Roll bar or not!!!???

Put it together without a bar, make a pass down the track and if goes faster than 11.49 and you want to race the car put a mechanical throttle stop on it. They are like 15.00 from Jegs and Summit. I have few buddies who run them so they don't put a bar in their car. Just do frame connectors, torque boxes and weld the seams on the K-frame.
