honestly ive never had that problem with spinning out. my car will break them very easily in the rain, but i just back off and itll barely wiggle sideways. from my experience with tires, the cheaper tires have worked best. michelin xgt z4's sucked and have been the worst tires ive ever owned (and theyre damn near $200 each), stock 99+ gt goodyears werent much better, nitto dr's have been ok, and my no name $80 tires i run now have been the best, wet or dry.
i live in florida where we get rain nearly everyday in the summer. all i do is be cautious when pulling out into traffic, and accelerate about as fast as a dump truck so i dont light them up
