These have been out for almost 2yrs now(in N. America). I'm usually not a 'Firestone guy' but I think they have a real winner with this one. This tire is quickly becoming "the best kept secret" in modern Summer performance tires. While it's labeled as the "Indy 500" in N. America, it's known to the rest of the world as the Bridgestone Potenza RE003 Adrenalin. I've had these on my `06 Audi A4Q since March and they've completely changed my driving experience. They offer a level of grip that's typically only associated with Ultra-High Performance tires costing twice as much. The dozens of positive reviews on TR hold weight here...it's a legitimate contender.
