Wheel Backspace question....

[Racie]

I have a chance to get some custom 3 piece forged wheels already built I think we need 5.5 backspace on the rear. If I want to run these wheels would I have to run a spacer or do a mini tub?

Here are the measurements:

19 x 8.0 Fronts: 5” X 5” (127 X 127mm) Bolt Lug Pattern

4-½ “ (114.30mm) Backspace

0 Offset 4”/4”

20 x 10.0 Rears: 5” X 5” (127 X 127mm) Bolt Lug Pattern

4-½ “ (114.30mm) Backspace

1“ Negative Offset 4“In/6“Outside
