I was discussing the options over the weekend.. I am definatley going to take 3/4" from the lip width for a total of 15 3/4" to frame .But as far as stretching the radius I either will cut it like you did, or slit the front edge to the lowest body line and move it foward 1", don't know if that will be enough though..whats your take on going 18's" ? I still like 15" steelies painted body color's... thats the debate I have going on. more pro street than pro touring.. I have no desire to run run Watkins Glen, but I do to run Norwalk raceway.
