The TS Clutch Series line-up is the original technology used since the birth of OS Giken. This style of clutch has stood the test of time for good reason. It is capable of handling light to medium engine tuning. Most tuners will find this clutch suitable for their power figures. The stamped steel cover maintains a moderate pedal effort for the given capacity it can hold, while the heat-treated alloy clutch discs improve durability and maximize performance.
The TS2BS was designed with Supercharged/Turbocharged engines in mind. This type of clutch will give great engine response possible while also handle a fair amount of torque output as well as ease of pedal by utilizing a softer diaphragm spring. The result is a very soft clutch pedal for applications that fall well below the maximum torque capacity of a standard TS2B.. The clutch discs are 204mm in size and are good up to 500lbs ft. The stamp steel cover allows for ease of engagement/disengagement and will handle the hard abuse found at the track.
