I just got my Goodyear F1 GSD3's on last week. I bought them when they were $88 at Tire Rack and just put them up until I needed them. I wound up with new wheels and my Kuhmo 712's had lost their wet grip, so I felt it was time.
The temps here have hardly climbed out of the 30's for days, so I can't tell for sure how they're going to grip on warm pavement. My guess is they're going to be insane. I finally went balls out on an off ramp tonight and couldn't really find the limit. It was definitely an improvement, even in the cold. I also suspect the sidewalls are a bit softer than the original Potenzas or even the 712's, but I can't say I mind. This tire is not only quieter than what I'm used to, I can tell a noticeable difference in the ride quality now, at least over minor stuff.
