Ford Focus RS, ST - Clutch SMF Kit Stage 2 Sport - PC-7004-S2SF

A true hybrid performance system designed for dual-purpose use. The Performance Clutches Stage 2 Sport Single Mass Flywheel Kit is engineered for drivers demanding significant torque capacity gains while retaining controlled engagement suitable for daily driving.

The 9.2kg 4140 forged steel flywheel lowers rotational inertia, allowing faster rev climb, improved throttle modulation, and quicker shift transitions. Its integral ring gear design ensures outstanding structural strength and resistance to heat distortion.

The cover assembly features a QT450 steel pressure plate, delivering exceptional thermic stability and consistent clamp load under repeated high-temperature cycles.

What defines Stage 2 Sport as a hybrid solution is its segmented ceramic friction material mounted to a marcel spring assembly. The ceramic segments provide high torque capacity and superior heat tolerance, while the marcel spring introduces progressive cushioning between friction surfaces. This combination delivers strong bite without the abrupt engagement of a full competition disc — making it suitable for both fast road and circuit use.

Why this clutch kit stands out

• 60–120% Higher Clamping Load – Substantial torque capacity increase over typical aftermarket systems.
• Segmented Ceramic with Marcel Spring – Hybrid design balancing performance bite with street drivability.
• 9.2kg Forged Steel Flywheel – Reduced inertia for sharper rev response and faster gear changes.
• QT450 Steel Pressure Plate – Superior thermal resilience under aggressive driving.
• Street & Track Ready – Built to endure repeated heat cycles and high-load conditions.

Ideal for you if you:
