Its a Matter of tastes... Now a days all car are good enough to win.
If your beginning, look for something that has the lest breakage... That way you can go all out and slam that thing around, to find your limits. This way you'll always be running at the Ragged Edge, and can find a fast groove, and rhythm for your driving style(this is ONLY when your the Only one on the Track)... But also learn to drive smooth, this is the most important thing you can do, because in traffic the fastest guys are always the smoothest. This is for Any kind of Racing... It was the most important lesson I learned when I used to Race Bikes and Cars...
Keep the Rubber(or Foam)on the Road!!!
