Not in quadracer their not ebc is good for around 45 hp so tusk would be less Kevlar barnett is good for 65+ might be more cant reall remember their was thread on this. I have a used ebc clutch thats in great shape I would sell you for cheap. Biggest thing is springs. If you have a 87 to 92 250. You want to use 85 86 250 springs they hold more pressure then 87 to 92 spring . More pressure means less slip.
