Choose your specification

• RTSTF-3135 Twin Friction – rated to 455 lb-ft. Dual-surface drive plate with aramid facing on the flywheel side and a segmented face on the pressure plate side for strong initial bite, smooth engagement and low wear.
• RTSPC-3135 5 Paddle – rated to 510 lb-ft. Ceramic-style puck layout for rapid engagement and high torque capacity, popular for fast road and circuit use.
• HD option – uprated clamp load with everyday manners, great for spirited road use where longevity and refinement matter.

Why enthusiasts pick RTS for their BMW manual gearbox

• Significant increase in clamping force to transmit more torque than a standard clutch setup.
• Aramid friction material and segmented pressure face help control temperatures and limit fade during repeated hard use.
• Pedal effort remains close to stock for comfortable commuting and traffic.
• A smart alternative to stage 2 and stage 3 clutch kits, with real-world drivability.
• Complete performance clutch kit engineered to outperform the original equipment system.

Technology that works on the road and on track

The Twin Friction design uses advanced aramid material that resists wear compared to conventional facings, while the segmented pressure plate surface and ER2 features improve cooling and stability as temperatures rise. The spheroidal casting micro-structure of the cover helps deliver consistent clamp under load. The result is a clutch that runs cooler for longer, holds serious torque and still feels civilised in daily use.
