I was considering buying a set of wheels for my sons district race. Is it a huge difference between buying a machined wheel vs prepping a set ourselves. I have all the tools necessary to prep a wheel but I don't have a lathe or cNC to be as precise as others. I notices they are using a lathe to keep the nail head set better which I would think offers a decent advantage. Any thoughts? By the way his race ruleS are all wheels have to touch. I will write a new post about that as well. Also how do you guys feel about buying wheels for a BS race? Fair or unfair? I noticed a few ppl had bought wheels aND axles in is pack race so to keep competitive it's a must. Even if I do purchase wheels I will still prep a set with him so that he can understand the process. I think it's very important to keep my son involved in all the steps of building a car. Last year a guy would not even let his son touch the car to hand it to the judges. They won't learn a thing like that. Anyway let me know what you guys think. Thanks
