New Boxter Clunking Steering On Full Lock
Discussion
Just back from my mates place after he kindly offered me a drive in his brand new Boxter. I pull out of his drive on full lock and the car violently juddered to the left. As I continued at a VERY slow pace the car continued to jump/knock until I straightened the wheel!
We looked at each other in shock, this wasn't a little knock, it was pretty violent. It did it on left and right lock, in forward and reverse.
My mate has subsequently phone his dealer to be told....'yes they all do that sir!'
Questions
1)Do they 'all do that'?
2)Is it a fixable problem?
3)Why wasn't he told when he bought the car?....from a VERY well known, established Surrey main Porsche dealer!

My 911 makes a funny noice, like the wheel hitting the arches on full lock when the tyres are cold, so did the newish (2012 I think) boxster I borrowed recently. Wouldn't say it was 'violent' though.We looked at each other in shock, this wasn't a little knock, it was pretty violent. It did it on left and right lock, in forward and reverse.

Dealer did say 'yes, they all do that Sir, it's the wheels crabbing when they are cold'.. or something like that.
I've now driven two porsches, so with my limited experience, they do indeed 'all do that'.

Thanks for the replies....So sorry about the misspelling of Boxster 
(I did know that was how it's spelt but forget!...Forgive me!)
So it seems they do indeed 'all do that' well all I can say is....They shouldn't! It scared the bejesus out of us!
Yes me too the first time - agree they should really mention that when you buy it! (I did know that was how it's spelt but forget!...Forgive me!)So it seems they do indeed 'all do that' well all I can say is....They shouldn't! It scared the bejesus out of us!
This happened to me when I had a new Cayman S to try for the day last Sunday. Sounded horrible as though something serious was happening in the drive train somewhere, however the salesman confirmed that "they all do that sir" and it was caused by the tyres trying to slip sideways - Ackerman, as someone has suggested?
They do all do this, yes. Perfectly normal. As someone pointed-out above it's to do with the Ackerman steering geometry (together with the extra camber that is imparted to the wheels in a turn) and very wide tyres - it causes the front wheels to 'hop' on full lock.
Generally speaking, it's much more noticeable when the tyres are really cold as the tread blocks/rubber compound won't deflect nearly as much to accommodate some of the geometry-induced tyre/suspension compression.
Stop worrying. Enjoy the car.

Was always curious what caused it as I get it with mine every time I reverse out of my driveway but always assumed it was just a "characteristic" of recent PorschesGenerally speaking, it's much more noticeable when the tyres are really cold as the tread blocks/rubber compound won't deflect nearly as much to accommodate some of the geometry-induced tyre/suspension compression.

Wait until you have to sell it to someone who doesn't have experience of Porsches! I had such a headache trying to convince someone that the car was ok!!!
The whole post was that it had been bought by someone with no experience of Porches!2.7 with £1800 sports exhaust upgrade....sounds amazing!
