    Re: My PASM in sport mode is too rough for street driving.....

    As far as I know we can't get the 20 mm chasis in Canada. However, even with our rough city streets here I prefer sport mode turned on rather than off. This must be why Porsche has so many 911 varients - something I couldn't understand before. I do wish the 20 mm were an option for us though.

    Has a reason been given by Canadian authorities as to why they do not allow the 20mm chassis? I assume in the US height is the issue but I cannot imagine it being lower than the CGT or GT2.

    Regarding bouncing sideways at speed, I had a similar experience while driving the CGT. Chassis is extremely stiff though I understand it can be moderated. Is that possible with the 20mm?

    PASM vs -20mm Spring rates

    Spring rates ft.

    PASM= 33 N/mm
    -20mm= 36 N/mm

    Spring rates Rear

    PASM = 56 N/mm
    -20mm = Progressive 60/90 N/mm

    Stabilizer Bar

    24 x 3.8 mm (same for both)

    19,6 x2.6 mm (S same for both)

    Re: Harsh critics on Sport chassis and Sport chrono

    Interesting Trundle, thanks
    So the -20mm springs are significnatly stiffer while the dampning of the PASM is just as stiff or even more than -20mm. I would interpret that as in the PASM when functioning in sport mode has spring rates that are too soft for its sporty dampning (since they don't even match the -20mm spring rates) in order for the springs to still allow a failry confortable ride in normal mode. If spring rates were higher (like in the -20mm) them PASM in normal mode would still be too stiff for normal mode since the springs would be stiff. This decreased matching in sport mode will hinder performnace and handling of the PASM compared to the -20mm which has stiffer springs to match. That would make sense to what we were saying before...

    The LSD would play a larger role on low-speed tight corners and also on slippery surfaces, no? great for the street performance and maybe not as much on a fast track? what do you think?

    Would also help in braking later for the corners, since a clutch-type LSD increases stability at corner entry
