I have decided to go altered and have a spoiler/wing question. Rule book says "maximum spoiler chord measured on the top surface is 10 inches from the trailing edge of the body." Does the rear bumper of my Mustang qualify as leading edge of body? My Sons Mustang drag car has a wing on the back and it extends about 9.5 inches beyond the bumper. Maybe 16 inches from the edge of the hatch.
Thanks in advance!
