Well, I can't remember the e.t. threshold for the stud-thru-the-open-lug rule, but my 11 second Monte got busted at Atco for having blind front lug nuts. Had to install the extra long studs on the old rotors. They are still the M12 size, with open style lug nuts on weld draglites. I think I ordered the studs from Lingenfelter?? If you need me to look this up, let me know and I can dig in the receipts. It was one of those deals where he let me run that night but said "next time I'm not going to let it go".
