I use my Spyder to drive to the track, ride it there on surface is polymer asfalt or concrete and back. For general use the tires are great, on the track the F1 is phenomenal in the wet. The turn in response and the feed back when you reach the grip limit is great. It makes you feel very confident.
In the dry on the track the front outside flanks of the tires wear extremely also when they have heat inside them they get greasy and inconsistent. I changed the fronts after 3 track day's because the tread was showing. Never then less i am buying a new set of fronts because the tire is a great street tire and fits the car from a dynamic standpoint like a glove.
