Which will get to the end of 1/4 the quickest

Does your car have a roll cage?
Not now it had a mild steel 6 point but when I slowed the car down by taking out the R block stroker i took out the bar. I never thought it would run this good so I didnt think I'd need it. The mild steel 6 point was over 100lbs so go with chrome moly if you dont have one yet.
Does your car have a charging system? or does it run on battery only?
