The SPEC Stage 2 clutch kit for 1999–2004 Mustang Cobra/Mach models is a single-plate upgrade focused on stronger holding capacity for modified street and occasional track use. It replaces the factory clutch with higher clamping components suited to increased torque while retaining reasonable drivability for many street-driven builds using a 26-spline transmission input.
