A basic bracket car should be a fairly easy build as long as you know exactly how fast you want to go and don't change the goal. Cars built from the ground up for a specific purpose usually go together fairly well. It is the guys who start off with 10 second cars that then want to run 9's that have the problem since a bunch of stuff needs to get cut out and redone. If you are going to run 9's then list out all of the stuff required by the rule book and put it all in the car from day one. The build that Forest is doing would be a good one to follow if you're planning on running 9's.
