searched and searched need info on BS and offset..

But I could not find the little graphic that displays/explains backspacing and offset....I know that offset is the distance from centerline to the hub face (positive goes towards curb side of wheel)...but wouldn't backspacing just be negative offset?!?!

ALSO anyone have the stock numbers for the 15" 16" and 4WD wheels?!?!?

Just to shed more light on my earlier post,.... The 8.5" rim width is measured @ the wheel weight area. i.e. Width OD. The industry measures rim width where the rubber mounts. i.e. Width ID. That in mind these 2000 ZQ8 rims are 8.0" widths (ID).
