long wheel studs for factory discs
I don’t have my rule book here with me, but unless the rules have changed most guys don’t need those worthless long PITA studs.
The rule book used to say that “one times the diameter of the stud must go into the hex portion of the lug nut” and that’s all it said. My have changed, but I doubt it because that’s how most fasteners work.
That means if you are using a 1/2 inch stud, only a 1/2 inch of the stud needs to be into the hex portion of the lug nut. That’s it. The track tech dude will argue, so have your rule book handy. Because making the stud any longer has ZERO affect on strength of the fastener or bolt.
If said tech dude snivels, either run open ended lugs or pull off one lug to show him, while reading the rule out of the rule book to him.
He won’t be your buddy any more, but most likely he never was. And he should know the rule book.
