How much Roll Cage do I need?

I didn't say FAA license, you have to take same FAA physical as a pilot has to take! I don't think you'll go in the 9 sec zone either! have doubts on 10;s also. to be legal for drag racing, is serious business. If the roll bar or cage is not installed or done correctly, the tech guys will reject you. next time you show back up ,they will nit pick the car. that's how it is done! something to think about.
