4.2 Rear disc size

[jammy_basturd]

Anyone know what size discs I can fit to the rear? I believe the standard size is 273mm, but Racing Green have a 306mm that they say is for all Cerbera models? I'm guessing this will require different bolts and spacers for the rear calipers?

Hand book says 306mm for a 4.2
