I do build a lot of car ... When I'm in the mood I really enjoy building cars.. There are a lot of variable in making a fast car , even a competitive car against the top guys... Wheels play a big role, the drill/alignment, then his fenders are installed , gaps , weightplacement , and last PREP.. Tuning is crucial also. This series here I have built a few new cars that I'm going to mess with each race and tweak on to see what kind of speed can be found.. I will have a few new cars for Nationals but won't be seen till Nationals cause of a few new ideas I've been siting on.. Save the best for Nationals ..
