ATS Non Conversion Pull Carbon Twin Clutch Subaru WRX STI 02-07

ATS Non Conversion Pull Carbon Twin Clutch Subaru WRX STI 02+

The first in the industry, the evolutionary ATS Conversion Free Carbon single / twin clutch does not require a pull – push conversion. It is conversion free.

Structure

• In the diagram below, the upper part in light purple color is the stock clutch cover. The structure and materials of the rest are basically the same as those of a standard ATS carbon clutch.
• The adaptation to either single or twin clutch is made by changing the height of the pressure plate.
• The stock cover is installed on the casing wall. In order to secure enough strength, the casing has been integrated onto the flywheel.

Rated Horsepower

• The rated horsepower depends upon the clamping rate of the clutch cover.
• With a new clutch cover of 1,100kg clamping rate, a twin clutch and single clutch could handle up to 700hp and 350hp respectively.
• Please adjust the estimated capacity accordingly if you re-use a stock cover with a weaken spring rate.
• ATS recommends a clutch cover with a higher than 1,100kg clamping rate for the CF single carbon.

Attention

• For spirited street driving, please use a new clutch cover with a high clamping rate (preferably more than 1,100kg)
• If the clutch starts slipping, adjust your driving style and minimize the damage to the steel plates. Then, change the cover to a new and preferably one with a higher clamp rate.
• You may consider upgrading from single to a twin.
• For racing use, ATS recommends using our standard carbon or metal clutches with an ATS clutch cover.
