Yea I just thought of basically what you just said. My car, as it sits now, handles awesome on more open turns (50mph and up) rotates no problem. It is the tight stuff which it just doesn't have quite enough rotation. I might get the tri-point bar and just leave it with 0 preload for driving around town, then when it comes to an event add in the number of turns needed to get the toe to 0. Since it is so easy to adjust that wouldn't take much, plus I could even adjust it on the fly between runs if I had to.
One end of the tripoint bar is right handed threads and the other is left correct? So you just have to spin it like like a turnbuckle to adjust it?
When I said before getting some more rear toe out, I meant to toe it out to 0, not to actually have toe out. I doupt it will need that much.
