Daily Driver Roll Cage, comfort?

my dads demon runs 10.60s at 126-128mph. the car is driven to and from the track and he drives in alot in the summer time. he is making approx 525hp. that car will embarrass pretty much any production car built. he runs 12.5 x 28" et streets and the car hooks on the street. the car is scary fast. you can get going so fast in such a short distance that it really is dangerous. 700hp will sooner or later get you in trouble one way or another. that and at that level of power it takes alot to time and money to maintain it. 500hp is plenty enough power to make you the fastest guy on your block.
