Hello!

Have you checked the tire pressure?

What is the condition of the tires? If they are new that is a fairly common. There are also some tires that track differently than others even once they are broken in. For example, "squirrelies".

Alignment might also have a role to play.

Have you checked to see if the car has any loose or worn suspension components?

I would get the alignment checked first. A small amount of toe-out on the front or rear can hake the car feel very nervous. If it feels twitchy on bumpy roads, also think about reducing the negative camber to the minimun setting, but the trade-off for this is a slight amount more understeer. I'm talking road use, by the way. Track day gods will be rolling their eyes.

And how old are the tires...from date of manufacture.

Tires are continetals (orginals porsche) they are a year under they car, (drove 15k now)

Tire pressure for your car is: front 2.0 bar and rear 2.5 bar. Alignment should be done with a full fuel tank !

Could it be tram-lining? Where the type of tire you have follows little grooves/ruts in the road making it feel like it has a mind of its own? Mine did this on the Michelin Pilot Sports even after I aligned it myself but doesn't on the current tires with no change in the alignment.
