need help/info quick

[SRH]

will a 450r caliper and caliper plate bolt up on a 250r or will a 450r caliper bolt up to a 250r caliper plate? any info would be helpful

Front or rear? I've been told that the rear's are interchangeable but I'm not sure about the front.

im pretty sure they will work, but a 450r rotor and hub will probably need to be used
