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?
