This will probably sound like a very dumb question to most of you, but... I would like to paint my brake callipers (silver or black, opinions please!). How do the callipers actually come off!!! Is it an easy job to do? and what should i be especially careful of? I have a black S3, which colour would suit? Looking for an understated (but still visible!) look. Does anyone have any pics of their cars when it's been done?
