Further notes: The A/S3+s are much lighter on center than my snow tires were. I don't get much weight in the steering wheel until about 40mph. I ran the car pretty hard through some twisties last night. They have plenty of grip. Sidewalls are not laser sharp, but plenty responsive if I'm not being hamfisted with the wheel. I prefer laser sharp, but you can't have it all. The car didn't pause before taking set on turn in, but mid corner adjustments were a bit squidgy. I haven't launched the car, but I have panic braked and the car stopped hard without any drama.

 

My Goodyear Eagle F1 Supercraps are gone. My new Michelin Pilot Super Sports are noticeably better immediately leaving the tire dealer.

 

Yes they are.
