anyone running them?  how are they?   Did you run PS3 or PS2 beforehand?  or Bridgestone Potenza RE-003? The hype is that the new Michelin Pilot Sport 4 tyres are sh*t hot, and better than the PS3 before them.   Still, Bridgestone are out with the RE-004 soon too... at least war this isn't Betamax vs VHS! Your experiences appreciated.
