I think that the rotor size is more dependent on the frame/fork mounts and configuration.
On my bike the 180mm rotor is just too big and rubs the fork. So this is something to check for first.
Yeah, on mine, the 160 mm rotor is already extremely close to the fork. I doubt anything larger would fit.
I'd suggest op remove his caliper (just unbolt it), mount a 180 mm rotor to the wheel, and see if it fits.
