I have always liked the Audi double spoked wheels Bristle. I passed this comment a little while ago to someone else here about a set of wheels that were an RS4 wheel called a Titan. They were finished in grey. The ones I really really like though are the R8 five spoke wheels. Similar to one another to look at, but with less spokes.These remind me of my all time favourite, the BMW 313 rim. Very open wheel, letting you see a lot of calliper and rotor. Very pretty. Might do some homework and see if these are doable on the S4, ( the R8 wheel ).
