What do your chicken strips look like?
If you have the standard 150 section up front you will NOT use the last inch of rubber on either side. The rear is a different story - with stock suspension setup you can run right to the edge of the 240's. I think this is a far better gauge for lean angle ... If you roll off the edge of the rear you've leaned too far (which is supposed to 35°).
LHS peg rail will scrape before you run out rubber and the RHS exhaust heat sheild will touch down after the the peg has worn.
I'd put the stock boingers back on the rear (4 bolts and 5mins work) and see what happens...good luck
