Although the designs of cars differ, you really can not go wrong with any high performance TC out there. There are "trends" with some, where the people have to have this one car because it JUST came out, then there are others with which stick with just one company. I would just check out what your local parts suplier has the most parts of, and check what people are running at the local track. Right now, it seemes like the shaft drive cars have taken over, yet belt drive cars are still as competitive.
