now the question is, where do I get longer studs for the front rotors. I have a spacer/adapter for the rear, that should put me right where I want. I find out in a week or so. But the fron will need more backspacing the the rear, hence just using the spacers with the holes, maybe 1/2 inch or so. El coolmino, in the Air Force the rule is there should be stud exposed that is equal to the diameter of the stud. So you have to have threads sticking out past the nut, equal to the diameter of the bolt/stud. Just curious here what people have used. The lugs I will be using are the acorn style, but I I don't get a longer stud with a 1/2 to 9/16 spacer, I don't think I 'll have that many threads sticking through to catch. Thanx for all the replys.
