BMW Drivetrain Parts for BMW E30 M3 S14 2.3L

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.

The ECS Tuning Center Support Bearing Brace is engineered to improve drivetrain performance and longevity. The factory center support bearing features an internal rubber bushing to reduce NVH (noise, vibration, and harshness) transmission to the cabin. Unfortunately, this material choice falls short when it comes to performance applications. Under extreme load conditions, this bushing is prone to flexing, resulting in driveshaft misalignment. To address the shortcomings of the factory rubber center support carrier design, ECS engineers developed a set of precision-fit, solid rubber bushings that secure tightly around the existing driveshaft bearing. Constructed from 30A durometer rubber, this material eliminates bushing deflection while maintaining minimal noise, vibration, and harshness (NVH). By eliminating deflection, this innovative solution not only improves durability but also ensures a significantly longer service life than the OEM center support bearing—making it an excellent upgrade for aging BMW chassis.

The polyurethane bushings are surrounded by a robust 6061-T6 billet aluminum bracket designed with strength and reliability in mind. This bracket features a split design for hassle-free installation, eliminating the need to remove the driveshaft assembly entirely. To install the ECS Center Support Carrier, simply cut around your existing bearing, remove the factory brace, and clamp on your new bushings and bracket. This user-friendly approach saves time and simplifies maintenance or upgrades. Two stainless steel socket head screws are used to fasten the two-piece bracket, offering corrosion resistance and secure clamping under high torque and stress. This combination of materials and design ensures dependable performance and long-lasting durability, even in demanding applications.

Features & Benefits:

Performance-Designed Bushing Upgrade: 30A durometer rubber is used to eliminate bushing deflection while maintaining a smooth, quiet ride.
Improved Longevity: Solid rubber bushing construction offers a longer lifespan than the thin factory rubber, ideal for enthusiasts looking to eliminate future CSB-related problems.
Billet Aluminum Bracket: The upgraded bushings are encased in a 6061-T6 billet aluminum bracket for enhanced durability and improved performance.
Easy Installation: Both the bushings and the bracket feature a two-piece split design, allowing for seamless installation without driveshaft removal.
Reduce Deflection, Increase Rigidity: Designed with performance in mind, this upgrade eliminates excessive driveshaft movement for improved alignment and efficiency.
