The pss have amazing wet traction in my experience. fwiw I've run the sport cups on track in the wet with good luck. This video was me playing around in the wet at roebling on them. Playing around with the throttle and weight transfer to try to get the thing to rotate since it was wet but still decent lap times all things considered. The car would run in the 1:17 range in the dry and these laps were in the 1:21 range for reference.
