SACHS PERFORMANCE 883082002058 Carbon Racing Clutch RCS 140

Description SACHS PERFORMANCE 883082002058 Carbon Racing Clutch RCS 140

For virtually all categories of motorsport, ZF Race Engineering offers a broad portfolio of racing clutches. SACHS carbon clutches (RCC) are used from touring cars and rally cars up to Formula 1. The entire ZF Motorsport range benefits from top-tier technology proven in series such as Formula 1, Super GT, and WRC.

Development focuses on minimal diameter, the lowest weight and moment of inertia, outstanding temperature resistance, and consistently maximum performance. The RCC 4/140 carbon racing clutch meets the tough demands of modern motorsport, combining robustness and reliability with uncompromising competitiveness through excellent mass and inertia characteristics.

The system mass of just 2.44 kg and low moment of inertia enable noticeably faster rev-matching, shorter shift windows, and sharper response. These are tangible advantages in sprints, on tight circuits, and in classes with limited installation space.

Lowest mass

One of the major strengths of a carbon racing clutch is its low mass and resulting low moment of inertia. Designed for the lowest possible mass, it transfers engine Torque to the gearbox as quickly and directly as possible. Lightening measures in the cranktrain that reduce the moment of inertia noticeably increase vehicle acceleration in the lower gears.

Faster acceleration

If the clutch has a moment of inertia of 0.061 kg·m², for example, with a gearbox ratio of 13.4:1 in first gear, this acts at the drive wheel with 180 times the value (13.4²). Converting the moment of inertia into vehicle mass results in an additional weight of approximately 145 kg in first gear that must be accelerated. Thanks to the extremely low inertia of the SACHS carbon clutch, shift times are significantly reduced and the vehicle accelerates faster.

Maximum service life

Pressure plate and shim packs are available for carbon clutches to compensate for carbon wear. These compensation pressure plates allow the clutch to be reset to as-new condition, significantly extending service life.

Each unit undergoes stringent quality checks and is individually tested and measured before shipment. Preload force, installation height, release characteristics, and the preinstalled carbon stack thickness are documented. The included document supports maintenance and the shimming process using compensation pressure plates for refurbishment.
