I have a broken wheel stud, right rear wheel. I am going to replace it and, since I don't know what caused it, will probably end up replacing all of the studs over time. I have two questions. First, what are the specs for the stock studs? I've come up with 12x1.5 mm threads, but cannot find the length. Second, is there a better replacement than stock? I have stock wheels and lug nuts and no plans to change that any time soon, but if there's an upgraded part available from ARP or elsewhere, I'd just as soon go that route. I have been searching and am having the damndest time coming up with anything helpful. Thanks in advance.
