997 gts clunk on full lock

Is this normal happens when I pull of the drive.i am sure my old c4s used to do this too

My 981 GTS does this, which is due to the tires and a phenomenon called the ackerman effect.

My 997 GTS also made a noise at low parking speeds when on full lock, got the geometry checked and it still did it but less so. Sounds like the tyre scrubbing across the surface and I believe it effects a lot of Porsche and is down to the Ackerman effect.

Tyre scurbbing certainly is a feature on 911s, but it may also be a sign of very minor wear on track rod ends or even strut top-mounts or bearings. The top mounts can be in a pretty poor state without exhibiting many symptoms, other than in extremes - i.e. full lock or very hard (track) braking.

Thanks guys thought is was nothing to worry about

more of an issue in really cold weather

My 991 did this until last week.
Then fitted winter tyres and now scrubbing/clunking has gone.
