ECS BMW Drivetrain Parts

The ECS Tuning Center Support Bearing Brace is engineered to improve drivetrain performance and longevity. The factory center support bearing features internal 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, split polyurethane bushings that secure tightly around the existing driveshaft bearing. Constructed from 30A durometer polyurethane, 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.

• 2 Carrier Pins

Elevate your BMW's shifting experience with Turner Motorsport's precision-designed replacement kit.

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 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 are the two front diff mounts and the rear mount in the cover.

Urethane mounts keep the differential from twisting under load. As torque is put through the driveline it causes anything to twist and move. The differential is mounted to the subframe and the twisting and deflection can be transferred to the rest of the chassis. With a stiffer mount the differential will not deflect as much. This improves seat-of-the-pants feeling to the driver, giving more feedback for smoother power delivery. In theory, there's also more torque being sent to the drive wheels since it's not being used up shifting the diff weight around.

These are tough 88A durometer urethane bushings with a anodized almunum center sleeve, engineered by ECS. This is a set of E36 diff bushings - 1 for the front and 2 for the rear cover. New high-grade hardware is included (the front bolt has a tendency to snap from all that torque twisting!).

Lightweight flywheels have proven themselves to be a worthwhile performance enhancement. But with the quicker throttle response and horsepower improvement comes one serious drawback: flywheel chatter. Without the dual-mass flywheel's rubber isolators, a lightweight aluminum flywheel has more rattle than stock. ECS has designed this flywheel using chrom-moly steel and it weighs almost ten pounds less than the stock DMF but not as extreme as full aluminum flywheels. The steel helps dampen vibration and noise so you get near-factory refinement and most of the benefits of a lightweight flywheel: quicker throttle response, better reliability, and more power to the wheels. Zero-balanced and SFI 1.1 certified (material and design has been independently burst tested to ensure quality and safety). This flywheel requires the E34 M5 sprung hub clutch kit. Choose below from the flywheel only or a complete kit.

Modern flywheels are built with additional components that are designed to dampen and minimize vibrations from the engine and transmission. Weight has increased and reliability has decreased. With additional weight more energy is required for it to move. A lightweight flywheel does away with the dual mass design and its additional mass so more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance. And with a single-mass flywheel the unreliable DMF design is eliminated.

Stock flywheel weight - 25.0lbs
ECS flywheel weight = 16.55lbs

Your rear differential is indirectly connected to your right foot through the engine and driveline, and connected to the seat of your pants through the chassis. Soft factory rubber differential bushings absorb vibrations between chassis and differential, providing comfort and softness in both of these connections.

Enter ECS Tuning's In-House Engineered Performance Polyurethane Differential Bushings. By eliminating the deflection factory rubber bushings permit, the connection between your right foot (and your seat) to the wheels is improved. Removal of this slop allows for crisper power transfer from differential to wheels, which means better throttle control while carving a canyon road, drag racing, sliding the rear end out, or just driving to work. This is achieved without the harshness or vibration associated with delrin or solid differential mounts.

Featuring a tough 88A durometer polyurethane and Black anodized 6061-T6 aluminum Sleeve, our Performance Polyurethane Differential Bushings are more resistant to chemicals, ozone degradation, road salt, and general wear and tear than factory rubber bushings, resulting in a longer service life.

The factory center support carrier features an internal bushing constructed from soft, pliable rubber. While this provides a smooth and quiet ride for standard driving, it falls short in performance-oriented applications where durability and precision are critical. During acceleration, shifting, and under load, the rubber bushing's inherent flexibility allows for excessive driveshaft movement. Over time, repeated stress and wear on the rubber will cause bushing failure, risking poor driveshaft alignment and efficiency. In extreme cases, this failure will cause a constant rotational "clunking" noise, a clear indicator of impending failure.

The ECS Tuning Center Support Bearing Brace is designed to enhance the performance and longevity of your drivetrain. To improve upon the factory design, and to create a performance alternative, our engineers started by designing a set of exact-fit, split low durometer rubber bushings that clamp around your existing driveshaft bearing. Crafted from 30A durometer rubber, our material choice effectively eliminates bushing deflection without causing an increase in noise, vibration, and harshness. By eliminating deflection, this design ensures a longer lifespan than the stock center support bearing, making it a great investment for enthusiasts looking to maintain their aging BMW chassis.

The rubber bushings are encased in a high-strength 6061-T6 billet aluminum bracket, engineered for both durability and performance. Like the bushings, the bracket features a split design, allowing for seamless installation without the need to remove the entire driveshaft assembly, saving time and effort during maintenance or upgrades. To ensure reliable clamping and secure fastening, the bracket is equipped with two corrosion-resistant stainless steel socket head screws. This design simplifies bushing replacement and provides a dependable and sturdy hold, even under high torque and stress conditions.
