Lubrication
1. Use graphite only. 
 
2. Break in the wheels by spinning them with lots of graphite. 
 
3. Other than the good polishing of the axles, dump the axles and wheels in a ziplock bag with some graphite and shake them for a few days prior to the race. That way the wheel and the axles are as slick as can be.

4. No lubrication is allowed inside the church building - please step outside the entry doors to lubricate your cars!
