Q: how much can you modify the jack, gas can, air-wrench, track bar adjusting tool, spacers, etc. before it's considered cheating? Will they allow teams to use modified tools in the pit area?
A: i know that the air impacts they use are totally custom.... it was on speed a couple weeks back and they have the choice of steel, titanium, or carbon fiber cases, where the exhuast port is located, how many vanes are on the motor and such..... it was an interesting clip on nascar garage if im not mistaking
