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 TS2A was designed with Naturally Aspirated and Supercharged engines in mind. This type of clutch will give the best engine response possible. The clutch discs are 184mm in size and is good up to about 350lbs ft. The stamp steel cover allows for ease of engagement/disengagement and will handle the hard abuse found at the track.
