Black ZCPs FTW, I have'nt handwashed them a single time in 2 years and they still look brand new after I pass a quick brush while pressure washing them!!
I learned my lesson about silver BBS wheels a couple years ago with my RS2s on my A4, nice when clean but PITA to wash so now I always get black unless it's an easy one to wash like the 5 spokes on my Allroad!
