You bet. Will seal them well with dodo juice wax before fitting. They will be easier to keep clean than the stock calipers as they are painted.
Is this a Thing among detailers?
Asking because waxing wheels with normal wax for paint doesn’t work; the wax gets hot & the brake-dust gets in, and cleaning is a total PITA ‘cos you basically need to strip the brake-dust impregnated wax to clean it.
Is this a special type of wax which works on calipers?
The silver front Brembos on a Series 1 clean nicely with just a wipe (I use a crappy old chamois ... new chamois for windows, middle-aged chamois for wiping inside doors & the like, then when it gets really old & crappy it gets used for wheels & under the sills & brakes).
