I have -20mm and live in Nottingham and I would never own a PASM car while the sports option exists.

-20mm is nowhere near as stiff as a PASM in hard mode and the car feels so much more alive with it. I have driven the car all over the UK/Ireland and Europe and never once thought it too harsh. I did however drive a PASM in sport mode and found the ride stupidly bobbly and far too harsh for A roads where it felt like it wanted to jump the nearest fence and stick me in a field.

GT Purely Porsche have also just done an article in the 50th issue and cited the sports suspension as one of the 'must have' options referring to PASM as giving 'an artificial feel to proceedings, is less involving and ultimately less rewrading than the more conventional spring and damper setup of the sport kit'
