gt3 997.1 knocking/rattle front end
as per title. my car is back at porsche hatfield. i have a knocking noise that occurs after about 45 mins to an hour of driving.
It sounds like a top mount rattle but I've been assured its not this. porsche have replaced both PCCB discs on the front, and also the back springs as one had a crack. the technician was adamant it was a braking issue rather than a suspension, because you only hear it when braking and slowing down.
they have called this afternoon and said they can hear the noise but do not know what it is!!!
can anyone help me please as this is driving me bloody mad!

Mike, you may want to check your shocks. My .1 did this when I first bought it (used); seller was unable to locate the source, just like you're experiencing. Turned out to be "death rattle" of the shocks. I'm NO expert, but the way it was described to me, the internals were failing and they would only start rattling like that after the shock oil had heated up from driving. Again, no expert at all, but worth checking...as it sounds similar to my experience.

My front shocks failed the same way, not worth rebuilding. I have a set of ohlins r&t Dfv coilovers for sale soon, only has 2 trackdays on them and will come with new front and rear oem top mounts. New was $4000. I will be listing for $3400 OBO + shipping
