Turbo II Wheels Question - 20" vs 21"
Need some help as to whether this will work. I like the look of the 21" Turbo wheels for the Cayenne but this size wheel limits one's choices for all season tires. However Porsche has a 20" version of this wheel for the Panamera. My question is whether these will work on the Cayenne.
Specifically, the 21" wheel has an offset of ET50 is 10J in width with a 35 series tire. The 20" version (front) has an offset of ET65 is 9.5J in width with a 45 series tire.
Therefore focusing strictly on the offset, the 20" has 15mm difference in offset which is a little over .5" (.59"). Also I believe that means the wheel will sit about .5" further into the wheel well.
My question is will this work from a technical perspective? I'm not quite sure if the .5" difference will be noticeable and if it is could a 10mm spacer be used? Also if I do not use spacer's would that difference require suspension adjustments (i.e. toe in, toe out, etc.)
Would appreciate any and all feedback.

Another option is replica if you are set on 20's. I got "Replika" brand Turbo II's, 20x9.0 offset of 48, and they fit perfectly, and are perfectly flush with the side of the fender on my 2013 Cayenne without flares or spacers. You can also save several thousands.
