I am the most bang for a buck guy you will meet. I have no experience with the NPC, but numerous examples of a certain other well advertised local clutch which just does not suit the applications it applies to. Trust me, spend once, spend less. You want to argue with 450+ rwkw on a mainline with slicks and semi slicks on the track, numerous 9000rpm launches, come see me, got the experience. When it comes to this, I don't even think of the clutch, simply, it works. Or you could spend half the money, at least twice, and worry about the clutch. Simple really. And yes, I am taller Steve you joker you
