Per the ARCOR rulebook:Q-ball said:Accroding to ARCOR and ROAR, how much of the rear of a stock car body can you cut out? Is there any limit?
Note that this DOES allow cutting out the rear of the car body, within limits...3-12: Bodies cannot be trimmed higher than the lower body trim line. Unless otherwise stated in Appendix-A, the rear section of a body may be cut out as long as the rear sides and quarter panels, including the tail lights and side portion of the rear bumper remain intact. It is recommended that some portion of the cut line remain visible to help speed technical inspection. If the body has no lower body trim line, then the fold line is considered the cut line.
