Juddering on Full Lock

[mwilson]

When I pulled out of a tight parking space yesterday, with the steering on full lock, there was a nasty juddering as I reversed. Has anyone any idea what this may be? The car has just been serviced so I suspect it might be the tyres catching on the wheel arches. All I know is it isn’t a TVR quirk, ‘cos I used to have a Boxster which did it – never did find out why.

Cos the row of cars behind me were very close.
