What Wheel/Backspace For 2" Narrow Rear End
 

Looking to get advice on backspacing for a Narrowed (2" per side) S60 setup on a 1999 Trans Am? I have done a ton of searching on the forum but it seems the norm is 3" of narrowing and the rear I purchased has 2"

More than likely going with some sort of Weld Wheel. Really like the look/fitment of this car. (15x10 w/295's and a 4.5 bs)

Based on the math, does that mean I can achieve the same thing with a 5.5 BS?
