Our local Pack rules state "You must use official BSA Pinewood Derby bodies, wheels and axles. We do not allow pre-cut bodies re-sold by third parties. We also prohibit BSA Grand Prix Pinewood Derby wheels and axles that have been altered and re-sold by third parties."
So as an inspector, I would accept any wheel that started life with BSA on it. If the Revell axles are easier to polish and work better, I may start stocking up on them for workshops. Most of the build teams simply use the nails in the box.
