I have an old dwarf car that I got a little while back for some work I did for a guy. I know nothing about the car. I've been in racing before but have never raced a dwarf or modlite. It needs a body built anyway. My question is, how much difference is there between dwarf cars and modlite, chassis-wise? One reason for wondering is, around my area, dwarf cars are running 600s and modlites are running 1000s. My car has a GSXR 1000 in it. I like speed and power so I'd love to stick with the 1k motor if I can. Any insight and info is appreciated! Will most likely be running dirt if that matters
