Installed these shortly after buying the car second-hand. It had Michelin Pilots that were a couple of years old- still had some life left but they were lame. I didn't realize HOW lame until I bought the Bridgestones!
My previous G37 Sedan had Hankooks and understeered pretty badly. So did this new one with the Michelins. I assumed it was the car.
Then I had the Bridgestones installed the day before a terrible ice storm hit Tulsa. I got to test their winter performance immediately and was quite impressed. It was a couple of days before I got to try them on a dry road with no sand. In a word- amazed.
Very impressed with these tires so far. Their performance in the wet and snow is pretty astounding since they aren't winter tires. But in the dry they work great also. I'd definitely recommend these.
