Rear Shock Mount (RSM), Powerflex - E30, E36, E46, Z3, Z4 (12mm Shaft)

BimmerWorld View - The stock RSMs in your car are made of soft rubber that gives a minimal connection between your car and the shock that controls its movement over the road. That soft stock rubber also wears quickly and needs replacement after several thousand miles. If the shock can't do its work because of poorly-designed OE bushings, you are giving up significant handling capability. These Powerflex rear shock mounts solve this problem.

Powerflex Rear Shock Mounts are the ideal replacement for the RSMs on your E36, E46, Z3, or Z3 with 12mm-thread rear shocks. Not only will these provide a noticeable improvement in rear shock performance and handling, they're also guaranteed to last a lifetime!

Powerflex has extensive experience in automotive suspension and chassis systems and has combined these skills with advanced polyurethane manufacturing techniques. Durometer is standardized per fitment and location, so you can rest assured knowing the design engineers have selected the optimal urethane hardness for this specific part. The Street option will significantly increase performance with minimal increase in NVH, if any at all, while the Track option is ideal for more serious performance and track use where NVH is less important.

Powerflex copper-based grease is supplied with every bushing set, and they will rarely need re-lubing due to the unique design features built into the material to hold the lubricant.

NOTE: These are designed to fit shock absorbers with 12mm thread. Most adjustable shocks will use a 12mm mount including KONI Sport, JRZ, etc.

Fits all E46/E36/E36 3 Series, plus Z4 and Z3 cars; including M models.

Lifetime warranty.
