Carbonetic Triple Carbon Clutch 1100kg Subaru WRX STI 04-06

The Carbonetic Triple Clutch is designed for extreme power as high as 1500 PS. Its half clutch operation is the ultimate in control, surpassing that of a single or twin clutch. The inertia weight is kept to a minimum, thus enabling quick shifting. By instilling our clutch with triple plates constructed of the non-mesh random waving method, the Carbonetic Triple Clutch is astonishingly strong and built to repeatedly handle the severest driving conditions.
