The tires are without a doubt going to be your first area of attention. Grey in the back with Pink in the front is going to make for a car that has massive amounts of steering. I would recommend going with one of the combinations I suggested before for carpet.
Get some 64 pitch gears on that car without a doubt! Your gearing seems pretty close so pick up a 100t spur along with 28,29 & 30 tooth pinions to start with.
Most Hitec servos while inexpensive and good to start with don't belong in 12th scale cars. Hitec servos are cheap and the quality reflects that. In 12th scale you are moving a very small car at a very high rate of speed and you need an accurate and slop free servo that centers up well. I have watched many newcomers sabotaged by a poor quality servo, it's just not worth it in the end. Larry's recommendations are spot on!
