I'd get the Corally F1 it already has foam tires. It's way better than most of the kits out there because it's more like a real pan car. As for the motor good luck I'd get a 13.5 and a 1 cell kinetic and it would be fast and handle. but if your planing to go racing some where I'd check with the group to see what they are running. With the motor your planing make sure your have plenty of parts available.
