I was looking around and sbox engineering has a set of racing wheel studs. The description is 0.509" knurl and 3.25" length. I tried to find a Fiesta stud drawing from Doorman but couldn't find one. Looking at the thread pitch, knurl diameter and length, it seems like sbox is selling Moroso late model Corvette/Camaro wheel studs. Even buying Moroso brand from Jegs is expensive but looking up the late model Corvette/Camaro application, I have found ARP 100-7708 (I think) for less than half the cost. That's a 2.75" stud which I hope is long enough, I dislike having too much extra length. I'm hoping to confirm our knurl diameter and stud length, then I'll try a set. I don't know if these fit, but they might and if anyone is looking for an upgrade, this is probably a good place to start.
