The Front windshield can have a hole no larger than 60mm and the rear bumper cannot be cut higher than 55mm when the chassis is sitting on 20mm blocks. The hole in the front windshield cannot be more than 60mm (and no more than 50% above the top of the windshield. according to the last race I attended, but the 2009 ROAR rule book does not state this) You may have an additional 30mm hole above the fuel tank filler kneck for refueling as long as it does not instersect with any other hole in the body. Side windows may be cut out and a .375" antenna oppening is allowed. Tunning holes for the engine and a hole for glow igniter are also allowed. Wheel openings are allowed to be no more than 10mm larger than tire diameter.
