The ATS Carbon Twin Plate clutch has been designed to handle high power tuning applications from 650hp to 800hp with high durability and smooth operation. Standard (Spec I) delivers powerful transmission performance up to 650 hp (at the wheel) while the Spec II with 1,900kg clamping force has a capacity of 800 hp (at the wheel).
These superior characteristics were achieved using our thoroughly studies and tested friction material and our original non-mesh random-weaving method, which dramatically eases the operating feel, making it far less rough in traffic congestion or on a slope for a heavy-duty clutch. Start up is also extremely soft and smooth. In addition to durability that is over 3 times higher than metal, a remarkably significant reduction in impact on engine and transmission components has been verified.
Features
- With the introduction of Spec II, ATS successfully made the pedal effort lighter than stock (w/ 1,400kg clamping force) which has enhanced your driving comfort and pleasure immensely.Â
- Because the 1100kg Clutch Cover can receive the power of 1200PS and the 1350kg can receive of 1500PS.Â
- The Spec 2 - Clutch pedal is lighter than normal OEM clutch but the life will be shorter about 50% less than the Spec 1 Clutch.Â
- The higher lever ratio = less force required however stiffer preload and shorter clamping stroke = Â less tolerable clutch disk wear before it will loose clamping force and slip, So the life of the Spec II clutch is shorter than the Spec 1
