[brain_dead00]

hey guys, imin the planning stages of my bastool racer, for my auto project at school, i was drawng it up on autocad and started looking at my dimensions.. i have a 36" (3ft) axle with random 8" rubber (no air) wheels for fronts and 13" air filled tires for the rears and the frame i have designed is 24" wide by 53" long.. the wheels will be 36" apart and i am going to mount the fronts 36" in front of back to try and keep it short, and square.. my only question is, how/wide is a typcal racer / frame? with wheels mine should be 36" by 53" is this wider / longer than normal? any help / suggestions would be appreciated, what lengths is everyone running?

typical frame using classic cruiser or rules set by nobra max tire width outside to outside is 40 inches and max wheelbase is 29 inches stool height is no shorter than 30 inches. but those are just rules I think woodchuck customs has the offical rule book for download .
