How have you guys, with these clocks, mounted them to the dash, Im after sinking them in sort of thing.

The case can be split into 2 sections, I was going to cut the outline out 2mm smaller then just screw it together either side of the carbon dash panel.

Yes that what I did with my zx10r clocks,you will just have to extend the mode and reset buttons,due to the thickness of the dash between the clock face and the back of the clocks.

split the clocks then cut the hole to the outline of the rear "smaller" section then screw together around the dash, you will need to attach/glue a spacer to each button contact the same thickness as the dash to get the buttons to function correctly
