I am pretty sure that every post above mine has not run the 555r2. It's actually a very streetable tire, that handles good, has great traction, and will last 10-15k miles depending on how hard you are on them. They have more tread depth then the original 555r that I ran prior and I still got 7k miles out of them with lots of dig runs. I currently run the 555g2 front/555r2 rear and it's a great combination. I don't road course my car but I haven't had any issue taking corners at fairly high speeds.

That being said if you daily drive your car and will road course a couple times a year, the MPS4 as mentioned above is probably the best all around tire for that. But I still don't believe you will get much more mileage out of any tire because you can not rotate them and that drastically reduces tread life. You will be replacing tires every 15-25k miles tops on these cars with spirited driving.
