What type of drag racing are you planning on doing with it? Sand? Dirt? Asphalt?

what he said, different set ups but they main focus is to make your vehicle more powerful and lighter. rearrange  F=ma to get a=F/m. make F bigger (more power) and make m smaller (less mass)=more acceleration! with racing, if you are serious about wining, make sure to keep you wallet or credit card handy too.
