what colour is your car mate if its red silver or any light colour id say black would look ok me i like the alloy my self
Find yourself a second chrome trim, then do it! That way if you don't like you can swap it back - I've done the same thing for my rear diffuser - or, although i'm not sure of this, you could go to a print / design shop and have it wrapped in some black memory film to see what it's like, then if you don't like it just pull the film off.....
Would it be possible to vinly wrap it whilst it's on the car.
