E46: 8 x 18 Front ET 47
9 x 18 Rear ET 26
E9X 8.5 x 18 Front ET 29
9.5 x 18 Rear ET 23

Now if I did this correctly, the correction is about 23F/9R. So would a 20F/10R spacer give my 18's the same kind of look as if the E9X 18s were on?

Thank you
You would need a 24mm spacer in the front and a 12mm spacer in the rear in order to have the outside edge of the wheel sitting at the same point. However the same tires on the narrower wheels will be sitting more upright than if they were stretched onto the 1/2" wider wheels. The place that the edge of the tire tread will sit is difficult to predict but you do know that it will be centered on the wheel.
Thanks. I didn't know there were spacers bigger than 20mm. Sounds too big though.
