5mm spacers under the rotors and Brembo M4's work without further adjustment. The RS rotors are narrowband so most calipers will have clearance issues with the floater buttons. On my HPK's I had to grind a bit off the pads.

I had them made locally, cost 40€. Not sure if the five bolt versions are available, all I've seen are the six bolt ones for Tamburini bikes.

Race spec Brembos are for narrowband rotors, yes. But as mentioned the M4's work as well and require no mods (apart from brake lines, 1098 ones are a direct fit). And they are a whole lot cheaper than any proper race caliper.
