EVO Clutch Kit - Stage 4 RSR-STEEL Lightweight RACE
Suitable for the following applications:
993/TT, 996 GT3, 997 GT3/RS, 996TT/GT2/X50, 997.1TT/GT2
Our Stage 4 RSR-ST (STEEL) Lightweight RACE clutch package was developed and engineered for our "in house" 850 HP 997TT. We utilize an OEM SRE “999” MotorSports pressure plate and increase the clamping force of the by about 500 Lbs. This clutch kit utilizes the technology from our Stage 3 clutch with the addition of an OEM "EURO RS" lightweight flywheel. This high clamp force pressure plate combined with our custom designed sprung hub ceramic disk will hold high horsepower applications without slipping. This system was specifically designed for use with the EURO RS lightweight flywheel for a more aggressive clutch setup. This system is suitable for daily street driving and capable of handling the road course as well as the drag strip.
This clutch conversion will transmit slightly more transmission noise into the cabin of the car. At idle speeds, there is a rattle sound that can be heard which is transmission noise that is typically absorbed by the OEM dual mass flywheel. If you are concerned with this increased clutch / transmission noise, this may not be the correct clutch conversion for your application. Please contact us directly so we can help determine the best setup for your application.

The wide range of Performance Clutches, developed, designed and tested by EVOMS are more expensive than most clutch systems on the market. Quality components that have been carefully analyzed and tested are not cheap. Rest assured that in the long run, our clutch systems will out- perform and out last cheaper, inferior clutch kits that are available. The amount of money saved by purchasing a clutch kit that has to be removed due to poor performance or failure will cost more time money and headaches in the long run. Our properly designed clutch systems have the following essential advantages:
• Utilizes extremely high strength and properly matched friction materials - helps deliver more transmittable torque
• Incorporates higher pressure plate clamping forces - helps deliver increased HP/TQ without slippage
• Maintains excellent clutch engagement characteristics.
• Designed specifically for different power levels, driving styles and applications
• Features heat treated friction surfaces for superior thermal resistance
• Direct replacement for the OEM clutch system
• Increased clutch life
The latest CAE equipment, such as Pro-Engineer (3D Design) and FEM (Finite-Element-Method) calculations are used to custom design and configurations as close as possible to each individual application. We also design and build Diaphragm Springs and all key components of clutches to realize ultimate performance.
To evaluate the reliability of our products properly, careful analysis and tests are conducted in each vehicle and on test benches which have been developed by EVOMS.
Our Performance Clutches are assembled by hand. This guarantees the highest quality and accuracy in clamping load and release characteristics.
