I may have a different opinion on bump steer than most everyone else. When the cars are stock they handle so poorly that bump steer is just part of the poor performance. I can't tell you how much. I have not driven a stone stock mustang in 20 years. The mustang I recently completed was purchased disassembled. I put it together with mods recommend from this website and others. I am very happy with the handling performance of my car. So much so, that I hope to take it autocrossing soon. To date, I cannot tell you that there is noticeable bump steer. I also have not really pushed the car to its' limits yet either. It's hard to do that on public streets.Thanks for the tip, but I'll give'em a few days before I give them a PM.
Yeah, this is about building your own rack&pinion, and it is a system similar to the Steeroids systems (only better ), the rack is quite different from Unisteer from what I can see. If i didn't misunderstood some of the important stuff in the beginning, the "J" car rack will perform very good regarding to bump-steer aswell. How is yours Unisteer regarding bump-steer?
