The reason is that it's less expensive to manufacture wheel bolts than studs and nuts. I put threaded studs on my 82TQC and I modified Porsche alloy wheel nuts to match the Audi Shape. ---------- From: Graydon D.

Gary, 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 automatically. 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? Later, Graydon D.
