The "Split at Data Point" feature could be set to 60 here, with a Relative
Angle of about 90, but that will still maintain the large and small tick intervals (and numbering intervals) throughout the entire range of the gauge... There will just be a different amount of space between them before and after that split point.
For something this customized, you may be better off bringing in a background image that has it setup the way you want, and then using RaceRender to overlay just the needle onto that image, as described by Option 1 here:
