OS Giken TR Series Clutch & Flywheel Kit (04-21 STI)
The TR Clutch series line-up was designed for vehicles which have substantial increases in engine power. The billet aluminum cover provides a more direct clutch pedal feel, but still maintains ease of engagement due to the unique leverage mechanism of the diaphragm spring to reduce overall pedal effort.
The TR2CD was designed with high power Turbocharged engines in mind. This type of clutch caters toward the heavily modified engines. The dampened hub clutch discs are 215mm in size and are good up to about 800lbs ft of torque reliably. The aluminum cover allows for higher clamping force (increased capacity) and will handle the hard abuse often found at the track.
We utilize full face metallic clutch plates to achieve high torque capacity from our clutches. This allows for us to use much softer diaphragm springs to achieve equal or better torque capacity compared to our competitors with substantially less pedal effort.
