Product Details

If you're looking to handle significantly more power in your 2001-2005 BMW 530i, 2001-2003 330Ci, 330i, or 330xi, or the 2001-2002 Z3 with the 3.0L engine and a 5-speed manual transmission, this SPEC Stage 4 clutch kit is a solid option. This kit is built to manage the demands of a high-performance drivetrain, offering a substantial increase in torque capacity over stock components.

SPEC designed this Stage 4 kit with a heavy-duty pressure plate and a multi-plate disc assembly. The multi-plate design is key to handling extreme torque and heat, allowing for a larger friction surface area that dissipates heat more effectively. This setup is ideal for modified vehicles or those that see frequent track use or hard acceleration. While it offers a significant performance upgrade, expect a firmer pedal feel and a more abrupt engagement compared to a stock clutch. The kit includes the necessary components for a comprehensive replacement, ensuring all parts work together seamlessly for optimal performance and durability.

When installing a Stage 4 clutch, it's important to consider that the engagement will be much more direct. This kit is intended for drivers who prioritize maximum power transfer and are comfortable with the characteristics of a high-performance clutch system. Ensure your flywheel is in good condition or consider replacing it at the same time for the best results. This SPEC clutch kit is a well-built solution for those pushing the limits of their BMW's powertrain.
