I finally got to get out and ride for the first time with the new Precision Racing stabilizer on Saturday. The install was pretty straight forward, only took about 30 minutes. That was taking my time and there were really no real surprises. Just of course make sure to check the full range of movement, stop to stop to make sure nothing is binding. The directions included are pretty good, and include some pictures. It was a much easier install then a Denton. The contact area between the frame and the main bracket is kind of small and there are some grooves cut in the bracket so I first wrapped the frame rails with some silicone tape to help the bracket grab without digging into my frame. I didn't take a pic, but in this picture from their website you can see what I'm referring to, where the mounting bracket attaches to the frame on each side of the stabilizer body:

The big feature touted by this unit is the seperate adjustments for the center and the sides. This is definitely legit and not just a marketing thing. Turning the center adjust screw and the side adjust screw definitely effect the center and sides seperately. The adjustment screw on the front is the center and the screw on the back is for the side adjustment. Based on the recommendations included with the unit, I set it up 12 notches out on the center and 14 on the sides. I didn't feel it doing a whole lot, I could tell it was on there, but wanted it to be doing more. We stopped and I decided to crank it down to 6 in the center. Huge difference, too much actually. It was defintely taking extra effort to get the bars started turning at all from straight, then they would give because I still had the sides on 14. I kept tweaking it and finally settled on 8 in the center and around 10 1/2 on the sides and it really started working great.
One of the best things about it is that it is truely adjustable, moving the adjustement screws actually makes a difference and since they are screws, it's pretty much infinitely adjustable. Also, you can easily turn them with only your fingers while your wearing gloves, so no breaking out tools. You can go from pretty much zero dampning to so stiff you can't turn the bars at all. If you want just a little more, or little less, you can turn them 1/2 or even 1/4 of a notch at a time. One of the things I've heard about the WER was that even all the way up wasn't enough for some people, there's no way that would be possible with this unit. Like I said, on 6 it took a solid extra effort to get the bars started turning, I can't imagine what it would be like on 3 or 4. If you like to tweak and fine tune, you'll love how adjustable this unit is.
The only other stabilizer that I have a lot of experience with is a Denton, and this unit is far superior. The biggest difference is in the total feel and how smooth it is. With the Denton, it always seemed like a trade off, you pay for better straight line stability with stiffer steering in turns. With this one I definitely felt like there was more of a balance, I could get the straight line stability without too much addition steering effort. In terms of the Denton, when it was new(they seem to start fading pretty quick), I would say it was like having it on five in staight line, but only on two as far as addition steering effort. And it felt much much smoother then the Denton in both situations. Of course it does cost 3x as much as the Denton, so in a way it's not that fair of a comparison, but unfortunely I don't have a lot of experience with the WER or GPR.
So far I'm happy with it. I guess no stabilizer is intelligent enough yet to know the difference between the wheels trying to turn on their own from hitting something and you turning them on purpose, but this unit does a good job of adding stability without a ton of additional steering effort, which I guess is all you can ask.
Just an FYI, I am still on stock shocks, so they were doing a pretty good job of beating me up all day. Once I get some aftermarket on there very soon, I have a feeling the feel and performance will get even better. Here's there website for more info:
