What is the main benefit of a Stage 3+ clutch kit?

A Stage 3+ clutch kit, like this SPEC SF663F-2, offers significantly higher torque holding capacity compared to a stock clutch. This is achieved through a combination of a high-performance friction disc and a heavy-duty pressure plate, preventing clutch slip under increased engine power.

Does this clutch kit come with a new flywheel?

This SPEC clutch kit includes the clutch disc, pressure plate, and release bearing. It does not include a flywheel. It is designed to work with your Mustang's original flywheel, though resurfacing or replacing the flywheel is often recommended during clutch installation.

What should I expect regarding pedal feel with this clutch?

Performance clutches, including this Stage 3+ kit, typically have a firmer pedal feel than the original equipment clutch. This provides a more direct connection to the drivetrain, which is beneficial for performance driving, but it does require a bit more effort to engage.

About this part

Product Details

This SPEC Stage 3+ clutch kit is what you get when you need more holding power for your 2007-2009 Ford Mustang. Inside this box, you'll find the clutch disc, the pressure plate, and the release bearing. This kit is designed to handle significantly more torque than the stock clutch, making it a solid choice if you've modified your Mustang's engine or plan to push it hard on the track or in spirited street driving.

The Stage 3+ designation means this clutch uses a high-performance friction material on the disc, paired with a heavy-duty pressure plate. This combination offers a higher torque capacity, which is crucial for preventing clutch slip under load. While it's a step up in performance, SPEC designs these kits to fit right, meaning you won't need to modify your drivetrain to install it. You can expect a firmer pedal feel compared to stock, which is common with performance clutches, and it's built to be durable for demanding use.

When installing a performance clutch like this, it's always a good idea to inspect your flywheel for wear or damage. If it's not perfectly flat or has hot spots, resurfacing or replacing it will ensure the new clutch performs at its best and lasts longer. This kit is a complete package to get your Mustang's drivetrain back to handling power reliably.
