It seems to bounce around a lot like my car when the PASM shocks wore out.  ?  Is it just me or does it bounce too much in the rear.  Can't believe the roads are that bad.  Other cars around it are not bouncing at the same speed.  Watch carefully.

Maybe PASM is switched of? Such "hopping" can even be caused by very sporty (UHP) tires like Michelin Super Sport and/or driving with Sport Chrono activated only (that's what I've noticed while driving with a 991 Carrera S and 987.2 recently)
