Both 997S were with -20mm/LSD and PCCB, one car has X51(381hp) power kit(faster one).
Cayman S was with 19", PCCB and Sport Chrono.
Normal 997 with -20mm/LSD and PCCB would also be faster around Hockenheim and Nordschleife then Cayman S.
Guys, that is tha fact!
Also, all North American 997/997S cars can not have -20mm/LSD(sport setup) and this is the reason for not so excellent track times in USA.
BTW, I have Boxster S(987) with 19",PASM and Sport Chrono Plus and I am happy with it but, I have ordered 997S(X51,PCCB,-20mm/LSD etc.).
