Well... How about almost 20s faster Ring time!? Rememeber 997 Carrera S(-20mm/LSD,PCCB) Ring time by Sport Auto 8.05min. 997 Turbo time will be around 7.48min with normal Michelins and 7s-8s faster with Michelin Cup's or Pirelli Corsa's(YES! Pirelli will offer N-rated Corsa's for GT3/GT3RS and Turbo). Of course, we are talking about manual 997 Turbo with optional LSD.
