I have the DRC race system. I put the steering stabilizer on last (after alignment). The Bilstien (sp? - I never can get i before e right) stabilizer induced a pretty extreme pull to the left. I am still trying to adjust the air in the thing. The air charge is so small it is a pain in the butt - just getting a gauge on and off releases a significant amount of air. My truck was tracking beautifully after the alignment from PAB here in Tucson (those guys are good). They were also interested in the KORE parts - I gave 'em Greg's phone number but I am not sure what came of it. They wanted my feedback on the system, and especially the steering stabilizer (they all rode in my truck while they had it, so they experienced the rest of the system). I was hoping to get it adjusted to the point that their alignment was not affected so I could tell them it was no problem. Still working on it.
I would personally prefer an alignment to do it's job, and a steering stabilizer to do it's job (only dampen steering inputs from the wheels).
