I got a brand new 2011 ultramax C4 senior champ kart. Having trouble finding places to run with decent classes. The idea of cutting the cage off and running as a flat kart came up. I called ultramax and they said that my wheel base is 42, where a flat kart is 40, and they wouldnt recommend doing it, that it would warp the frame.....then he tried to sell me a new frame, so it was hard to take his advice. Has everyone ever done this, or heard of doing it?
