does anyone know the backspacing and offset for stock 15" Z28 rims?

also, i've researched a certain wheel size for my stock 86 and i think it will fit based on what I see on these boards: 15x8, 5 on 4.75, 3.25" backspacing with -30mm offset.

does anyone have a strong opinion about those fitting or not? seems like they should. they're eagle alloys 058 series and i can get a decent deal on them used.

thanks for your help.

 

The 15" 5 spoke wheels are 5 on 4.75 bolt pattern,7" wide,0mm offset with 3.25" backspacing(I'm not 100% certain on this).Check this link from the tech section to make sure your wheels will work.
