RTS Performance SMF Clutch Kit with Single Mass Flywheel 1.8 T / 1.9 TDI VW Golf (MK3/4),Audi A3 (8L), TT (8N) / Seat Leon (MK1)- HD, Twin Friction or 5 Paddle

Uprated clutch and solid flywheel conversion for VAG 5-speed 1.8 turbo and 1.9 TDI

Looking for a clutch upgrade that handles real-world torque, hard launches and repeated heat cycles without giving up? This RTS heavy duty clutch and solid flywheel package is the proven VAG solution for tuned 1.8T petrol and 1.9 TDI diesel builds. It replaces the failure-prone dual mass unit with a robust solid flywheel and performance clutch assembly designed for fast road and track use while remaining driveable on the street.

We have fitted these kits on customer cars and our own projects at MJ Modifications. Engagement is consistent, bite is strong and feedback from owners has been excellent for daily-driven remapped cars through to weekend track toys.

Why choose this solid flywheel conversion

• Stronger holding power - engineered to transmit up to 60 percent more torque than a factory clutch
• Improved heat management - efficient dissipation keeps performance stable under repeated hard use
• Durable construction - fewer high-wear moving parts than a dual mass assembly for longer service life
• Refined drivability - flywheel mass is aligned with OE to help keep pedal feel and cabin noise changes to a minimum
• Gearbox protection - integrated damper helps absorb NVH and reduce drivetrain shock
• Ideal for remapped, hybrid turbo and fast road setups, plus occasional track days

Choose your friction option

Twin Friction disc - Dual-surface technology with an aramid lining and segmented pressure face offers excellent bite with smooth engagement. The aramid material exhibits up to 50 percent less wear than conventional linings and reduces fade as temperatures rise. Perfect for daily drivers, spirited road use and circuit work where you want strong torque capacity with user-friendly manners.

5 Paddle ceramic - Aggressive puck design for higher power builds. Ceramic pads on both sides deliver firm engagement and increased heat resistance, ideal for non-daily cars and track-focused setups. Expect a firmer pedal and a more direct feel.
