Glad the finish is good, even if the color is wrong, or not what you were expecting!
So I tried and failed miserably. The backspace on the 9" wheel is 6.4375" and the 10" wheel is 7.3125". From there, I tried my best to calculate the offset and I came up with 39.7 and 49.2 which is obviously WRONG.

I did get on the calculator on rimsntires.com and messed with the offsets until their backspace matched mine and by that method, the rear offset is 45 or 46 and the front offset is 35 or 36.

So basically I have no idea what my offsets are :

I have to say that this project is definitely making me feel very annoyed with Forgestar.
