Going to replace the hub as I don't trust the stud hole long term but also going to replace all the studs. Debating if I go the ARP route or the z1 higher quality cad plated ball nose studs. I originally wanted to go with the z1 ball nose but they are too long to work with the oem wheel lock (the oem lock is shallower). So I have a set of gorilla locks coming which look to be more like the oem depth and should clear the z1 ball nose stud. Or I get the ARP and have to cut the ends off of all the nuts to make the "open" style on the lathe since no one sells an "open" style to fit the oem rays. So more work to go the ARP route (removing rear hub and cutting lug nuts) but once done it's done but curious if anyone has used the z1 ball nose and what the results were long term, tracking, no seized nuts, broken studs etc.
