I think I'm just gunna cut rears down since I have to do it for 2whl too. If I'm doing that many sets, its can't hurt to do another. I can't wait to see what tire wear is going to be like 3 days of practice and 3 days of racing. Oh boy I better get some glue remover if I want to be able to move my fingers by the mains! I also just found out another thing, If the track is swept its a holeshot track... Oh joy....
