I also have a 19'' set up with standard suspension. I find the ride excellent. Firm (the way a sports car should be) but never harsh except over the very worst bummps. Ona twisty back road at high speed the handling and ride is exemplary.

I test drove the car on 18's with PASM, but can't really say I have felt a significant difference. For me, the standrad tuned Porsche chassis setup is every bit good enough. There have been a few complaints about a rolling motion on the back with PASM. Obviously the standard (and improved on the Cayman) suspension should be superb.

Cheers,
