Typically, racing clutches allow for a quicker or smoother shift. All racers generally need more holding power with less heat. There are many types and styles of clutches. And though all clutches have the same purpose, they do not all perform the same. Some are made for your everyday driver, while others are made for racing or off-roading. When certain performance criteria is not met, your overall vehicles performance will diminish greatly. While your family car is probably seeing more miles and has the OEM (original equipment manufacturer) specified factory or aftermarket clutch, the racer will have a much higher performing clutch.
