Redco,
Here is a setup for you to try. I didn't have much time to fine tune it, but hopefully it will give you a something to try that will work for you well. I didn't have access to treaded tires, so I had to use Sorex36R with no traction compound added. The car had good steering and was controllable if you wanted to stay on the throttle some in the turns. Let me know how the car does in practice and If you need to make some changes I will help you dial it in.
