Not true. I ran the texas mile in March and whhile there a z06 flipped over while going 232 mph. He crossed the finish line at 202 upside down...someone was praying for him because his roof because he only had a 4pt roll bar.
Great event, but some people only consider high HP but nothing in terms of safety. There was a Ford GT (Mullet) and he would run 223 all day and night without a cage...only a helmet. WTF????
