BMW Performance Clutch Kits & Parts

Advanced Clutch Technology (ACT) designs, engineers and develops products by leveraging decades of track and performance street experience. Advanced CAD, FEA simulation, and CAM tools help ensure highly optimized performance, reliability, and repeatability. These key advantages are produced by combining the best engineering and design methodologies with the latest in materials and manufacturing techniques.

ACT clutch kits stand unequaled in terms of consistent pedal feel, high torque capacity, long wear life and durability. In-house manufacturing is critical in tuning components specifically to each individual application while maintaining the predictable ACT pedal feel across the entire catalog.

This clutch kit features an Xtreme pressure plate, a G6 racing clutch disc, and an XACT Streetlite Flywheel.

Their Xtreme pressure plate offers a 50-120% clamp load increase, moderate to heavy pedal feel, and is recommended for high performance street and racing applications. All diaphragms went through a four stage heating process for increased strength and unparalleled performance.

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 4-pad disc. Its material composition is high quality, ceramic friction materials and a heavy duty torsional dampening springs that are rate 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.

The final main component is the XACT Streetlite Flywheel. This option is the most popular thanks to it versatility for street driving and drag/track style racing, its lighter weight for increased throttle response, and its single mass design.

Stage 3 Daily Clutch Kit for BMW

Upgrade your BMW's clutch system with this Stage 3 Daily Clutch Kit, designed for high-performance vehicles seeking OEM-like start performance. Engineered with a Race Engineered (SS) pressure plate, this kit offers a significant load increase over stage 1 and 2 pressure plates, providing enhanced durability and performance. Experience a 20%-25% increase in pedal effort, ensuring precise control during acceleration. The discs are equipped with heat-treated wear-resistant hubs, drive plates, and springs for optimal load transfer and reliable operation. The sprung centers and marcel fin on the disc deliver dual dampening effects for smooth starts, similar to OEM performance. With a Performance Organic friction material, this kit enhances torque and RPM capability while maintaining low operating temperatures to minimize wear and glazing.

• Suitable for daily driving, spirited street, and occasional track use
• Rated to hold up to 500lbs/ft of torque
• Features a sprung hub clutch compatible with SouthBend Single Mass Flywheel (ES4140474)

MINI R52 R53 Lightweight Aluminum Flywheel (12lbs) enhances the performance of the MINI with its precision engineering and lightweight design. This flywheel, manufactured by SPEC, is tailored for specific driving environments, making it ideal for both daily driving and high-performance applications.

• Lightweight Design: Weighs approximately 12 lbs, reducing rotational mass for quicker engine response and improved acceleration.
• High-Quality Construction: Made from premium steel and aluminum, ensuring durability and a flat seating surface for the clutch.
• Precision Engineering: Manufactured to a .001 machine tolerance for smooth rotational qualities and perfect balance.
• Performance Upgrade: Essential for converting from OE dual mass to single mass when used with SPEC Design clutch kits.
• Versatile Application: Suitable for various driving habits and racing or high-performance setups.

This is the stock twin mass flywheel for the N55 engine used in the E82 135i, E9X 335, F3x 335/435, and F10 535i. It's manufactured by OEM supplier LuK. Sachs recommends a new dual mass flywheel (DMF) on every other clutch replacement. There are several indicators for replacing the flywheel: damage to the clutch contact plate (from a severely worn clutch disc), grease leaking from inside (overheating), build-up of clutch material on the contact plate (excessive slipping and overheating), and failure of the internal damping system.

The dampening system uses rubber or coil springs to absorb driveline vibrations. Through age, excessive heat, and aggressive use the rubber loses its resilience and the metal springs lose their strength and become brittle. If the clutch and flywheel have become overheated the internal grease may break down as well. A DMF failure can be massive and catastrophic, not to mention dangerous as bits of metal and rubber fling themselves through the transmission bellhousing. Heat and aggressive driving will accelerate the wear so race and track cars should have their stock flywheels replaced at regular intervals or with any new clutch. Even normal street cars should plan for a new flywheel if it has high mileage.

DMF wear can only be checked with the transmission and clutch removed. If you can rotate the outer flywheel more than 20mm in either direction then it should be replaced.

A new pilot bearing (roller bearing) is included, pre-installed in the flywheel hub.

This item fits the following BMWs with the single turbo N55 engine and manual transmission:
2011-2012 E82 BMW 135i
2011 E90 BMW 335i 335xi 335i xDrive - Sedan
2011-2013 E92 BMW 335i 335xi 335i xDrive - Coupe
