pdmustgt when you turn the shoes around it changes the leverage the shoes have on the springs because of direction of rotation. The no slip factor also has more of an effect on enguagement feel. I dont think people realize how much clutch shoes slip during normal trailing use. I never tell people to take my word for it just spend the time to try & you'll se what I mean. It makes a 5,000-7,000 rpm difference coming out of corners.Your eng will bog badly if you change nothing else.
