RTS Performance SMF Clutch Kit with Single Mass Flywheel 1.8 Turbo VW MK4 Golf GTI / Audi A3/S3 (8L), TT (8N) / Seat Leon (MK1)- HD, Twin Friction or 5 Paddle

Uprated solid flywheel clutch package for VAG 1.8T 6 speed applications

Transform the way your 1.8 turbo VAG car puts power down with this proven solid flywheel conversion and performance clutch assembly. Designed as a dependable replacement for factory dual mass hardware, it delivers stronger torque holding, cooler running and long term reliability without sacrificing everyday drivability.

We have fitted this kit on customer builds at MJ Modifications and the feedback has been consistently excellent. Engagement is predictable, pedal feel remains sensible and the drivetrain copes far better with heat during spirited use and track days.

Why choose this conversion

• One piece flywheel for superior heat control and durability compared with dual mass units
• Weight closely matched to the original to keep pedal feel and cabin noise civilised and to maintain crankshaft behaviour
• Improved NVH management via the clutch damper that helps protect the gearbox from chatter and driveline shock
• Up to approximately 60 percent higher torque capacity than a standard clutch, ideal for mapped 1.8T builds
• Cost effective long term ownership thanks to simple serviceability versus DMF systems

Choose your friction setup

Pick the specification that suits how you drive your 1.8T, from daily road car to fast road and occasional circuit work.

• HD - A robust, street friendly option with a higher clamping force for tuned cars that still see commuting and motorway mileage.
• Twin Friction - Hybrid drive plate with an aramid based lining and segmented pressure face for cooler operation, reduced fade and around 50 percent less wear than conventional linings. Perfect for fast road and track use while keeping engagement smooth.
• 5 Paddle - Ceramic paddle disc on both sides for maximum bite and heat resistance. Best suited to higher powered setups and non daily use where ultimate holding power is the priority.

Key technical benefits

• Efficient heat dissipation helps the clutch run cooler for longer sessions
• Solid flywheel design minimises vibration through increased inertia compared with many lightweight options
• Clutch damper function suppresses gear rattle and reduces vibration transmitted to the transmission
• Optimised mass moment of inertia to minimise the risk of crank walk while retaining OEM like manners
