Need some info before we can answer. What type of racing; oval, onroad, offroad? How big is track? What surface, carpet, dirt, other? How long are the races?

I would go as low as you can go. 10 or 11 by 60. I just put a 6900 in mine and it is way too fast for the indoor offroad course nearby me. I'm currently at 13x55 and have my radio throttled back to 60% or so right now. I'll be changing the ratio asap.
Either that or just make sure you cut some flaps into the body to promote airflow.
