Please ensure your correct model is selected

These heavy-duty clutch kits use aluminum lightweight flywheels with sport clutch components to give your clutch the grip and clamping force it needs to cope with high torque upgrades. Our kits were developed through racing programs by companies affiliated with our own race team - JB Racing, Sachs Sport, OS Giken, and UUC Motorwerks. JB Racing is the leader in aluminum lightweight flywheel upgrades. They are direct replacements for the stock dual-mass flywheels with steel contact surfaces and computer balanced to 14,000 RPM. JB has partnered with Sachs to spec sport/HD clutch discs and pressure plates that work seamlessly with their aluminum flywheels. The result is a clutch/flywheel upgrade package that functions a lot like the original clutch combo with near-stock levels of effort and engangement but with a much higher torque capacity. Don't let the clutch be your weak link in a highly tuned car!

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.

Introducing the Turner Motorsport Performance Lightweight Flywheel! 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. We have designed our brand new flywheel using Chromoly steel, cutting weight by almost ten pounds vs the stock Dual-Mass Flywheel. 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). 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 are 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. With a single-mass flywheel, the unreliable Dual-Mass Flywheel design is eliminated. Features: Precision machined from 4140 HT heat-treated Chromoly steel for exceptional toughness, even wear properties, and durability. Material quality promotes even wear across the entire friction surface Heat treated to HRC 28-32, tempered to relieve stress and improve dimensional stability and elevated temperatures Hardness improves wear characteristics Black oxide coated for corrosion resistance on non-friction surfaces. Precision balanced to exceed OEM specification (G16 spec to 175g-mm). SFI 1.1 tested and certified to ensure safe operation under extreme operating conditions SFI 1.1 specifies minimum material properties and requires a 3rd party lab certification test, spinning the flywheel to 1.5x redline for 1 hour to ensure the flywheel will not burst. Specifically designed to work with S54 architecture clutches Step height designed to optimize clamp load and maximize the usable range of clutch wear for a long service life To get the most out of this flywheel, we have paired up with ACT Clutch to develop four clutch kits that will fit your needs! ACT Clutch has proven time and time again that they offer some of the best clutches on the market, offering both high quality and phenomenal performance, creating a perfect pairing for Turner's flywheel. BM9-HDSS - Heavy Duty (HD) Pressure Plate with Sprung Center Street Disc (SS) BM9-HDG6 - Heavy Duty (HD) Pressure Plate with Sprung Center 6-Puck Race Disc (G6) BM9-XTSS - Xtreme (XT) Pressure Plate with Sprung Center Street Disc (SS) BM9-XTG6 - Xtreme (XT) Pressure Plate with Sprung Center 6-puck Race Disc (G6) To better understand which clutch kit you need, let's break down what components are available to choose from: Heavy Duty Pressure Plate: ACT's Heavy Duty pressure plate offers a 20-50% clamp load increase over the stock S54 pressure plate, stock to moderate pedal feel, and can be used for either street or racing applications. All diaphragms go through a four-stage heating process for increased strength and unparalleled performance. Xtreme Pressure Plate: Xtreme pressure plate offers a 50-120% clamp load increase over the stock S54 pressure plate, moderate to heavy pedal feel, and is recommended for high-performance street and racing applications. All diaphragms go through a four-stage heating process for increased strength and unparalleled performance. Sprung Center Street Disc: ACT's most popular sprung clutch disc. Its material composition is high quality, organic friction materials with high copper content for better heat transfer, and a steel-backed lining for great burst energy strength. It has an increased torque capacity and is better for faster shifting with its reduced marcel. This disc offers a long life span and quiet operation with increased strength and reliability. Sprung 6-Puck Racing Disc: The G6 clutch disc is a sprung, 6-pad racing disc that is recommended for high horsepower street and race us and is better at handling high heat than the street disc. Its material composition is high quality, ceramic friction materials and a heavy-duty torsional dampening springs that are rated for this clutch disc's size and expected uses. It has an increased torque capacity and is better for faster shifting with its low weight and inertia. Being a racing disc, it has good durability and its ceramic composition allows for high heat tolerances. It also has a fast, aggressive engagement in comparison to standard street-use clutch discs.
