I was looking in my manual at all the examples and most of them had 6ish backspace with 30mm offset.

I found a good deal on some boss 338's and was wondering if these would work? I have a fox width rear and not running fenders...

Here are the specs

Staggered Setup:
2- 17 x 8 Front wheels
Offset: +2mm, Backspace: 4 1/2"
AEWC part# 3387-8812-2AA

2- 18 x 9.5" Rear wheels
Offset: -4mm, Backspace: 5"
AEWC part# 3387-9912
