Most of my cars have independent front ends, to make those I use a hollow axle with a ferrule in one end to act as a retainer. The wheel on that end does not have a set screw, the other side uses a set screw, so the axle does rotate. I use either Zero Grip rubber tires or hard low grip urethane tires, the rubber tires are coated with nail polish. If the front tires have little grip using independently rotating front wheels may have little effect in eliminating tire scrub. Since I don't have a 1/32nd track I have never done any testing to see if there would be any difference in lap times.
