BMW Drivetrain Parts for BMW Z3 (1996-2002)

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 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.

Features & Benefits:

Performance-Designed Bushing Upgrade: 30A durometer polyurethane is used to eliminate bushing deflection while maintaining a smooth, quiet ride. Improved Longevity: Polyurethane construction offers a longer lifespan than 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. Kit Includes:

ECS Driveshaft Center Support Bushings ECS Driveshaft Center Support Carrier (2) Stainless Steel Hex Head Screws (2) Flange Nuts (26117574872) Medium Strength Threadlocker (0.5ml) Installation Instructions:

ECS has provided a detailed, start-to-finish installation guide to aid in the process of installing your new Driveshaft Center Support Carrier.

Crisper shifts
Improved throttle response
Improved acceleration (We measured a .4s decrease in 0-60 times on an otherwise-stock E36 328i!)
Lower replacement cost
Hardened 4140 Chromoly Steel for excellent engagement feel and wear resistance; zinc plated for corrosion resistance
Designed for use with any E34 M5 pressure plate and clutch for OE-type clutch feel
Sprung-hub clutch disc to eliminate chatter at idle and reduce driveline shock loading
Weighs in at just 16.5lbs!
SFI tested and certified to ensure safe operation under all conditions
Includes ECS performance flywheel, clutch kit with throwout bearing, pilot bearing and all flywheel and pressure plate hardware
Why is SFI testing and certification important?

The SFI Foundation, Inc. (SFI) is a non-profit organization established to issue and administer standards for the quality assurance of specialty performance and racing equipment. SFI certification indicates a flywheel has been certified using industry-standard SFI Spec 1.1 standards by an independent testing body to ensure quality of both design and materials for flywheels utilized in competitive motorsports.

Having successfully passed SFI certification, this flywheel has an individual SFI serial number found in a laser etching, and on an affixed sticker. This certification means the ECS-engineered flywheel is safe and reliable during the rigors of competitive racing; it's also safe and reliable for years and years of street use.

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
