I have never heard that before. In fact, every race car that I
have ever seen that was not allowed to use a single knock-off style wheel
nut, has had studs not bolts. Granted that is also done primarily for
convenience, but I don't think they have a tendency to loosen
I have replaced bolts with studs on a couple RX7s with never any
loosening problems. Mind you, I check them alot, because I change them
alot at autocrosses. Most every other car in the whole world uses studs,
so I don't know why VW/Audi and Mazda can't figure it out.
Maybe someone else has some further input?
