If you are going to just drag race then brakes, frame, and suspension are even more important. I have seen people go off the end of a track. Make things scarier we have a track up here that used to have a forest of trees after the track. If you are not sure about what you need I suggest you hire a shop with race experience for the frame and suspension part of it. No doubt you will have to convert to a 4 link set up to keep it straight on the track.
