You may think it a good idea to swap out your stock clutch with an aftermarket heavy-duty race item to handle all of your car's extra power. If you use that car for anything other than racing, you won't have a good time, according to the folks at .
While a normal clutch features a springs and low-friction material used to absorb slipping and hard launches, a race clutch features ultra-grabby material that limit's the driver's ability to slip without overheating the disc. Overheat it enough and your clutch and flywheel will actually fuse together, locking you out from controlling what gear you're in. In addition to hard launches and stress-filled hill starts, you'll also have to worry about stranding yourself on the road.
