This gives it a sling shot effect when the track levels out. Also set the axils so the wheels wobble slightly to prevent toe in and help with wheel alignment. Slightly bore the hubs so only the top wheel hub touches the axil. Sand the wheels as smooth as possible. Remember ground clearance,weight, balance, drag, and aligment is the key to win.
