I should have explained the pics - I am going with 18 for ride comfort / pothole protection - living in NE OH, the roads are not the smoothest. My option is to keep as is or have the 18 painted black upon delivery.The 2 pictures aren't quite fair, since one is an 18 inch cayman wheel in silver vs the 20 inch Carrera S in black.
I prefer the silver look for the same reasons as GregW said. However I also prefer the 20 inch aesthetic. But 18 inch may have some unsprung weight and ride comfort/pothole protection benefits. 20 inch has the option of fitting MPS4S however. 18 inch currently doesn't.
That is an excellent point - I never took into consideration the inside open space of a 20 inch rim - with an 18 you have less space - and I have only looked at the black on 20 inch rims - I appreciate the insightI would definitely keep the 18's silver and think that painting them black would be overwhelming.
The 20 inch wheels appear to have a lot less visual mass; this combined with the narrower tyre side walls means the black effect isn't as overpowering. Just my opinion of course.
Would like your input - Struggling to decide between Black or Standard wheels on Graphite Blue Boxster
I'm tellin' ya: Once you go black, you'll never go back: >For my 718 B-GTS, I went with a middle-ground between the silver and black ... the 20" Carrera Classic Wheels. My car is Night Blue Metallic so the all black wheels were just too dark but the silver to too bright for the black trim on the GTS.
