The bolts are almost countersunk just stick out a bit. I like that as i had issue with shearing the bolts on the Sim headlock methods before.
They are 17x9 with 4.5”BS and 12 degree offset, they sit and fit really well.
In fact, they kinda cured the steering “darty” feelings i had with the stock wheels- just drove to big bear and back with some heavy wheeling and zero issues on the highway at 80...very happy
