Back in the Saab 93/95/96/97 days, they used lugbolts as well. Instead of a post, there is a large cast ring into the face of the hub (or drum) that you hang the wheel on, which the ring on the wheel lines up with. Fronts spin fine, because the tranny keeps the axle from turning while you line it up, and the back doesn't move at all because the handbrake is on when you change tires. Actually works better than the post as far as I'm concerned. As to why not use studs at all, well, I assume it has to do with making a critical part with a more reliable and fixable design. Replacing a broken stud involves special tools _and_ the part, and a stud & nut, compared to a tapped hole, is more failure modes which could cause big problems. Dave Hinz
