Have a buddy that hates NASCAR...well to be fair if it isn't a Ducati he hates it. Used to be Honda motorcycles...he's definitely "all in" on his fandom. OK. Now the point. His big bitch is the cars aren't stock. He wants production cars with roll cages. I've tried to explain how, for oval tracks, that won't work. Struts/mounts, wheel bearings, FWD, unibody cars would have to be completely gutted and rebuilt. Much like rally cars are now. How much you suppose a rally car chassis goes for? What would be gained? Serious opinions please. I suppose they race Mustangs and Cameros in IMSA, so? How much chassis mods do they do/allow? Would you be comfortable seeing one of those pound the wall at Talledaga at 190mph?
