What is the difference between this Stage 2 disc and a stock clutch disc?

This Stage 2 disc is designed with a unique friction material that provides improved engagement and a higher torque capacity compared to a standard factory clutch disc. It's built to handle more power and offer a crisper feel.

Do I need to buy anything else to install this clutch disc?

Yes, this is the clutch disc ONLY. It is designed to be a replacement for the disc in the SPEC ST633H clutch kit. You will need the corresponding SPEC pressure plate and release bearing, which are typically sold as part of the complete ST633H kit.

What is the break-in procedure for this clutch disc?

Always refer to the manufacturer's installation instructions for the specific break-in procedure. Generally, it involves a period of light driving with minimal hard acceleration or slipping to allow the friction surfaces to mate properly.

Product Details

When you're looking to get more performance out of your manual transmission vehicle, a clutch upgrade is often the next step. This SPEC Stage 2 clutch disc is designed as a replacement for their ST633H clutch kit, offering an improved engagement feel and a higher torque capacity than a stock clutch. It's a well-built component aimed at drivers who want their clutch to handle more power and respond more crisply.

This disc features a unique material compound that balances grabbing power with smooth engagement, making it suitable for daily driving while still being able to handle spirited driving or track use. The design focuses on providing a solid connection between the engine and the transmission, ensuring that power is transferred efficiently. It's a direct replacement for the disc in the ST633H kit, so if you already have that kit installed and need to replace just the disc, this is the part you'll need.

Remember, this is the clutch disc only. If you are installing this as part of a new clutch job or replacing a worn-out ST633H kit, you'll also need the corresponding pressure plate and release bearing, which are typically included in the full ST633H kit. Ensure you follow the manufacturer's installation instructions for proper setup and break-in.
