Description

Clutch Masters 850 Series Street twin-disc clutch kit with push-type conversion for the 2004-2021 Subaru WRX STI (2.5L EJ257, 6-speed). The 8.50-inch Strapped Street setup pairs a ceramic disc with a fiber-tuff disc for smoother engagement than the Race version, and the included push-type conversion replaces the factory pull-type STI release geometry. Note: this is a performance part for modified vehicles; professional installation recommended. Break in per manufacturer instructions.
