I am on the verge of going crazy trying to get road tires.

Would it kill me if I were to down size the rears from 325/30/19 to 305/3019?

Subscribed. I'm hoping Michelin PSS will come in our size next year.

I have to deal with tropical rainstorms when I am on the road.

I am sure the Supersports will come along. But I can't wait.

I've literally just been down this ugly road, and unfortunately the answer is, on our 12x19 wheels (my GT3RS is the same as your GT2s) the only tires you can use are the SportCups that you have now, or the Pirelli Corsa System.

Trust me when I tell ya I've tried every possible tire company and resource to answer the question.

(In-fact I wrote a complaint to Michelin this morning telling them to remove the darn GT3RS they show for the SuperSports if they dont produce it for the car, as false advertising. They did actually reply back with an "we are sorry.....blah blah blah" and they would have marketing fix it).

Get the generals off Tirerack.
Zero grip in the dry (I have to put track wheels on to bed brakes) but excellent for mudding and monsoon rains. Cheap and they last forever.

This is the only thing stopping me from getting a GT2. :/
