This has got to be one of the best things I learnt to do a few years ago that made my cars so much faster and more consistent. I even do this when I am racing SlotIt, NSR, Scalextric, ScaleAuto and other models cars. You need a special tool, but there are quite a few available. Good quality grinding of axles and setting the tool up correctly is very important to getting the best results.
