Thanks for all the responses. I did the search for the 25.5. I seen all I needed to see. I'm not going to do that to my car. I guess if I want to go faster I will have to build a 2nd car. I was hoping the NHRA would lower the roll cage requirement since many street cars today are runing faster than 9.99. It's safer to run these cars at the track than it is to run them on the street.
Back in the day you needed a roll bar at 11.99 then they changed it to 11.49 et. It's safer to run a car at 140 mph with a 5 point harness and roll bar than these guys running 120+ with a factory lap belt and no bar.
