On a side note, if you aren't too concerned with treadwear and your only concerned with performance, I would recommend the Michelin Sport Cup. This is the same tire that comes standard on the Viper ACR's and it is an amazing tire. Incredible grip and good performance on the street. However, they don't last long.

Agreed! My ACR sticks like glue.
