The racing clutch in drag cars costs so much because it is one of the most important parts on the entire car! Without it, it doesn’t matter how much power you car has or how good of a reaction time you might have, you won’t be going anywhere! The clutch helps transfer that power from the engine to the transmission and then on to the diffs via the driveshaft. The more power a car has, obviously, the heartier the clutch must be! This video gives us a great idea of how a modern racing clutch is made.
