Yeah but silver is too safe - dull, nearly all cars have silver alloys.
I'm not going to recommend some bright green/orange/whatever - naff imo, save those for a full-on track car.
Most cars on the road don't have big enough alloys that you'd want to draw attention to them.
But a 182 on 16's - perfect!
I'd say gloss black or a dark grey. Black probably would be too much of a contrast to the rest of the car, so how about some shade of grey, something darker than the silver of the bodywork. I think most people (car nerds or not) would see it as being quite classy. I'd actually prefer a proper shade of dark grey on mine rather than the standard anthracite - I reckon it would look better with the black gold.
I wouldn't worry about the lowered thing - they have a great stance to begin with, mines not lowered.
Just my thoughts.
