Have a 2-month old 60; 19" wheels/Goodyears, standard suspension; ~2000 miles. It's my DD and I just took a ~650 mile trip in it.
Absolutely LOVE the car, expect this problem...
Problem has been there since day 1 - no change 2 months later. 42psi or 45 psi all around - no change. Steering wheel settings - no change.
It's a strange feeling. The car doesn't feel stable at freeway speed on sweepers, on-ramps, off-ramps... The feeling is similar to (as described by others on this forum)... 'busy steering' or 'hunting'. The car never seems to settle into a turn and requires continuous steering input, and especially steers itself with *light* accel or decel. Definitely not talking about heavy throttle inputs or sudden lift-throttle scenarios.
It also happens to a lesser extent driving straight on rough freeways. I'm not confident driving in the fast lane on the very narrow-laned SoCal freeways for fear of scrapping the K-wall.
I'm not sure what the root cause is:
Alignment? Too much Toe-out ?
Tire-tread and sidewall squirm ?
Lack of roll-stiffness ?
I don't believe it's the 'loose rear suspension' problem discussed on this forum. The car feels ok when driving aggressively at lower speed, when you need to stay on-top of the steering. The scenario's i'm talking about you shouldn't need to stay on top of the steering.
Could really use some advice on what this could be.
UPDATE: Checked Alignment: The Good, The Bad, The Ugly
