Grant, keep in mind, after you lift your VX your axle will shift a little more to the right due to what I stated before. It might be negligible. You might want to double check the clearance between your drivers side tire and the frame and what not. I might even suggest flexing your VX out to see how close the tires come to rubbing when one side is compressed into the wheel well. A simple fix might be to cut the panhard bar in two and sleeve it with a larger diameter tube to lengthen it. <shrug> I would suggest replacing it though, because maybe the tracking issues you had before weren't just from your tires, but were worsened by the axle being slightly askew. Lifting it might also worsen your tracking problem and increase the risk of an accident. This is all just speculation of course but I think it is something to think about. Keep us posted!
