Three brand new C2S test drives and
2 of the cars had a terrible shimmy in the steering wheel @ 50mph+/- and one was perfect, these were brand new cars with less than 50 miles? The tires were Pirreli, Conti and Michelin.
I really hate a steering wheel shimmy, is this a common problem for the 997's?
Thanks

Sometimes you got to wonder if the dealers check the alignment when they get them. I would tell the dealer, if I really liked the car, it's a deal breaker if you can't get the steering straight. Especially in a Porsche.

How many miles did you drive these cars? Some dealers are careful not to let people take their stock out on joyrides and the tires wind up flat spotting. It takes a few miles to get them round again.
Owners are encouraged to return their cars shortly after taking delivery in the USA for wheel alignments,--things can get out of wack enroute chained down on the ships.

My dealer inflates tires to 57 PSI on all the lot cars. As hot as it is here, they flat spot terribly ... not good for test drives. So whenever you want to go on a test drive, they pull the car off the lot into the service bay and deflate the tires. When you are done, the inflate them again. Sounds like a lot of hassle.

I really hate a steering wheel shimmy,
A lesson I learned from the school of hard knocks is to never buy a car with a steering wheel shimmy because you believe that it's no big deal correcting the problem. Maybe in the majority of cases it's no big deal, but I can attest to the fact that some are real challenges.

The dealer gave me a new Cayenne for a loaner (60 miles on it) and it had a nasty shimmy at highway speeds. The wood steering wheel option didn't help my annoyance of the problem either.

Interesting thoughts.
I am a bit confused though on what alignment has to do with a steering wheel shimmy as the cars I drove all tracked straight.
Balance being off, tire flat spotting, a tire being out of round, a bent rim, a steering rack or suspension problem seem to make the most sense to me as potential causes of the dreaded steering wheel shimmy.
I just hate it when you pull off the lot in a brand new car and the steering wheel starts shaking side to side like a washing machine's agitator. It seems some car are much more suseptible to this problem than others and some tires are also worse than others.
So for those that have had their cars for a while now is it safe to say that this is not an issue with 997's? And with respect to flat spotting, do you still have to drive for a few miles to get the flat spotting out after the car has sat overnight or longer?
Thanks

Most probably tire flat spots. Run it for more miles and as they get hotter the shimy magically goes away. I experience this on my cars, especially the 5000+ lbs. Cayenne, after returning from vacation while the cars have sat in one place all that time.

And, the vibration lessens and lessens until you suddenly notice that it's gone altogether.
