I also started out with the same all season 235/50/18 Pirelli P-Zero Neros on my Pony package and found that heavy rain did not lend to stability. I can only imagine a stick would make it a little touchier.
I used to run Cooper Zeon 2XS tires when I use to autocross in the rain and was sad when I found that they don't make a size for our cars.
I did however find these Nexen N3000 255/45ZR/18 work quite well.
Any tire on any vehicle traveling over 70 MPH rolling over water can hydroplane. (this actually varies with vehicle weight, speed, tread pattern, and water depth)
Granted some tread patterns help evacuate water but once you get above about 70 MPH regardless of tread pattern the water simply cannot be directed out from under the tire fast enough and that means the tire has to roll over (float over) it. IE: Hydroplane
As someone else pointed out you came from an AWD and are now in a solid axle rear drive car with enough engine to spin in the rain easy, just learn the limits somewhere safe!
