Another vote for Michelin Pilot Super Sports
If anyone is "on-the-fence' regarding the Michelin PSS tires, DO IT, you will not regret it. My wife's car picked up a 3/8" bolt in the left rear tire and since she drove the car slowly for almost 3 miles the RFT Bridgestone was ruined according to the tire shop. We ordered the Michelins and had them installed today. It's a totally different car with real tires on it. The steering is very light and precise, bumps do not shake the entire car like the Potenza RE50's and the cornering is just amazing now. These tires should be on the car from the factory.
Next we will experiment with tire pressures. The RFT 36/42psi is a bit high for non-RFT tires and we will go to 36/38 as soon as they cool off.
