A bargain at Camskill at the moment, I have 2 arriving tomorrow for the front
Now, to the OP, don't "buy a splitter", get the problem sorted out. Sounds like bushes, or tyres, or something else from above.....

I know these cars to be excellent tourers, and that is why i'm not comfortable with the way it behaves, the car just does not seem to be happy on motorways.
The issue is not tram lining as I've tried moving away from the "most used" part of the tarmac, same issue.
Even My daily Audi A1 is a hell of a lot happier at 120mph on the motorway, and I'd expect the C4s to be alot better than Audi's baby car.

Don't suppose this guy was the driver of the 991 by any chance?

Piranha-- said:Hi,
Have been having an issue with the '06 C4S for a while now, and I cannot seem to get to the bottom of it.
Car handles great on track and curvy roads. Steering is precise, accuracy is great, and steering feels very sharp. The car really inspires confidence in the twisty bits (even bombing through long corners at 100+mph).
Driving on motorways at approx 70 mph is ok, but anything higher that 100mph and the car feels twitchy and the car does not inspire confidence. tried both sport on and off, inc pasm on/off and all combinations, but nothing seems to fix this. It feels like steering inputs are amplified at high speeds making the car nervous.
Tires are porsche spec (N) Michelin Pilot sport
Alignment has be adjusted to Porsche spec with 0 tolerence
Wheel balancing is perfect.
What else shall I look at?
