Looks great man. I agree NASA/SCCA should be fine with what you've done. By choosing to minimize the door work you only lost a couple inches of elbow space and potential crush zone. That said, nothing's going to crush your cage! You'll be fine in and out...I am 6' 1" and able to get in and out with the door closed. The bars are actually very easy to slide in on and sit on as you exit normally. I removed my windows and scoops last season to make sure I wouldn't have an issue getting out in a hurry. Just added a window net to keep my arms inside should I get into a rollover situation. I forget, did you do a center roof bar? I got the idea from that extended wheelbase Coupe last year, and I think the West Coast team might be adding one now.
