ECS BMW Drivetrain Parts

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.

Whether you're chasing lap times or elevating your daily driving experience, the ECS S54 Performance Clutch Kit & Lightweight Flywheel is the upgrade your BMW deserves. Single Mass Flywheel Conversion: Audible chatter from the transmission after installation is considered normal. As with most single mass flywheels, there is less dampening in the flywheel to reduce "gear noise." This chatter noise may be more present when the transmission fluid temperatures are hotter and may be intensified by other modifications. Most gearboxes will experience some chatter noise at hotter temperatures. Please be advised that this noise will disappear once the clutch pedal is depressed. This symptom may be lessened by adjusting transmission fluid weight, turning off electrical/driveline consumers (A/C, High Beams, ETC.), and by raising the RPM slightly.

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.

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.

Driveshaft Center Support Carrier - Early E30 318, 325

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.

FEATURES

Exact-fit bushings are made from 30A durometer rubber to eliminate bushing deflection while maintaining a smooth, quiet ride.
Solid fill rubber construction offers a longer lifespan than flimsy factory rubber, ideal for enthusiasts looking to eliminate future CSB-related problems.
Bushings are encased in a 6061-T6 billet aluminum bracket for enhanced durability and improved performance.
Both the bushings and the bracket feature a two-piece split design, allowing for seamless installation without driveshaft removal.
Designed with performance in mind, this upgrade eliminates excessive driveshaft movement for improved alignment and efficiency.

The factory dual-mass flywheel in your MINI N14 was built with comfort in mind—absorbing drivetrain vibrations and smoothing shifts—but at the cost of performance. Weighing in at a hefty 28.3 lbs., the OEM flywheel adds excessive rotational mass, dulling throttle response, slowing acceleration, and complicating precise rev-matching. Worse yet, it's known to be unreliable in modified or tuned setups and expensive to replace when it fails.

This single-mass design from ECS Tuning weighs just 18.8 lbs. It cuts nearly 10 lbs. of rotational weight to significantly enhance throttle response, acceleration, and overall driving feel. Built for durability and spirited driving, it's the ultimate upgrade for enthusiasts who want to make the most of every gear change.

Key Features:

Precision CNC-machined from 4140 HT Chromoly Steel: Ensures outstanding toughness, consistent wear, and long-term durability.

Heat Treated and Tempered: Achieves HRC 28-32 for improved strength, stress relief, and dimensional stability—even at elevated temperatures.

Black Oxide Coated: Resists corrosion for long-lasting protection and a professional finish.

Precision Balanced: Exceeds OEM standards (G16, 175 g-mm) to ensure smooth, safe operation at all RPMs.

SFI 1.1 Certified: Tested and approved for extreme use—track or street.

Direct Fit for OE N14 Clutch Kits: Maintains compatibility with factory-style components for hassle-free installation.

Eliminate power-robbing rear-end flex and upgrade your E36’s dynamic handling with the Turner Motorsport Track-Spec Differential Bushing Package. On the track or aggressive backroads, factory rubber differential mounts distort heavily under load, delaying throttle response and compromising rear alignment geometry. This complete package locks down the front and rear differential mounting locations, routing torque directly from your right foot to the pavement for maximum acceleration and predictable corner exit.

Engineered for drivers who demand race-bred chassis feedback without the unrefined harshness of solid metal mounts, this package equips your E36 with a heavy-duty polyurethane upgrade. Up front, a stiff 95A polyurethane bushing is anchored by a high-strength M14x1.5 Grade 12.9 bolt, overcoming the notoriously weak factory M12 bolt setup to survive high-RPM launches and severe track abuse. Out back, 88A polyurethane rear bushings stabilize axle load shifts to keep the rear end planted through turn-in and high-G cornering. Lightweight, black-anodized 6061-T6 aluminum inner sleeves deliver structural integrity in severe racing environments.
