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

Rubber mounts in any position of a vehicle are usually designed with comfort and longevity in mind leaving performance as a sacrifice. This kind of sacrifice here at Turner just won't do, so we did what we do best and designed a solid monoball mount.
Our engineering team first wanted to tackle the issue with wear found on rubber mounts. Due to their combination of steel, rubber, and low mounting location, these mounts are a direct target for deterioration and failure. As they are positioned out in the open and exposed to the elements, bonded steel and rubber components inevitably hold moisture, separating as the steel bearing begins to rust. Our solution was to offer a rebuildable mount with a Teflon lined bearing for increased durability, combined with a blue anodized body and melonite coated bushing sleeves for corrosion resistance.
The performance side of these mounts is primarily found in the articulation allowed by the bearing. Rubber mounts do not allow for proper free damper movement, hindering shock performance. By eliminating the deflection found in factory rubber mounts and allowing full shock articulation, this solid monoball design eliminates slop and maximizes shock efficiency and performance, allowing for more predictable handling on the street or the track - with almost zero added noise, vibration, and harshness.

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

If you're installing racing rear shocks with a spherical bearing end you will need this adapter mount for the top of the rear shock. Spherical or rod-end bearings are common on race shocks but they are somewhat universal and mounts are not usually included. We designed and engineered these mounts for our E9X M3 and E90 328i IMSA/CTSCC racecars. Our cacing upper shock mount is machined out of aircraft grade aluminum with a tough anodize finish and high grade hardware. Due to the wide variety of spherical bearings and rod-ends found on race shocks, the bushing kit is sold seperately (see chart for bushing sizes).
