ZF Sachs Racing™ Clutch System (RCS)
The engineers at ZF Sachs Race Engineering have been technical partners of several Formula One teams for years now. Their expertise is now directly available in the ZF Sachs Racing™ Clutch System, which can be individually configured for all racing series.
Standard clutches are only of limited suitability for racing. Comfort is one of the main focuses of development work on standard clutches. As a result, these clutches tend to be relatively large and heavy.
Completely different requirements are placed on clutches used for racing. Here the focus is on reducing the weight and moment of inertia (MoI), in order to enable maximum engine acceleration as well as minimum shift duration. Both the weight and the MoI can be significantly reduced by decreasing the clutch diameter and by using special materials.
RCS clutches have not been developed for specific vehicles, but can be used in virtually all cars. However, adjustments, have to be made, such as to the geometry of the flywheel, position of the releaser and the limitation of the clutch release path.
More detailed technical information on our ZF Sachs Racing™ Clutch Systems – product line can be easily accessed and downloaded by consulting our current Catalog.
With its modular RCS system, ZF Sachs Race Engineering offers a high degree of variability for racing clutches. The system can be configured to provide individual solutions for specific vehicles and tracks. Our clutches are developed for virtually all racing applications. Their low weight and moment of inertia are among the most important parameters for racing. ZF Sachs Race Engineering guarantees rapid availability and unproblematic exchange of individual components.
It is possible to customize the clutch to changed demands simply by exchanging individual components. Even wear parts can be easily and quickly renewed.
The RCS range comprises 4 different clutch diameters: 115 mm, 140 mm, 184 mm, and 200 mm. Friction linings come in carbon, sintered, sinter pad, and organic materials. Another option is the number of friction discs. ZF Sachs RCS offers 1, 2, 3, or 4-disc clutches. The clutch clamping force should also be considered. Moreover, individual components can be produced in different materials. The following pages contain more detailed explanations of individual clutch parameters.
The benefits of the ZF Sachs Racing™ Clutch System are as follows:
- Friction-Ø: 115, 140, 184 and 200 mm
- Set-up as 1-,2-,3- and 4-disc clutch
- rigid plate and plates with torsion springs
- multitude of different hub spline
- Low inertia of masses through the use of high-tensile aluminum
- Very high engine torques
- Easy replacement of individual components
- High durability
- Special solutions for specialized and extreme applications possible
- Expansion into a Carbon variant is currently underway
You can put together an individual clutch based on your application needs and requirements. For further information download the RCS catalogue.

backRegal Autosport victorious in the VW Racing Cup
27 year old Tony Gilham was crowned the 2007 VW Racing Champion. He claimed the victory in the penultimate round, despite racing with a failed turbo, after his nearest rival retired due to mechanical problems. Tony finished the season with 462 points, 38 points ahead of Steve Wood who took 2nd place.
The Regal Autosport team had a fantastic season and prepared a stunning car, "We scored in every race and thats what wins championships. We had bad luck along the way, like starting three races from the pit lane, but the golf has been consistently quick and reliable".
The Regal Autosport Mk5 Golf GTi proved to be one of the most reliable cars in the series and Tony was the only driver to secure points from every race. We supplied Regal Autosport with a Performance clutch from ZF Sachs. The Performance Clutch range has proven itself on many occasions and the team have been very impressed with the quality and reliability of the system.
