I wondered the same thing and asked, the body shell and all the sheet metal is original. Even after the fire. The subframe is original but highly modified. Everything else is new. Like the brakes, holy cow they are big hence the large diameter wheels. But if your speeding along at 266 mph I would want to stop. Has a rack for steering. Control bars are different. I remember they were really concerned about tires. Above 200 mph it’s a whole new world. They had a lot of rear end gear ratios. I was told there is a special set up for top speed. Road race, silverstate etc. and takes a long time to change the car. I am going to make a model of the road race or silverstate car. The fastest camaro.
