For short circuit and short runs short wheel base is best for long straight away and hitting jumps at a high rate of speed such as the baja 1000 long base wheel is best.
A lot of room is needed to carry extra spare tire bigger fuel thank and other equipment when running baja 1000.
i see what you mean there....i've allways wanted to build one of those and run a race like that!...i just want to get my truck on some of that gorman i've seen in your vids...have you ever ran a race like that leo?
