I love the Sport Design Wheels on my Club Coupe--they take a bit longer to clean, but it's not that bad. It may take me 5 minutes longer than the Turbo look wheels on my Boxster S.

I use a Microfiber Wash Mit when washing mine. Just wrap your fingers (inside the wash mit) around each spoke, go up and down each spoke one at a time, and you're done in no time.
