grind up pencil graphite and use it on the axles as lubricant; it will reduce the coefficient of friction between the axle and wheel.
shave off mass from the wheel- reduce the amount of rotational force to get the wheel rolling.
if its low profile- use some property of fluids that will give it lift/down force.
use your weight placement and/or axle placement about the cars center of mass to optimize the equilibrium balance on the wheels.
a high gloss finish might also reduce the drag force.
