I was following a S14 drift car with 17" wheels on LDP few years ago. It definitely had some semi slick. And it was raining quite heavy. He was on lane one and the car was floating left and right at 60km/h. To be fair the car is RWD had all the interior removed and no idea how much tread is left or the brand of tires it was on. It was aqua planning at that speed. Still i would not bank on driving fast with semi slicks no m atter how sticky they are in the dry.

The one i saw was blue with the bumpers still intact. I am sure it was S14 and not S15. From puchong heading to sunway.

Long time ago when i was hanging out with toyota ppl in ZTH, the SEG guys was raving about Advan AD05. Even then they were saying wet is not really its strongest suit.
