BMW Drivetrain Parts

If you've ever bled the clutch hydraulic system on your BMW, you know how frustrating it can be. Designed with both DIY enthusiasts and professional technicians in mind, our clever tool simplifies one of the most notoriously annoying steps in clutch service.

Crafted from high-quality aluminum and finished in a durable black anodized coating, our clutch slave cylinder bleeder tool is built to last. Its function is simple: the adjustable piston rod applies controlled pressure directly to the clutch slave cylinder’s piston, compressing it and reducing its internal volume. By minimizing the amount of air trapped inside the cylinder, bleeding becomes faster, cleaner, and far more effective—no more endless pedal pumping or inconsistent clutch feel. The result is firm, consistent clutch pedal engagement and a smoother overall driving experience, all achieved with less time and effort underneath the car.

FEATURES & BENEFITS

Simplifies bleeding the BMW clutch hydraulic system by reducing trapped air in the slave cylinder Eliminates excessive pedal pumping and inconsistent clutch feel Helps achieve firm, consistent clutch pedal engagement Crafted from high-quality aluminum for strength and longevity Durable black anodized finish resists wear and corrosion Designed for both DIY enthusiasts and professional technicians PRODUCT DEVELOPMENT

Our Clutch Slave Cylinder Bleeder Tool was designed, engineered, tested, and quality inspected by our Research and Development team at Turner. Nothing but the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

Put an end to drivetrain flex and destructive wheel hop. The S58 engine is an absolute torque monster, especially once you start tuning and turning up the boost. While aggressive launches and heavy acceleration are the best parts of owning these vehicles, the factory rear differential mounting wasn't designed to handle that kind of abuse.

The OEM soft rubber bushing allows excessive differential twist and flex under load. This deflection transfers massive, uneven force directly to the factory mounting bolt, leading to bending or catastrophic snapping. Our upgrade replaces that weak link, locking down your drivetrain to ensure every bit of horsepower reaches the pavement safely.

The factory BMW S65 dual-mass flywheel is engineered with comfort in mind, catering to the luxury-oriented expectations of the brand’s driving experience. Its design focuses on dampening drivetrain vibrations, smoothing out gear transitions, and minimizing harshness during operation. However, this refinement costs valuable performance. The dual-mass flywheel adds a substantial 27 lbs of rotational mass to the drivetrain, which significantly hinders throttle response and makes rev-matching feel sluggish and disconnected. Moreover, dual-mass flywheels are notorious for being a weak link in modified or high-performance builds and can prove costly to replace when they inevitably fail.

Our Single-Mass Lightweight Flywheel Conversion addresses all of these shortcomings with a purpose-built, lightweight, single-mass design that prioritizes performance. Weighing in at only 19 lbs., this design significantly reduces rotational mass, allowing your S65 to achieve its true motorsport potential!

Features & Benefits:

Precision machined from 4140 HT heat-treated chromoly steel for exceptional toughness, even wear properties, and increased durability.
Material quality promotes even wear across the entire friction surface, prolonging component lifespan.
Heat treated to HRC 28-32, tempered to relieve stress and improve dimensional stability.
Hardness improves component wear characteristics.
Black oxide coated for corrosion resistance on non-friction surfaces.
Precision balanced to exceed OEM specification (G16 spec to 175g-mm).
Specifically designed to work with S65 OE-architecture clutches.
Optimized step height maximizes clutch clamp load and offers a prolonged service life.
Performance:

8 lbs. lighter than the factory BMW flywheel!
OEM Dual-Mass: 27 lbs.
Turner Motorsport Single-Mass: 19 lbs.
Faster revs
Improved throttle response and acceleration
Allows for a more engaging driving experience and delivers a feeling of direct connection
Installation:

Flywheel Hardware: For added peace of mind, apply Blue or Orange Loctite when installing factory flywheel bolts that do not come with pre-applied threadlocker.

BMW E30 325i/iS DSSR (187mm) - Turner Motorsport is the ultimate solution to eliminate shifter slop, providing tighter and crisper shifts for your BMW. Developed in collaboration with Rennline, this Dual Shear Selector Rod (DSSR) is designed to significantly reduce flexibility in the selector rod, ensuring a more precise and responsive shifting experience.

TURNER MOTORSPORT DOUBLE ADJUSTABLE SHORT SHIFT KIT

BMWs have historically been plagued by very long throw shifters from the factory - luckily, we've developed the solution. Our short shifter system is height- and throw-adjustable, offering up to a 52% reduction in throw over stock. Double adjustability enables you to find the sweet spot that will make you excited to drive your car again. Installation of this kit is also of the easiest to tackle. Compared to the competition, a custom bearing cup allows for easy installation from inside the car (on applications that use the stock shifter arm).

Benefits:

Adjustable between a conservative short throw to ultra short throw Ultra crisp shifter feel - quicker, more precise shifts More engaging driving experience Adjustability:

Independently adjustable knob height 22mm adjustment range to fine-tune shifter throw and feel. Note: knob height also affects throw reduction to some degree Independently adjustable shifter throw Adjustable by raising and lowering the lower lever position relative to the pivot ball. Note: ball position also affects knob height by ~10mm range Combined total throw adjustment range ​32 to 52 % reduction in throw over stock E36 shifter. A throw adjustment can be done in the car without removing the shifter DSSR (109MM) - E36 420G

Like all OEM selector rods, the factory part uses single-shear attachment, allowing for deflection within the shifter linkage. The result? Vague, imprecise gear selections that detract from your overall driving experience. The dual-shear selector rod (DSSR) design spreads the torsional force of gear selections across the selector rod joint, reducing deflection for increased precision. Our DSSR is precision-machined from durable 304 stainless steel to further reduce deflection and resist corrosion.

Features:

Provides a more positive feel in the shifter by reducing play in the linkage due to minimized deflection Manufactured from 304 stainless steel for superior corrosion resistance and durability Replacement for 25112228055 (European E36 M3 Evolution) HEAVY-DUTY SHIFTER ARM - E36 420G

To cater to the six-speed swap E36 community, we designed a direct replacement and upgrade for the unavailable, 420G-specific shifter arm. Precision-machined from 6061-T6 billet aluminum and clear anodized, this replacement carrier is durable, lightweight, and built to last. It is dimensionally identical to the OEM carrier, ensuring compatibility with the OEM shift carrier bushing, shift lever, and Turner Motorsport Double-Adjustable Short Throw Shifter Kit.

Features:

6061-T6 billet aluminum construction provides excellent durability and longevity Mil-spec clear anodized for superior corrosion resistance Dimensionally identical to its OEM counterpart, ensuring compatibility with all factory shifter components POLYURETHANE SHIFTER ARM BUSHING

This shifter bushing is designed to remove the shifter play caused by an old, failed rubber shifter bushing. Manufacturing the bushing from polyurethane instead of rubber reduces the amount of stretch caused by the moving part through the bushing. This maintains the direct crisp feel from your shifter assembly. When your OE shifter arm bushing begins to fail, you will notice slop in shifting, potentially making it easier to miss gears, and it often causes an obvious vibration and movement from the engine RPMs.

Features:

Corrosion-resistant 304 stainless steel mounting sleeve with bonded 70a polyurethane Stiffer bushing results in a crisper shifter feel and a more engaging driving experience.
