Yeah, that makes sense. Haven't seen anyone selling curved vein rotors here.

Actually had to solid mount the carrier in the cradle as it flogged out the bushes. That's all that has been done, well except for wearing out everything every 12 months or so.

Is yours GTR(GTS-4) or GTS-T? GTS-T mount carrier in the cradle in a totally different manner and might be fine.

Keep in mind everyone that has raced GTS-T rear-end Harrisons have not had a problem so far.
