IMHO I don't think it is the Z itself that doesn't like rain, but the fact that we put on high performance tires that seem to have the rear tires wear out quickly for some reason
It was raining/snowing today and my Blizzaks were very solid. Also, when I put on tire from now on I will always put on a complete, new set. Sometimes the fronts will last twice as long as the rears, but to me that is dangerous in the Z.
