I'm probably one who you read this from; at least the part about tramlining. I've never felt a "smoothing of the ride". I didn't come to this conclusion through a thought process...it is what I observed. At the time, I was playing with tire air pressure. Every day I would add a pound or two in various front/rear combinations before I went to work. One stretch of road I drive every day is particularly prone to tramlining. As I went up in front pressure, starting around 38 pounds, I noticed more tramlining. 39, definitely more. 40 pounds at 65 mph on this strech and I better be paying attention with both hands on the wheel. Settled on 38 pounds for the front. At about this time, my brace arrived. The first time I drove this stretch with it installed I noticed less tramlining. Curious, I started pumping up the tire pressure a pound at a time again. Got up to 41 pounds and never did feel nearly as much tramlining as I did even at 38 pounds without the brace. (And because someone will ask, I've now settled on 39 for the front, 38 pounds in the rear.)

Anyway, I'm not saying this was a scientific study; other variables could have been involved. Just my observations. Take it for what it's worth.
