Competition-focused and engineered for uncompromising performance. The Performance Clutches Stage 3 Sport Single Mass Flywheel Kit is designed for high-output Ford Focus ST and RS builds operating in demanding motorsport environments.

The system includes our 9.2kg 4140 forged steel lightweight flywheel, reducing rotational inertia to enable rapid rev increases, aggressive throttle response, and extremely quick gear engagement. The forged construction with integral ring gear ensures maximum strength and heat resistance under extreme mechanical stress.

The cover assembly utilises a QT450 steel pressure plate, maintaining clamp load integrity during sustained high-temperature and high-load conditions.

The defining feature of Stage 3 Sport is its ceramic 6-paddle friction disc, purpose-built for competition. This rigid paddle configuration delivers immediate engagement, exceptional torque holding capability, and outstanding resistance to slip under extreme load. It is fully focused on motorsport applications — ideal for track use, drifting, and grassroots competition where rapid power transfer and durability are critical.

Why this clutch kit stands out

• Ceramic 6-Paddle Competition Disc – Aggressive engagement and maximum torque capacity for race-focused driving.
• 9.2kg Lightweight Forged Steel Flywheel – Lower inertia for faster rev response and sharper acceleration characteristics.
• QT450 Steel Pressure Plate – Exceptional thermic stability for sustained competition use.
• High Clamp Load Architecture – Designed to manage substantial torque increases without slip.
• Motorsport-Ready Durability – Built for repeated launches, clutch kicks, and sustained high-RPM operation.

Ideal for you if you:

• Run a heavily modified, turbocharged, or supercharged Focus ST or RS.
• Compete in drifting, time attack, or grassroots motorsport events.
• Prioritise torque capacity and rapid engagement over comfort.
• Demand a direct, uncompromising drivetrain connection.

The Stage 3 Sport SMF kit is a purpose-built competition solution — combining forged steel engineering, reduced rotational inertia, and aggressive ceramic paddle technology for Focus platforms operating at the limit.
