2008 GCR 9.1.3.7a.1 states "Cars classified in ITR may utilize any wheel diameter up to 17” or retain their stock diameter wheels if larger." does this apply to my 1994 bmw325i ITR car even though in the schedule in shows wheel size as being 15/16? I also found where any pulley size and combination is approved...is this true?
