Not going to get into specifics. Inquire to the rules commity and maybe they will post a notification about it. Your steering wheel can not be more than 10 inches from the front roll hoop. Doesnt specify in the rules but we got called on it when I submitted rules confirmation on the front hoop and bulkhead supports. This is 10" longitudal distance, tangental from the edge of the front roll hoop and the steering wheel. Will probably only affect a few cars out there but this is being mandated by the rules commity. The word "proximity" actually means "within 10 inches" for rule 3.3.1 B. I cant tell you how aggravated I am but at least they (Michael Royce in particular) have been responsive and nice and have given us a reasonable option to to meet the rules. This is defintely going to make part of my car ungainly and misplaced which also drives me up the wall because of how particular I am.
