Here is another one Racers

Its your choice most of the time, but your ET will determine alot. My experience is sportsman cars run exhaust, lap belt, no cage or roll bar. I would use nhra or ihra rule book for ET safety requirements first. Then determine where you fit in at each track. I run 11.70's at 113mph. I have 5 point belts, 8 point chrome moly cage, steel firewall between trunk and cabin, batt cut off, long wheel studs, jacket, pants, fire exting, ect. I run pro at most events, some places call it hod rod.
