BMW Drivetrain Parts for BMW 5 Series E34 (1987-1995)

Enhance your car's performance with ECS Tuning's polyurethane transmission mounts, designed for both street and track applications. These mounts are engineered to withstand high torque and forced-induction scenarios, eliminating concerns about torn mounts and providing a more engaging driving experience. Although polyurethane may introduce some additional NVH (Noise, Vibration, Harshness), its exceptional durability, wear resistance, and resistance to water, oil, and grease make it the perfect choice for performance enthusiasts. ECS Tuning offers two durometer options to match your driving style, along with a comprehensive DIY installation guide, ensuring a complete solution for your transmission mount requirements.

Key Features:

• Minimized transmission movement, reducing the risk of mis-shifts and over-revs.
• Made from high-quality polyurethane bonded with 304 Stainless Steel.
• Enhanced driving experience for both street and track enthusiasts.
• Two durometer options available: 80A for race applications and 70A for daily driving (ES#2859359).
• Replaces weak OEM mounts.

Stock rubber flex discs allow for a slight amount of give, especially under heavy acceleration and, depending on the amount of force applied, could potentially tear or split. This slight flex/give can prevent instantaneous transfer of force to the wheels, making accelerations unpredictable, or even lead to your vehicle being stuck on the side of the track. To combat this, IRP's Performance Flex Disc was developed. Made of CNC machined aluminum, this flex disc won't actually flex, and the polyurethane bushings will only provide a enough give to dampen some vibrations and prevent damaging the transmission. This is perfect for high torque applications such a drag cars and dedicated track cars that want immediate response and long term reliability.

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 flywheel and upgraded clutch kit for improved throttle response, acceleration, and clutch feel - the perfect setup for daily-driven vehicles with up to 400 Ft/lbs of torque.

This performance clutch and flywheel kit utilizes an upgraded ECS E34 M5 clutch kit with their in-house engineered flywheel to fit all M5x and S5x motors with a 5-speed transmission. By eliminating the dual-mass flywheel and replacing it with a single-mass you are able to eliminate the slack and extra weight of the flywheel for a quicker throttle response and acceleration. Their upgraded clutch kit utilizes all the best features of the original M5 clutch with an upgraded pressure plate and clutch disc, with the new clutch you have a better, more engaged clutch pedal feel, engagement, and longevity.

Whether you're replacing a worn-out clutch or upgrading for increased power handling, this E34 M5 clutch and flywheel kit offers a reliable solution for enhanced pedal feel, power capacity, and overall driving satisfaction.

Paired with a modified geometry flywheel, the E34 M5 style clutch is ideally suited for most E36, E46, and others using the same powertrain. It checks all the boxes for essential clutch replacement features. While some aftermarket options may address slipping issues and worn-out clutches, they often sacrifice pedal feel, providing little to no resistance. A soft clutch not only kills the driving experience of your BMW but also reduces confidence when pushing the car to its limits.

On the contrary, you might be in the market for an upgraded clutch to handle your modified engine/forced induction builds. You go from an OE or aftermarket clutch option that has a lackluster and soft pedal feel to the complete opposite side of the spectrum, a very stiff clutch that grabs like an on-and-off switch making the clutch a pain almost undrivable on the street resulting in your favorite car turning into your least favorite car to drive.

The E34 M5 clutch and flywheel kit balances performance with practicality, ensuring a satisfying driving experience whether you're maintaining your BMW or preparing it for increased power demands.

A sloppy shifter is one of the common complaints of older BMWs. In addition to the shifter linkage the transmission mounts contribute to rough and clunky shifting. BMW transmission mounts are rubber and get softer over time. This allows the transmission to dance around which changes the geometry of the shift linkage and could make it harder to shift. These urethane transmission bushings are stiffer than the stock rubber mounts and won't let the transmission shift around as much. The round design also has more surface area than the stock mounts which helps spread the load. Because the urethane is stiffer, expect more vibration to make its way into the shift lever area. Engine motor mounts should also be considered as a cause for driveline vibration, transmission movement, and poor shifting. Consider replacing your motor mounts at the same time as your tranny mounts.

Price is for the pair of transmission mounts with hardware.

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.
