Exedy Stage 1 Organic Disc Clutch Kit – 2004-2021 Subaru STI

Exedy Stage 1 Organic Disc Clutch Kit, 2004-2021 Subaru WRX STI

The Exedy Stage 1 Organic Disc Clutch Kit for the 2004-2021 Subaru WRX STI is a factory-quality OEM replacement clutch for the EJ207 and EJ257 6-speed platform. Exedy is Subaru’s OEM clutch supplier, and this Stage 1 kit reflects that engineering relationship, the same quality standards that go into the factory STI clutch, applied to a replacement unit.

DETAILS

• Disc: organic, smooth OEM-equivalent engagement
• Designed for stock and near-stock STI EJ207/EJ257
• OEM-equivalent clamp load for the 6MT
• Full street drivability, installs and drives like new OEM
• Broad 2004-2021 fitment coverage

The STI’s EJ207 and EJ257 engines run higher factory boost than the WRX, which means the OEM clutch is already specified to handle more torque. The Exedy Stage 1 for the STI reflects this, the organic disc is developed for the STI’s higher torque inputs while maintaining the smooth progressive engagement that makes the STI manageable in daily driving and traffic.

For the stock or near-stock STI, this is the correct clutch replacement. Stage 1 is the appropriate specification for a factory power level STI, moving to Stage 2 or higher when the engine is still stock adds engagement harshness without any benefit. Stage 1 holds the stock power level reliably and maintains the driving experience.
