It's a very stealthy color, and since I am somewhat flexible about speed limits, stealth is a good thing. Greys are very easy to maintain too. There is a long limestone grey photo thread that I started on the Mk 7 R forum on vwvortex and you will find lots of photos there. The Golf R is a good sleeper car and very few people, even car enthusiasts, know what its capabilities are let alone how to recognize one.
The wheels are Neuspeed RSe07's in 18x8 et 45 with Dunlop ZII Star Specs in 235/40R18. I replaced (and sold) the OEM wheels almost immediately after I bought the car. I do a lot of HPDEs and autocross events, and the stock wheels and tires just weren't going to meet my needs.
