Longer wheel studs?

The car came with Kelsey hayes front disc brakes. It now has those same rotors and SSBC replacement bolt on calipers.
I'm beginning to think that these wheels are the problem. Can any one here running a factory wheel spin off one of your lugnuts and maybe try to measure how much stud is sticking out? I'm gonna do the same with these wheels so we got something to compare
Again thanks for your input....Pete

I have thought that for a while but just hadn't figured out where, but I think I have it now.
I can do that on the rear and it is a 10" sbp just like you have.
