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

**For vehicles with coilover front suspension**

When looking to dial in your steering geometry and alignment for reduced tire where and/or better track handling, the stock suspension is quite limited. To fix this, you can install Camber/Caster plates such as these plates from IRP. Camber/Caster plates allow for adjustment of the top position of the shock's mounting position. These slight adjustments have a huge impact on the stance of the of the wheel when driving straight down the road and when turning into a corner. With simple adjustments, you can increase the grip of the tires in hard turns, improve tread life, or even just make an alignment correction for a vehicle with a lowered ride height. 

The IRP Camber Caster plates are made of an aircraft grade aluminum body, for strength and low weight, with an adjustable mounting plate that utilizes a steel monoball mounting point. This makes the plate resistant to corrosion and prevents deformation even with the stiffest shocks and springs.

Features:

  • Decreased understeer
  • Decreases outside edge tire wear
  • Aircraft Grade Aluminum Construction
  • Steel Monoball and Mounting Sleeves

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.

E36 BMW All Submodels except for 318ti

The subframe is integral to supporting and stabilizing crucial components such as control arms, engines, and transmissions. Bushings located at the junctions between the subframe and the vehicle's body play a vital role. These bushings act to dampen vibrations, ensuring a smoother ride by preventing excessive vibrations from reaching the cabin. They also contribute significantly to maintaining the subframe's stability, thereby keeping all components securely in position.

If you notice increased cabin vibrations or hear unusual sounds like clunks or knocks when driving over bumps, worn-out subframe bushings could be the issue. Replacing them with new bushings not only reduces vibrations but also improves overall stability and performance. This upgrade provides a secure mounting point for critical components like lower control arms, engines, and transmissions, enhancing your vehicle's ride quality and functionality.
