Spec 12-13 Subaru BRZ Stage 4 Clutch Kit

This SPEC Stage 4 clutch kit is built with a sprung, multi-plate design, featuring a carbon-fiber friction surface. This setup is engineered for vehicles that see a lot of hard use, like track days or serious performance street driving, where the stock clutch just won't hold up. It's a significant upgrade over the factory unit, designed to handle much more power and torque without slipping.

The multi-plate configuration, combined with the carbon-fiber friction material, allows for a larger surface area to engage with the flywheel and pressure plate. This means more clamping force and better heat dissipation, which are crucial when you're putting a lot of stress on the drivetrain. The sprung hub design helps to dampen vibrations and reduce drivetrain shock, making it more manageable for daily driving than a solid hub setup, though it will still be firmer than stock. This kit is a solid choice if you've modified your engine for more power or plan to, and need a clutch that can keep up.

When installing a Stage 4 clutch, it's important to have a clear understanding of the process, as it's a more involved job than a simple clutch replacement. Ensure your flywheel is in good condition or resurfaced properly, and consider replacing your pilot bearing and rear main seal while the transmission is out. This kit is designed to be a direct replacement for the factory clutch assembly, fitting your 2013-2017 Subaru BRZ, 2013-2016 Scion FR-S, or 2017 Toyota 86.
