Aside from that one little thing that is not explained in the manual......your car should work great if you build it 100% per the instructions. Tire size and choice and how you sauce your tires are perhaps the most important things to "tune" the car to your personal driving preference. While maybe not the absolute fastest, black fronts with grey or greylo rears are usually a good solid and easy to drive tire selection. Those work best on my home track since we tend to get some fuzz pickup and that family of tires is less prone to grabbing fuzz off the track. But if you want every last ounce of performance, you may want to try some blu or double blu fronts in combo with either blu or greene rears. Happy motoring.
