So, is this a Royal Ambassador / Royal Ranger car or was the "ra race" portion a typo? I saw in your earlier post that you'd purchased a plug-and-play body from DD4H?
+1 on what O.D.D. said.
Make sure the wheels are mounted close to the body — 1/32" (or a credit card's thickness). Don't be sparing with the graphite. Add some to the hub, spin the wheel. Repeat. A lot of times. One more puff of graphite into each hub right before turning the car in.
If it is an RA/RR car, I'm not sure about any other special considerations for it.
