Composite Wheels

Composite wheels consist of various parts. The primary components are rims and wheel discs. These components are fastened to each other with special screws and a special procedure. This ensures the wheel's function, proper seal, safety and true running. These important requirements cannot be guaranteed under shop conditions and using shop tools. WARNING Composite wheels must not be disassembled or repaired!
