RTS Performance Uprated Clutch & Single Mass Flywheel Kit (SMF) for VAG 5-Speed 1.8T 20V & 1.9 TDI – VW Golf MK3/MK4, Audi A3 8L & TT 8N, Seat Leon MK1, Skoda Octavia MK1 – HD/Twin Friction/5 Paddle – DMF Delete Solid Flywheel Conversion – Stage 2/Track

Uprated Single-Mass Clutch and Flywheel Package for VAG 1.8T and 1.9 TDI 5-Speed

Unlock dependable power delivery and crisp engagement with the RTS Performance Single-Mass conversion. This clutch and solid flywheel package is a proven upgrade for VW, Audi, Seat and Skoda 5-speed models built around the 1.8 turbo petrol and 1.9 diesel engines. Ideal for fast road, spirited driving and trackdays, yet refined enough for daily use when specified correctly.

This setup replaces the factory dual-mass unit with a robust single-piece flywheel and performance clutch assembly, giving stronger torque holding, consistent bite and excellent heat control under repeated hard use. The flywheel mass is engineered to closely match OE inertia to keep pedal effort and cabin refinement in check while maintaining crankshaft loading characteristics.

Why this RTS solid flywheel upgrade makes sense

• Direct replacement for tired or noisy dual-mass units on 1.8T and 1.9 TDI platforms.
• Matched overall weight to factory specification for familiar pedal feel and minimal change in noise and vibration characteristics.
• Simplified single-piece design with excellent thermal stability for long service life and cost-effective future clutch refreshes.
• Improved driveline protection thanks to RTS damper technology which helps manage NVH and reduces shock through the gearbox.
• Confident torque handling for remapped and tuned applications while staying road-friendly.

Choose the specification to suit your build

Twin Friction

RTS Twin Friction uses a specialist facing on the flywheel side and a segmented pressure plate surface to move heat away quickly and resist fade. The aramid-based material shows substantially lower wear than conventional linings, and with RTS ER2 and spheroidal casting know-how it dissipates heat efficiently. Designed to transmit up to 60 percent more torque than a standard clutch, it is the sweet spot for daily-driven cars that see fast-road and occasional circuit use with excellent drivability.

5 Paddle

The 5 Paddle option uses ceramic pads on both sides for serious grip when power and torque are significantly increased. A unique damper hub helps tame vibration and free-play chatter, making it a strong choice for higher-output builds and occasional track work. Expect a firmer, more motorsport-oriented engagement.

HD

The Heavy Duty variant focuses on durability and higher clamp load for spirited road driving. It is a tough, dependable upgrade when you want extra holding capacity without going to a paddle design.
