Just so we're clear, you did experiment with adjusting the rack damper bolt in and out to find the best spot to lock it down? And you did so after 15 minutes or so of highway speed driving, with the car completely warmed up?

As I think I mentioned in response to an earlier post of yours, you have to experiment with the idle speed and the rack damper adjustment in tandem on some cars, to get a smooth idle.

What is the idle speed of your car right now?
