Do you want the BREMBO logos?
If not ... I did the calipers on my project car with some high-temp rattle-can paint 15 years ago, except where it's been chipped by careless wheel fitters it's held-up pretty well.
Worth a go IMHO.
Yep. Add some brake caliper high gloss clear and some Brembo stickers off eBay, and they look as good as factory. If you prepare the surface correctly.
