Rear Shock Mounts (RSM), BimmerWorld - E30, E36, E46, Z3, Z4 (10mm)

If you have a high-quality performance shock on your car, but you are using rubber or even urethane or upgraded rear shock mounts, you aren't getting what you paid for.

Our Racing Spherical Rear Mounts allow your dampers to precisely control all suspension movement versus typical performance rear shock mounts that allow approximately 1/2" of uncontrolled movement as the upper shaft mount flexes and moves. Average road surface imperfection rate of change means you are giving up a lot of control and potential grip with lesser mounts. You paid good money for those shocks - put them to work with proper mounts!

Our Spherical Rear Mounts have a precision Aurora bearing installed in our billet aluminum carrier. The bearing and spacers are sized for a 10mm shock shaft - the most common for BMW, Bilstein, KONI, and other shocks (see additional info below). The aluminum mount is also slotted to allow for additional tire clearance if needed. The included stainless steel reinforcement plate also makes one-person installation a breeze.

Fits all E30, E36, E46, Z3, and Z4 BMWs. Some convertibles will have to mount the reinforcement plate underneath depending on clearance.

Shock Shaft Note: Most non-adjustable shocks will have a 10mm shaft diameter including OE, Bilstein, KONI non-adjustable. Most adjustable shocks will use a 12mm mount including MCS, KONI Sport, JRZ, etc. This mount is also available with a 12mm bearing (see additional products below).

Gaskets are not included but are recommended.
