    PASM: can one soften the suspension?

    Gentlemen, this is my first posting (in my life)
    I have a 987 boxster S with PASM, and it is too hard for Greek roads-where I live...Can one fit the normal shock absorbers in order to soften the car, or it is impossible?Dimitris

    Re: PASM: can one soften the suspension?

    Welcome to the swamp.

    It may be that PASM in non-sport mode provides a more compliant ride than the standard suspension. Do you have 19" wheels and tires? If so, switching to 18s may help. Some tire brands also provide a more compliant ride than others.

    Almost any switch is possible, but a proper suspension switch from PASM to the standard suspension might be somewhat expensive, but probably not as costly as going from the standard suspension to the PASM. The standard suspension apparently does have slightly softer spring rates (someone posted the spring rate graphs for the Cayman S here recently), but I don't know how much the shocks differ in their dampening rates. In short, I hope someone who knows more than I steps up to provide a better answer.

    Re: PASM: can one soften the suspension?

    You could for one fit springs from a non-PASM car - they are softer. There may also be some aftermarket offerings that have progressive springs which will also be more comliant. Finally, 986 springs may be softer and may fit...

    Kalws ton filo mas !!! poy meneis athina?

    a friend of mine has boxster s with pasm, 18 inch wheels and the ride is very soft to mine, which i have a boxster with 18 inch wheels. when he presses pasm, then the ride tightens a lot, as tight as i am. but, you should have a very enjoyable ride though with pasm, i know my friend does!

    Re: PASM: can one soften the suspension?

    Gentlemen,

    thank you for all your informative answers! I have already ordered a set of 18" Cayman S wheels with Michelin PS2s which arrive next week. From your comments it seems that this will solve my problems of too hard suspension (and a bad back). In case further improvement is needed, I will put the standard springs. In case a Greek friend is interested, I am selling the set of (unmarked-perfect) Carrera S 19" wheels I have now...

    I honestly don't think you're going to see a ton of difference w/the 18s. I have PASM+18s on my 987s and it's still pretty rough. If this doesn't work out for you, I'd suggest you go a bit further & try 17s. Search for a few threads on this in this forum.

    Re: PASM: can one soften the suspension?

    I just installed the 18" wheels (instead of the 19"). Now the ride is just perfect, on the imperfect Greek roads! I strongly suggest it the change to anyone feeling that 19" wheels, even with PASM on "normal", gives too hard a ride...

    Re: PASM: can one soften the suspension?

    hmmm, that did not work for me on the bulgarian roads (going from 19s to 18s on standard suspension). glad it did for you though.

    enjoy.
