The STR Clutch line-up was designed to hold high capacity power while still retaining a relatively light clutch pedal. This technology was driven from our racer's demand for a lighter clutch during long endurance races in Japan. Heavy clutch pedals lead to driver fatigue during long endurance racing.

OS Giken Clutches:
Through research and development of high performance engines, OS Giken realized the need for the production of higher quality, more durable clutch systems to meet the rigorous demands of race and sport driving. The OS clutch is able to transmit engine revolutions and output to the drive train without loss. They are made of the highest quality materials and their durability is second to none. OS Gikens continual research and development has brought about many improvements and are confident that the OS clutches can meet the demands of even the most heavily modified vehicles.
What is the difference between an OS Giken clutch and another companies clutch?
Through years of development and since its first introduction to the public in 1983, OS Giken clutches have always focused on extraordinary durability, drivability, and effective power transmission. In order to properly develop a clutch system to maximize drivetrain performance, OS Giken determined that it would be most effective to engineer and manufacture clutch kits as a clutch/flywheel package. By doing so, a clutch kit can be installed which has already been properly matched to your MINI. Additionally, the design, engineering and manufacturing of OS Giken clutch kits promote improved durability (through friction plate material which is carefully selected and alloyed so that the plates match with the materials of the flywheel and center plate), maintained drivability (through revised leverage mechanisms to provide higher disk pressure while reducing pedal effort), increased longevity (through a superior design and usage of extra manufacturing processes for strengthening).
