R to X Conversion: you can do a complete wheel and front brake swap from an X, this is recommend if you do not plan on switching back and forth between setups, although switching is still possible it wont perform as well. Alternatively you can get a set of 17 inch rims laced into a Warp9 or R hub so you can easily switch rotors over between rims or buy the EBC/Warp9 320mm rotor and relocation bracket for best performance on road and still able to use the 250mm offroad, either will not require switching calipers when you switch wheels.
X to R Conversion: you can do a complete wheel and front brake swap from an R, this is ONLY reccommended if you don't plan on switching back and forth as there is no 250mm rotor for the X hub. Unfortunately because of the X caliper your only other option is to use the Warp9 300mm rotor (available in floating and non-floating) on a Warp9 or R hub.
