Yeah but currently the Ronals that I have are a positive 35mm offset. Getting a wheel with a 20mm offset and getting rid of the 1/2 inch (12.7mm) spacer moves the wheel in. That means that I should be able to rid myself of the spacer, eat the 2.3mm and have the wheel/tire in the same place on the car right?
Please make sure I am right by going here...

Then you put in the specs for my current wheel which is 17 X 7.5 with 35 mm offset. You would have to imagine the spacer in there that makes the mounting position more towards the car. Then if you change the offset to 20mm and get rid of the imaginary spacer...same place right?
