Ackermann steering geometry is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii.
there is nothing Porsche Silverstone can do it's simple maths ;/-) all cars do it, tyres can make a massive difference to how bad a car is on full lock.
All my Porkers do it, more so in reverse as I never have a need to do full lock going forward.
I would expect that's what the noise is imo. if Porsche are stuck for a fix and your car did not do it before, get them to fit a set of loan wheels with new tyres on see if that fixes it.
it maybe just worn tyres showing up the Ackermann angle issue.
Ofcourse it might be another issue, but the Ackermann effect on the wheels might be causing a worn bush to knock under this extra load, on a 11 year old 50k mile car it could do with a bush refresh every where anyway imo, also check the top mounts.
Loads to go on , not sure why Silverstone are stuck with a simple problem.
