    OEM LSD retrofit possible?

     Hi All,

    Any Porsche techs out there know if it might be possible to retrofit the new factory LSD(ABD?) to previous 987s?  Mines a 3.4 FWIW..

    The factory part is a clutch-type LSD apparently provided by Guard. Check out their web-site at  www.guardtransmission.com under Products and Cayman & Boxster Diffs.

    I am pretty sure it can be retrofit. Send them a mail and ask.

    I'm pretty sure there are suspension tweaks on the factory LSD equipped cars as well though


    Re: OEM LSD retrofit possible?

     Yes Dave, you better drop that KW rubbish and get some proper suspension

     Like your re-spring-ed stock stuff?  Yeah right.. I prefer not to bounce off while going round the corners :-)

     ..there I was, reading the thread in OT about the lack of non-OT content, thinking I'd try and spark a bit of technical discussion.. duh.. some people..

    Re: OEM LSD retrofit possible?

    From my understanding, the OEM LSD has a very modest locking rate and I am asking myself about the advantage over aftermarket systems. There are some LDSs for the 987.1 on sale, but I assume you know that already. Smiley

     


    Re: OEM LSD retrofit possible?

    Hmm, interesting.. I'll do a bit of digging and see if I can find out the specs on the OEM unit and see how it compares with the aftermarket ones..

    Cheers,

    Dave

    Re: OEM LSD retrofit possible?

    Also check posible posible incompatibilities with the PSM, AFAIK that is the reason for the modest locking rates of the factory rear LSD on 987 and 996/997 carreras that had PSM.

     The OEM differential has a 22% locking under power and a 27% locking on the overrun.

    That really is a good subject for a technical discussion. Smiley

    Now I feel really bad about not being able to answer your question. Smiley
