I have the same wheels on my 718 Boxster S and had them on my previous 981. This time around I had the ceramic coating applied to the wheels. Now less brake dust sticks to them and it's much easier to clean them. It was definitely worth the $500 to have it done.5 months of ownership here. Great car! Biggest PITA is keeping the wheels clean! lol
It's called CQuartz. I went in to get the wheels and calipers done, but ended up having them do the entire car.Agreed with ceramic coating, well worth it (gtech?).
