Exedy Stage 2 Cerametallic Disc Clutch Kit – 2004-2021 Subaru STI

Exedy Stage 2 Cerametallic Disc Clutch Kit, 2004-2021 Subaru WRX STI

The Exedy Stage 2 Cerametallic Disc Clutch Kit for the 2004-2021 Subaru WRX STI is the cerametallic single-disc solution for modified STI EJ207/EJ257 builds. The STI-specific Stage 2 kit is sized and specified for the 6-speed transmission and the EJ257’s higher torque characteristics, providing the cerametallic disc’s heat resistance and holding capacity in the correct dimensions for the STI platform.

DETAILS

• Disc: cerametallic, heat resistant, high torque capacity
• Specified for 2004-2021 STI EJ207/EJ257 6MT
• Higher clamp load than Stage 1 STI kit
• For modified STI builds with significant power increases
• Positive cerametallic engagement, adjustment recommended

The STI’s 6MT transmission and EJ257 engine make higher torque than the WRX EJ255. The Exedy Stage 2 for the STI is dimensioned and specced correctly for this application, the disc diameter, hub spline, and clamp load are all matched to the STI’s drivetrain requirements rather than being a shared-platform product.

For the modified STI, the Stage 2 cerametallic is the clutch that handles the power increases a properly built EJ257 can produce, higher boost, supporting modifications, and aggressive tune, while maintaining a single-disc package that is manageable on the street. The cerametallic engagement is more definitive than organic, but it is not the harsh, on/off character of a race disc.
