I am having spacers made for my car that I want to be hub and wheel centric however the spacer is only 3/8 thick so I am not sure if the hub doesn't stick out more then that or around that because if that is the case, obviously I can only make the spacer hub centric, anyone happen to know how much the hub sticks out? I don't have access to a jack so can't take the wheel off to measure it.
