Alright so can someone school me on backspace vs offset? Our offset is 38mm right? Does that mean the mounting plate is 38mm forward (closer to the fender side than the caliper side) from the center of the wheel. Where as backspace is measured from the mounting surface to the back edge of the rim?
Where on a 15x6 for example 38mm offset is roughly 4.5in backspacing seeing as 38mm=1.5mm???
Sorry if im confused just trying to figure this out.
Edit: I just found this @

Offset= [backspace-(rim width)] /2
Soo, on the 15x7 with a 4.0 bs
[4-7]/2=1.5 or 38mm.
Would that fit my car?
