Spacer size need to be considered in the context of the installed wheel offset. For example, a 20mm spacer with the OEM wheel (be the 18" or 19") will stick out, as the ET is 22 to begin with. A 15mm spacer with the front OEM wheels (ET 29) is pushing it.
So any discussion of spacers need to include also the ET of the wheel in question or the particular spacer size chosen could be the wrong one.
