Looks nice.
Nice heavy bracing on the lugs. The only thing you have to check is if the caliper can match the thickness of the disc. So that the pistons don't pop out when the pads are virtually worn.
But being calipers from a production car and not some bbk with extreme thickness discs I cant imagine that that'll be a problem.
If I were you (I know, I'm not) I'd beadblast the calipers, get it sprayed nicely (If you can spare the money, powdercoat), and maybe rebuild the seals with a rebuild kit.
And some nice brembo or bmw decals on it (I'd go for brembo, I love the italian styling in their logo). There's no sin in showing off your hard work
