Spec 07-09 BMW 135i/335i/535i SST-Trim Twin Disc Clutch Kit

If you're looking to handle significantly more power in your 2007-2009 BMW 135i, 335i, or 535i, especially if you're pushing the limits of the stock setup, a high-performance clutch like this twin-disc kit from SPEC is a serious consideration. This kit is built to manage the demands of a modified engine that's putting down substantially more torque than it did from the factory. It’s designed to provide a solid connection between your engine and drivetrain, ensuring that power gets to the wheels efficiently without slipping.

This SPEC SST-Trim twin-disc clutch uses a unique dual-plate design. This setup increases the surface area for engagement, which is key to handling higher torque loads. The SST-Trim designation means it's engineered for a smooth engagement, making it more streetable than some other high-performance twin-disc options. It features a sprung center hub design, which helps absorb some of the shock and vibration that can come with a more aggressive clutch, contributing to a more comfortable driving experience. The friction material used is a well-known compound that offers excellent heat resistance and durability, crucial for repeated hard launches or track use. This kit is designed to be a complete solution, replacing the essential components needed for a robust clutch upgrade.

When installing a twin-disc clutch, it's important to ensure all components are properly aligned and torqued according to the manufacturer's instructions. This kit is a significant upgrade, and proper installation is critical for its performance and longevity. You'll want to have the necessary tools and potentially an extra set of hands to make the job go smoothly. This SPEC clutch is a popular choice for BMW owners who are serious about increasing their vehicle's power output and need a clutch that can reliably put that power down.
