The RTS Performance SMF Clutch Kit with Single Mass Flywheel is a top choice for VW, Audi, Seat and Skoda owners wanting a reliable, hard-hitting clutch upgrade for fast road and track, while still being usable day to day. This RTS SMF conversion kit replaces the troublesome DMF with a durable single mass flywheel and performance clutch, delivering sharper engagement, stronger torque capacity and excellent heat management.
At Nforcd we have fitted these kits to customer cars and feedback has been consistently positive for drivability, pedal feel and reliability. If you want a VW Golf MK4 clutch upgrade, Audi A3 8L clutch and flywheel kit, Audi TT 8N clutch kit or Seat Leon MK1 clutch upgrade, this RTS SMF kit is a fantastic solution.
Why choose the RTS Single Mass Flywheel conversion
- Ideal replacement for failing or noisy DMF units on 1.8 T and 1.9 TDI platforms.
- Weighted the same as the OE DMF to keep pedal feel and cabin noise changes to a minimum, and to keep MOI on the crank the same as OE to minimise the risk of crank walk.
- Technically, the SMF will reduce engine vibrations due to the increased inertia of the solid flywheel.
- Excellent heat dissipation and no complex high-wear DMF internals for greater longevity and cost-effective future replacement.
- Increased protection to your transmission as the RTS clutches absorb more NVH and deliver a longer life compared with a DMF setup.
Choose your clutch option
Available as HD, Twin Friction or 5 Paddle to suit your power level and driving style.
Twin Friction
RTS unique Twin Friction drive plate uses a special flywheel-side friction material and a segmented pressure plate face. The aramid friction exhibits up to 50 percent less wear than conventional materials and reduces fade as temperatures rise. Combined with the spheroidal casting micro-structure and ER2 technology, the clutch dissipates heat more effectively and runs cooler for longer. Designed to transmit 60 percent more torque than a standard clutch kit, it is suitable for everyday driving, fast road and track use while maintaining a user-friendly driving experience.
5 Paddle
The 5 Paddle option uses ceramic pad material on both sides for maximum power handling. RTS uses a unique clutch damper function to absorb NVH, helping to suppress free-spinning gear movement and vibration transmitted to the transmission. Paddle clutches are best suited to higher power builds and occasional track use. Expect a firmer, more performance-focused pedal feel.
HD
Heavy duty clutch option for drivers wanting a robust performance clutch upgrade alongside the RTS SMF conversion. Ideal for spirited fast-road use where durability matters.
