Performance Clutches Ford Focus RS, ST - Clutch SMF Kit Stage 1 Street HD

The Stage 1 Street HD Clutch and Single‑Mass Flywheel Kit is engineered for Ford Focus RS and Focus ST models requiring improved torque capacity and sharper driveline response while maintaining daily‑drivable characteristics. The heavy‑duty pressure plate increases clamping force for reliable power delivery, while the high‑friction organic disc provides smooth engagement suitable for street, fast‑road, and light track use.

The included single‑mass flywheel reduces rotational mass compared to the factory dual‑mass unit, improving throttle response, acceleration, and shift precision. The assembly is designed for direct fitment, retaining factory hydraulic actuation and compatible release systems. This kit is ideal for vehicles with mild to moderate performance upgrades.
