Spec 07-09 BMW 135/335/535 Super Twin PT-Trim Semi-Metallic Puck Clutch Kit w/Alum Flywheel

SPEC is known for making well-built performance clutch components, and their Super Twin PT-Trim clutch kit is a prime example of that. This kit is designed for 2007-2009 BMW models like the 135i, 335i, and 535i, offering a significant upgrade for those looking to handle more power or simply replace a worn-out clutch with something more robust. It features a semi-metallic puck design, which is a popular choice for its strong engagement and ability to handle high torque loads without slipping.

The PT-Trim designation means this clutch is built for a more aggressive engagement, providing a solid connection between the engine and the drivetrain. This is paired with an aluminum flywheel, which is notably lighter than a stock steel flywheel. This weight reduction helps the engine rev more freely, contributing to improved throttle response and a more dynamic driving feel. The twin-disc setup means there are two clutch discs working together, distributing the load and heat over a larger surface area. This not only increases the torque capacity but also helps with heat dissipation, making it a solid option for demanding driving conditions.

When installing a twin-disc clutch like this, it's important to follow the manufacturer's instructions carefully, as the setup can be more involved than a single-disc clutch. The kit includes the necessary components for the clutch system itself, but you'll want to ensure your pilot bearing, throw-out bearing, and any other related drivetrain components are in good condition before installation. This SPEC clutch kit represents a substantial upgrade for your BMW, offering improved performance and durability for spirited driving.
