Near where I live there is a 45 degree sweeping left hand turn. Twice now when straightening up exiting the turn, the rear right has stepped out. Easily corrected but it shouldn't do so and hasn't in the past.
The car has dry adjustable suspension with settings as recommended by experts here and elsewhere running good Yoko A008's. What should I be looking for to diagnose the cause of this problem? Usually the car has excellent, predictable handling.
Thanks.

How much toe-in are you running? Any amount of toe-out will cause this.
Maybe the trailing arm on the faulty side has excessive wear. Easily checked by jacking up the rear wheels, handbrake on, and attempting to rock wheel back and forth.horizontally.

Toe in is (supposed to be) 1/16"
I'll check the trailing arms.

Same thing happened to me last week in my van on a right hand turn roundabout. Turned out I had not checked the tyre pressure for a few weeks on the LH rear tyre. Just a thought
