Your factory 9/10"s are +47/+30 offset- which is well sunk in.
Determine the tire's & size's you want to use & if you want to adjust your suspension from stock.
If you want stock sized tire's on stock suspension; you could easily come out between 20 & 25mm from underneath fenders..easily determined by dropping a plumb from fender & measuring how far out you want to go.
I have Forgestars & the quality
rice is very fair.
It is a mid-entry wheel, as mentioned before.
Unsure about other brands;as you can easily drop a grand or more per wheel & sometimes 2k each.
So 350-450each isn't bad; custom offsets & colors.
