Isn't a Slipping Clutch a Bad Thing?

No! In stick shift drag racing, a slipping clutch is actually quicker, more consistent, and easier on parts. Dedicated drag racing clutches, known as "Adjustable" or "Slipper" clutches, are designed to slip. This allows for more consistent launches, quicker E.T.'s, and fewer broken parts.
