The EJ-series Subaru engines share common clutch bell housing and transmission interfaces across multiple generations and models. The Exedy Stage 4 twin disc kit addresses the maximum-output end of EJ-series performance, whether it is a highly built GD WRX, a modified STI, or a tuned Forester XT, the twin disc system provides the torque capacity needed when single disc options have been exhausted.

Twin disc clutch engagement requires adaptation from single disc driving habits. The system engages across both disc surfaces simultaneously, producing a firmer, more decisive engagement than any single disc. The transition period varies by driver, but most adapt within a few hundred miles of normal driving.

Why Choose Exedy

Exedy is the world’s largest clutch manufacturer and the OEM supplier to more than six major vehicle manufacturers globally, including Toyota, Honda, Subaru, and Mitsubishi. Every Exedy performance clutch is designed and manufactured as a purpose-built performance component, not a modified OEM part, not a remanufactured unit, but an engineered system built specifically for performance use from the ground up. Exedy’s research and development happens on actual race programs alongside their road car product development, meaning the technology that wins championships filters directly into the street performance catalog. When you install an Exedy clutch, you are installing a product from the company that builds the OEM clutch for the car it is replacing.
