I'm converting the front brake set up on my e90 330 to the 335 setup which use huge single piston alloy calipers.

The set I acquired were a horrible green so I had a mate sand blast them and now they look like new.

Question is shall I paint them or not? I was initially thinking black or silver, then the dark blue similar to the current bmws that have the brembo setup.

What's people's opinions on a silver car with silver wheels?
