What is included in the SPEC Stage 4 Clutch Kit SP874?

This kit includes the essential components for a clutch replacement: a high-performance clutch disc, a pressure plate with increased clamping force, and a new release bearing. It is designed to be a comprehensive upgrade for your drivetrain.

What kind of driving is this clutch kit best suited for?

The Stage 4 clutch kit is engineered for demanding applications, including track use and street driving with a significantly modified engine. Its increased holding capacity makes it suitable for situations where the stock clutch would slip under heavy load.

Do I need to replace my flywheel when installing this clutch kit?

While this kit includes a new release bearing, it's always recommended to inspect your flywheel during installation. If the flywheel shows signs of wear, such as glazing or deep grooves, it should be resurfaced or replaced to ensure optimal clutch performance and longevity.

About this part

Product Details

If you're pushing your 2005-2011 Porsche Boxster (6-speed) hard on the track or looking for a significant boost in holding power for a modified engine, a Stage 4 clutch kit like this one from SPEC is a solid choice. This kit is built to handle more torque and abuse than the factory clutch, making it ideal for drivers who demand more from their drivetrain. It's a comprehensive upgrade designed to give you confidence when you're really putting the power down.

This SPEC Stage 4 kit includes a high-performance clutch disc, a robust pressure plate, and a new release bearing. The clutch disc features a sprung hub design with a high-density friction material, offering excellent engagement and durability under demanding conditions. The pressure plate is engineered for increased clamping force, ensuring the clutch can effectively transfer power without slipping, even when dealing with significantly increased engine output. This combination is what allows the Stage 4 kit to hold substantially more torque than a stock clutch, making it a popular choice for Boxster owners who have upgraded their engine's performance.

When installing a clutch kit of this caliber, it's important to have the right tools and follow the manufacturer's recommended procedures. This kit is designed as a direct replacement for your factory clutch assembly, meaning it fits right into the existing transmission bellhousing. Ensure your flywheel is in good condition or replace it if necessary, as a worn flywheel can impact clutch performance and longevity. This SPEC clutch kit is a well-built component that will make a noticeable difference in how your Boxster handles power, especially during spirited driving or track events.
