Brembo Monoblock Caliper

Brembo Monoblock Caliper from GSXR750 has just arrived, first attempt to install had shown that the 300mm rotor of the ER6n proffed to be too small. Only 2/3 of the Rotor surface has contact with the Brembo Brake Pads. Further measurement shows that the 310mm Rotor from the ZX10R 08 09 10 will fit nicely onto this setup. Apart from that a longer caliper bolt is required as the original ZX10R 06 Bolt is about  5cm shorter.
So I'm off to the bay to scamper for a suitable ZX10R rotor.
