With the modular based Racing Clutch System RCS, ZF Race Engineering offers a high variability in racing clutches. Hence it is possible to configure an individual customization to the vehicle and track. As the RCS clutches are not developed vehicle-specific, they can be used in nearly all racing cars. Only changes such as geometry of the flywheel, position of the releaser and the clutch release travel or end stop may need to be modified.
