Important: Gearbox input shaft compatibility depends on the 32.5x35-26N spline profile. Also verify that the 240 mm clutch disc is compatible with the flywheel and pressure plate being used.
Installation
Important: This disc has a rigid construction without torsional damping. Depending on the transmission configuration, additional mechanical noise and drivetrain vibrations may occur, particularly at idle.
Important: Intended for motorsport applications. The engagement characteristics of a rigid ceramic clutch disc may differ from those of a conventional clutch, with more abrupt engagement and reduced everyday driving comfort.
