These are the best rear shock mounts that we have found for the E30, E36, E46, Z3 & E85 Z4! Featuring CNC-machined billet aluminum mounting base with a replaceable urethane bushing (replacement bushings are just $15 and are changed in minutes!). These mounts are excellent for either street or track because of their low NVH (noise, vibration, and harshness). Plus, the superior design will far outlast the life of stock mounts - maybe even the car itself. You'll never think twice about your shock mounts again! These shock mounts are a direct replacement of the stock mounts so they fit all shocks with the BMW-standard 10mm shock shaft, including all factory and OEM shocks (Boge, Sachs, etc), H&R coil overs, Bilstein shocks and PSS, PSS9, PSS10 coil overs (except the B16 Ride Control Kit). This is sold as a package with new shock mount gaskets, washers, and Nyloc nuts. 
If you are looking for a wider range of camber adjustability in the rear of you car, the IRP Adjustable rear lower control arm is exactly what you need! Built to be much stronger than stock, these rear control arms feature inner monoball bushings and are built of steel, reducing the weight as well. These are perfect for a lowered car or for a track car that needs a greater level of rear adjustment.

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.

Maintaining optimal vehicle alignment is crucial, especially when dealing with challenging road or track conditions. To prevent excess tire wear and ensure precise vehicle handling, turn to the Godspeed Project Rear Toe Arms.
These rear toe arms offer stability at high speeds, thanks to their precise alignment capabilities. Unlike traditional rubber bushings that wear quickly, these arms feature solid spherical bushings for exceptional durability. Their heat-treated ball and hard chrome-plated alloy steel composition guarantee strength and longevity.
Not only do these rear toe arms provide cost-effective performance improvements, but they also offer extended adjustment ranges and versatility. Their solid design enhances road feel, giving you more control and confidence in your BMW's performance.
Please note that realignment is recommended after installation, and these rear toe arms are intended for "Track Use Only" due to the increased road noise and vibration caused by solid bushings.
**For vehicles with stock style springs**
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.

When an E9X is lowered beyond the limits of just lowering springs, the rear wheels toe-in excessively. This excessive rear toe leads to premature wear, that many people attribute to an increase in negative camber. It has become a common belief that an extremely low vehicle will wear the tires wrong as a matter of consequence. It has become standard practice to go as low as you can and proceed to replace your tires every five to ten thousand miles. Whats more is that when the vehicle reaches a certain ride height, the factory arms become maxed out and there is no way to compensate and dial in the proper toe. You're left with an improperly aligned vehicle that is in effect worse off than it was with the stock suspension installed.
This is not only uneconomical but improper and unsafe. ECS Tuning is proud to offer a solution for this problem in the form of Rogue Engineering E9X adjustable rear toe arms. These arms allow for greater toe adjustment on vehicles that have been lowered with a coilover suspension. With the toe set properly the tires can contact the road properly this maximizes grip and minimizes wear.
Features:
The OE thrust plate is more than just a belly panel that covers your oil pan; it plays a crucial role in chassis rigidity, impact safety, and handling dynamics. BMW emphasizes that a vehicle should not be driven or moved without the thrust panel in place due to its importance.
Inspired by BMW's upgrade of the front bumper carrier on the E46 M3 from aluminum to Kevlar during their LCI update, we have made a similar enhancement to the thrust plate with our RKP Carbon Front Thrust Panel.
