Keep the black ones, no point spending money upgrading to the Trophy calipers if you don't really need their performance.
As soon as you hit the track the calipers will be full of brake dust, unless you are one of those who takes the time to dismount the wheels, dismount the calipers and clean the calipers just for fun.
