Following up now that I have some hours of serious road time on the bushings.
Still recommended. I do have one warning: slow down! Or at least watch for cops. My shotgun seat passenger commented that I was driving a full twenty-over instead of ten, on one curvy road that we frequently take.
I did not even notice. The car just feels that much more substantially planted and solid and pointable. Even at straight-line freeway speeds, it feels more competent than before. I am very impressed.
Note: I also installed one of the two transmission bushings that came in the kit. It isn't that perceptible to me in over-the-road live shifts, but it does seem to have reduced the can't-find-reverse problem that sometimes shows up in cold Integras. I'll do the other one and see if I notice more.
Oh, still no squeaks, even on really serious speed bumps and the like.
