Looking to stiffen up your rear shock mount without going for a solid rear mount? The Polyurethane Rear Performance Strut Mount from IRP will give you the stiffer reinforcement without giving you the typical noise, vibration, and harshness that come with traditional performance strut mounts. The polyurethane also helps with preventing rear shock blowouts, a common problem for stock BMW rear mounts that are paired with stiffer than stock suspension.
The bearing sleeve and poly bushing are built to work with all stock style shocks such as Bilstein and H&R coilover and suspension kits.
Fits the following BMW chassis:
E36 BMW All Submodels except for 318ti
E46 BMW All Submodels
E30 BMW All Submodels
E36 Z3 BMW All Submodels
E85/E86 Z4 BMW All Submodels

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.

This strut and shock mount package covers the front and rear rubber mounts and bushings commonly replaced during a strut and shock install. While you're installing new front struts and rear shocks these are easily installed - there's no additional labor and special tools are not required. Since these pieces are mostly rubber, they dry up and crack over time. Re-using them lead to problems with fitment or noise, and may have safety issues as well. These mounts and pads are the perfect complement to your new shocks to help restore your car's handling and performance.
We sell the basic strut and shock mount package, which includes:
In addition, you can add the front spring pads, front bump stops, front dust boots, rear bump stops, and rear dust boots if needed. But please note that some shocks and coil overs come with all or some of these pieces already. If in doubt, check with your supplier on what is included.
We offer three varieties of the rear shock mounts - OEM, Repair Shop, and HP alum-rubber. We recommend either the Repair Shop or HP mounts because the stock OEM design has a flaw that can lead to premature failure of the mounts. The Repair Shop and HP mounts use a different design that will last longer and the Repair Shop mounts also have a lifetime warranty!
This item fits the following BMWs:
1996-1999 E36 BMW M3
1996-2002 Z3 BMW 2.5 2.5i 2.8 3.0i M Coupe
Want the best performance option in shock tower mounts? IRP has created their pillow-ball rear shock mounts for just this need. These rear shock mounts are designed for use on the track and racing. This set of mounts will help your rear shocks perform the best they can in all conditions. The advantage to using a mount with spherical bearing is that it allows the shock to freely move off axis without side loading the shock shaft like rubber or polyurethane mounts do. Side loading a shock increases stiction and wear which decreases its efficiency. Because these are mounts without an isolator (rubber or polyurethane) to dampen road noise and vibrations we do not recommend them for street cars.
The bearing sleeve and poly bushing are built to work with all stock style shocks such as Bilstein and H&R coilover and suspension kits.
Fits the following BMW chassis:
E36 BMW All Submodels except for 318ti
