Michelin Pilot Sport PS2 are on my ISF from the factory. In my opinion having driven ISF's with both tires, the Michelins are much quieter and grippy compared to the Bridgestones. The RE50A's are louder and seem to spin a lot easier.
Very true! I'm not going back to Bridgestones either...I have the Bridgestones and will not be going back to them. I was quite suprised on how easy they lose traction on dry pavement.
