Go with 20's; they seem to be the sweet spot for the Macan. I'd also stick with Porsche wheels; known quality, guaranteed fit, and usually the best looking as well. Just my 2 cents.
How much do you want to spend?I HAVE A ABASE WITH 18" WHEELS. AM CONSIDERING 19" WHEELS. YOUR POINT OF VIEW PLEASE
I agree. Another thing to keep in mind is road condition where you live. If residing anywhere in the NE, would not recommend 21.Go with 20's; they seem to be the sweet spot for the Macan.

Do you have base suspension with the 21s?I went from 18", to 19", to 20" and finally to 21". Also moved from a base to an S. I'm down in Florida, so the roads are pretty smooth. I haven't noticed any harshness between all the sizes and am happy with the 21's now. I think they fit the Macan very well. YMMV. I second the "use Porsche wheels comment"
That looks really good and lower than my base setup, or just a great angle. I stayed away from 21s after reading about extra harsh rides but I guess it depends where you drive. I'm in South Florida with very smooth roads. Will swap up to 21" when my tires wear out.I do, the standard steel springs.
