Used to be on my mustang, one of the bolt patterns is 5x114.3 not sure on the second pattern they are 8 inches wide. Chrome is in rough shape, I was going to strip them down and paint them but just bought some deep dish cobras instead.
Definetly above +30, not sure exactly though I cant find anything about them online. Ill probably just measure them if I remember to stop over at storage and do so.
