driver will notice the difference as the car is more stable and the handling is more precise.

Although we designed these for use in our racecars, they can work on the street so long as the driver can tolerate some additional noise, vibration, and harshness. These mounts are CNC machined in the USA and made with high-grade aluminum. The set is for all four subframe mounts.
