Spec 07-10 BMW 335i/135i Stage 3+ Clutch Kit *Requires SB53A-2 Flywheel*

The SPEC Stage 3+ clutch kit uses a high-performance sprung organic friction disc, a solid iron pressure plate, and a robust release bearing. This combination is built to handle significantly more torque than the factory clutch, making it a solid choice for modified BMWs that see spirited driving or track use. The sprung hub design on the organic disc helps absorb some of the shock and vibration, offering a more comfortable engagement than a solid hub disc, while still providing excellent durability for higher power applications.

This Stage 3+ kit is engineered to be a direct replacement for the stock clutch assembly, though it's important to note that it requires the SPEC SB53A-2 flywheel, which is sold separately. The solid iron pressure plate offers a strong clamping force, ensuring that power is reliably transferred to the drivetrain even under demanding conditions. The organic friction material provides a good balance of grip and drivability, making it suitable for daily driving when paired with the appropriate flywheel and driving style, while also holding up to repeated hard launches and aggressive gear changes.

When installing this clutch kit, ensure you have the necessary tools and follow the manufacturer's recommended procedures. Because this is a performance-oriented upgrade, you may notice a firmer pedal feel compared to the stock clutch. It's also a good idea to inspect your pilot bearing and rear main seal while the transmission is out, as these are common maintenance items that are easily addressed during a clutch replacement.
