Clear BMW chassis

Please ensure your correct model is selected

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

This brass clutch pivot pin is an upgrade over the stock plastic pivot pin. The brass pin will last a lot longer than the plastic piece and may save you time and hassle later on. The original plastic pivot pin is known to fall out, snap, or just wear out over time. At the least you get a very annoying squeak every time you depress the clutch. In a worse case scenario, the clutch fork won't be able to push on the throw-out bearing and your clutch will be useless. The only time to replace the clutch pivot pin is when the transmission is removed, so this brass upgrade can be installed during clutch replacements or a rear main seal service.

Worn rubber differential mounts will lead to the differential twisting and shifting around in the rear subframe. Not only will this be noisy but it's bad for driver confidence and bad for the chassis as well. Even on fresh rubber bushings the differential has deflection and twist, especially if the car has been modified for more torque. Since the differential is centrally mounted in the rear subframe, with all suspension mounts interconnected, a differential with too much deflection will affect handling and could even damage the rear subframe.

These 88A urethane E46 M3 diff mounts are much stiffer than stock but still not as solid as our Turner aluminum/Delrin bushings. This set will resist twisting much better than the stock rubber mounts. Included is the front diff mount and two rear mounts in the cover.

Revitalize your driving experience with ECS Tuning's In-House Engineered Performance Polyurethane Differential Bushings. Say goodbye to soft factory rubber bushings and their deflection. These innovative bushings provide a substantial improvement in the connection between your right foot, the chassis, and the wheels. The outcome is a crisper power transfer from the differential to the wheels, resulting in enhanced throttle control for various driving activities. Notably, these polyurethane bushings achieve these benefits without the harshness or vibration often linked to delrin or solid differential mounts.

Manufactured using a robust 88A durometer polyurethane and a black anodized 6061-T6 aluminum sleeve, these bushings offer superior resistance to chemicals, ozone degradation, road salt, and general wear and tear. This translates to an extended service life.

Shifter slop is a common complaint among all BMW models. Some of that play comes from the bushings where the shifter carrier mounts to the transmission. The original rubber carrier bushings don't last very long and when they get too soft the shifter flops around. These Delrin bushings have almost no deflection and will last much longer than the factory rubber, giving you precise shifting for many years.

Note: this is only one part of the shift linkage and there may be other components that need replacing to improve shifting feel.

New carrier bushing pins are included.
