Well, I very carefully set up my toe and camber (all to 0). It seemed to help a lot. I was able to go full throttle down the back stretch last night without incident (aside from the crazy driver). My turn in wasn't that great but I can work with that.
For me, I say this was the biggest contributing factor in getting mine to steer straight. I am going to run on an asphalt street tonight (where I would see the most torque steer) and see if my adjustments helped there as well.
I had the same problem with my stock settings (and I'm sure the rally tires didn't help). But once I dialed in a few degrees of toe-in in the back, toe-out up front, and some negative camber all around, it was much more stable on asphault. Of course, funky tire wear seems to be a nice side affect.
