Re: Steering wheel vibration/shudder at 60mph+?
If you're braking while getting shudder your rotors or discs have corrosion. If you're not braking then your wheels are not balanced, your tyres are unevenly worn (only possible if you track the car and switch ABS off), or you have a suspension problem. As a long shot it's possible your pads are binding to the discs/rotors. I would check this fairly quickly. 911s aren't designed to be driven under 60 on the open road!

Re: I would also check to see if your wheels are round

If yoiu hit a pot hole hard enough it is easy to bend a wheel or wheels. I would take it to a tire shop, and get them to check the balance and they can tell you if you have problem with the wheel.
1) Tires out of balance
2) Flat spot due to braking (anti-lock does not prevent flatspots 100% of the time.)
3) Bent wheel - I went through this - Porsche wheels bend easily, hard to spot (will balance just fine) but can be repaired most of the time.
4) Wheel bearing failure - not on a 997 unless you have been driving it non-stop since you left the factory.
If the balance is correct then most of the time it will be a bent wheel.
Good luck!
