Want a race-spec rear shock mount but with the comfort of a factory bushing? This ECS rear shock mount combines the precision and articulation of a spherical bearing with the isolation of urethane bushings. The stainless monoball bearing is lined with PTFE lubricant and suspended in 80A urethane and housed in a hard anodized 6061-T6 aluminum mount. The spherical bearing is a better design than most rear shock mounts because it allows the shock to move and tilt without side-loading the shock shaft (which leads to premature failure of the shock). Most Genuine BMW and aftermarket shock mounts are not designed for shock angles and the stress that track or performance driving will put on the shock shaft. The ECS shock mount is properly designed to handle these loads. The internal bearing is also replaceable - it will be years before you have to replace the entire mount. The ECS mount is fully encapsulated to prevent the common shock mount failure of the stock mount design.
ECS RSM features:
* - the RSM comes with the BMW standard 10mm shock shaft bushings. 12mm is used on some performance shocks and 14mm is used on some true motorsport rear shocks.
BMW used three different spring pads in the E36 E46 3 series, each a different thickness, the thinnest being only 5mm. If they chose to use the thinnest pad on your car, you may end up with a ride height in the rear a little lower than you expected when lowering you car with sport springs. If this is the case, we suggest using these 15mm rear spring pads. These mount on TOP of the rear spring in the E36 and either top or bottom on the E46 or E85 Z4.
