This is my oldest son's last year, so we're going for it! We won the pack race last year and we had a fast car, but there were still a few things we did to be "safe." We went from a 5" to 4-3/4" wheel base. Moved COG back to 7/16" from 5/8". We have 11.59g sitting on the DFW. 3" steer over 4'. As long as we didn't mess up the alignment and don't pop a wheelie we should have our fastest car yet. Race is Sunday.
