One of the best places to put as stiff a bushing as possible without ANY NVH is the rear subframe. We recommend the 75D mounts for street or track/race use! Replacing the spongy rubber mounts improves the cars feel a HUGE amount!. 

Revshift polyurethane rear subframe bushings completely replace the oem rubber bushings on the E46 (323, 325, 328, 330, M3, Z4). These bushings stiffen the subframe improving the vehicles handling capabilities.
