My car is set up for the track and these tires are used for HPDE and rain conditions. Wet and dry grip is excellent for this tire class/treadwear, and the car is extremely predictable in corners. The S-04's approach the limit quickly but there is a wide margin of slip angle between driving fast and losing grip. Great tire if you need to drive on them to and from the track or autocross. I'll keep these as a rain backup set, but have moved to slicks for primary use since this is a track-only vehicle.
