I made a mistake a few months ago when I replaced my tires. I did the necessary research and learned alot - but apparently not enough. Because my Z is my DD and I dont (didn't) run it hard, I opted to go with the Goodyear F-1. Not a bad choice for putt-ing around town or whatever, and the cost is very reasonable (aka cheap), but at higher speeds or quick movements or lane changes... it's definitely not the tire for this car.
