Default What backspacing for billet specialities?

Gonna be ordering a set here from a local guy i know. Hes looking for specs and such. I know they make um f-body specific..but is that just the rears? So the proper wheel for the rear would be

15x10 7.5 backspace.

What are the proper specs for the front runners? 15x4 by what?

Most guys, myself included, are running 15x4s with 1.625 backspacing

can you run no spacers with those back spaces? I researched a bit and came up with a 2.25 front backspace. So i wouldnt need spacers.

I had already clearanced my front calipers for Draglites so my Billet Specialties fronts fit with no spacer. If you get the FBody specific rears then they fit with no grinding or spacers.

Then again 1BADTALS1 took just a little off and his fronts fit
