After several thousand miles of having my rigid collars installed, they are still the best improvement for the money/time spent that I feel I could have done. My Contis are getting "worn" due to my aggressive driving style. And, even with worn, mid-range quality tires, the ride is still much improved!
Bumps are noticed but not transferred to the steering wheel as dramatically. The steering wheel doesn't "shimmy" when hit with uneven bumps like before. The overall feel of the car is still improved with regards to smoothness.
I live on a street where the city just doesn't maintain the road properly. I used to go out of my way to avoid this stretch of road because of the harshness. I am not as concerned about this stretch of road now.
