My 70 Firebird evolved over 15 years from a street car. Once I started taking the car to drag strips, road tracks, mile events, etc. the tech inspectors kept saying you should install harnesses, roll bar, fire system, and other things. One time at Road Atlanta the NASA tech guys came to my pit area between sessions to have a lil chat explaining that barreling down the back straight near 140 MPH with only a helmet, cotton clothes, and 4 point Schroth ASM harnesses in a 40 year old car with no fire suit, air bags or other modern safety equipment was pushing my luck.
And so it began, full cage for attempting 200 MPH LSR's. Kirkey full containment NASCAR seats. I couldn't believe I was I cutting up thousand dollar seats to make them fit the car and shortened the sides of the halos to see for the street. Two fire systems, one for fuel tank and engine suppression and one for passengers. Six point Schroths for harnesses. I struggled with the race vs street thing for a long time while continuing to attend events. Now I'm currently rebuilding the car after a complete frame off, bare metal restoration/rebuild. I decided on a race car with license plates. Better to put up with inconvenience street driving and be alive after an incident. I have other cars I can use for street if the Firebird is to unrefined.
This time, no HVAC or sound deadening but retain carpeting, headliner, a faux rear seat and basic stereo. Rear firewall sealed, front firewall mostly sealed other than steering shaft and electrical.
