im not sure what rotors you would run with those. stock is 360mmx36. the 390 mod uses 390mmx36mm these are for a 402mmx39mm... maybe only the stock CCBs? but then you would need the CCB calipers as well, which already come with the 402brackets anyway.

The only real drawback is, installation. The bracket wouldn't require sliding the spacer between the caliper/bracket while feeding the bolt thru -- which is a minor inconvenience but the only real downside and that if someone were to get the brakes serviced at a shop, some brake tech may not realise the spacer is involved.
