Hmm, not sure personally. Think they would have been better in an anthracite colour as I agree with the above, black wheels are nice if they are contrasted with a diamond cut like the pic above. All black wheels merge in with the tyres and make it look like aftermarket, although at least you have the red callipers to break it up a bit.
As you say, probably best seeing them in the flesh so to speak rather than in pictures.
If you don't mind me asking, what was the price of the refurb? £75 a wheel? I take it you lost the audi sport logo?
