The ultra-lightweight and heat-resistant characteristics of the CC composite offer drivers exceptional strength, response, and durability. Carbonetic clutches deliver a very smooth operation that is also very easy on a vehicle’s transmission.

Carbonetic Clutch Offerings

Carbonetic offers single, twin, and triple plate carbon clutches, along with carbon limited-slip differentials (LSDs). Carbonetic’s single-clutch model is designed for use in regular and light-tuned vehicles. They act similarly to an OEM clutch, with only a slightly heavier pedal feel. Drivers will experience excellent performance at half clutch for easier street driving. The CC composite provides dramatic weight reduction and improved synchronization during shifting. The twin plate clutch is ideal for Time Attack cars, drag racing, and heavy-duty track cars. Like the single-clutch, it behaves really well on the road with minimal vibration, if any. It seems a bit heavier than the single plate kit with a slightly more aggressive feel. The triple-plate clutch is designed for high-output-powered vehicles, capable of holding 1100 bhp. It is designed to be incredibly strong and built to repeatedly handle the severest of driving conditions, as this clutch is ideally suited to high-powered race, road, drift, and drag applications.

Carbonetic’s dynamic carbon clutch series is designed for high-powered vehicles ranging from 600 bhp to 1500 bhp. This includes the twin and triple-plate clutches, which deliver powerful performance that is unmatched by the competition. The key benefits include a reduced impact on the engine and transmission components due to our C/C-MC technology. A large reduction in inertia weight also enables quick shifting while minimizing drivetrain losses. The Carbonetic clutch is also the most controllable and cost-effective multi-plate clutch available on the market today.
