    Ignorant/stupid Question EAS ?

    For those with some engineering nouse..Is it possible to locate a smaller suspension spring around the bump stop that would act as a shortstop suspension measure if the car goes into hard EAS fault. If a spring was made short enough to only work when below access mode would make getting a disabled car home with a lot more comfort.

    Is this a stupid idea? Be kind when answering.

    Sounds like a perfectly reasonable idea Peter. I can see no reason why it couldn't be done, other than the challenge of where it is mounted so as to not interefere with standard running gear.

    I'd like to see somebody develop it in to reality.

    Cheers, Paul.

    If mounted over the present bump stops, they would need to be a very short and thus very stiff spring which would, in my non-engineer opinion, be prone to breaking or damaging the chassis.

    My understanding is that the bumpstops are designed to act as springs albeit very uncomfortable ones on a long trip.

    I was thinking the same thing after seeing Keithy's effort.

    I pinched some bump stops off an early Urvan to use on another car & they were designed to be partially compressable - like a 2 stage bump stop.

    I wonder if something like that would at least make the ride bearable if/when the EAS fails.



    Maybe even something like this:

    Would the chassis take larger bump stops in a more pliable material? That may help, wouldn't it.

    May need to adjust the height for access mode...

    well it may be one of those "nice if it could be done" ideas.
    Seems a shame that with such a comfortable suspension that we get to ride on rubber if there is a problem with the system, sure the RR engineers would want the car repaired straight away as would we owners but as Keithy and many of us have experienced ...it can be a long way from the repair shop or home and a shame they didnt put more thought into the limp home mode. I will make some inquiries at some suspension places and see if anyone can help put something together to suit or offer some suggestions.
    Thanks for the feedback

    No such thing as a stupid question, only stupid people :-)
    Could it be developed as an emergency get you home spring? I recently clocked over 200kms on a 3 spring dash for home after one of the buggers blew: Okay'ish albeit a bit rattly, thank god for separate air valves. Would have hated to do 2kms on bump stops, let alone 200

    EAS bypass with switchable valves would make a survivable drive out even after losing a bag.
    Hoo-Roo,
