Show Me Your Battery Kill Switch
Burntorange 70 is absolutely correct. Locate the battery as far to the rear as possible to increase the weight transfer effect, and on the passenger side of the trunk to counteract chassis twist due to motor torque.
GoFish - Check the NHRA rulebook for rear firewall requirements. I don't think it's anything to tough to live up to. Probably .040 aluminum may be sufficient (sorry, I don't have a current rulebook here at work).
