and I'll second that.... On a unique car such as your Coupe, would certainly be a good plan to get in touch with your track or divisional tech folks... Always best to build the bars and/or cage to be in compliance with what the tech people want to see rather then have to cut things out and redo them later!!!! Never hurts to be on the good side or at least have a working relationship with the tech folks at the track you'll be running at!
