BMW Suspension Bushings & Mounts for BMW Z4 M Roadster S54 (2003-2008)

Clear BMW chassis

Please ensure your correct model is selected

Suspension mounts are designed to absorb the energy of the shocks and springs and isolate road harshness from the chassis. But over time the original rubber mounts will crumble and fail. We have stock mounts and bushings as well as a wide selection of upgraded and heavier-duty for performance street cars. We also offer a full selection of race only bushings and mounts. Simply choose your car below. Included here you will find rear shock tower mounts, front strut mounts, subframe mounts, lower control arm bushings, rear trailing arm bushings, and more.

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 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
