Joe,

How long do they last when they are not driven like Top Fuel and Funny Car
dragsters where major clutch slip is part of the launch technique?

In other words, if the car is driven as a "normal" sports car with a mix of
city and highway driving but not trying to avoid bog on sticky tires at an
autocross/pro solo as a major part of its life, is the clutch a weak point?

Thanks,
