I agree. Up to now I consider what I have done to be the course adjustments so now comes the fine adjustments. I have to admit I am not sure where, but am determined. I bought a laser measure to make measuring easier.
I believe I have found the resolution. I have not been able to get less than .55 regardless of what I tried. I have adjusted in all directions and even made everything worse. I played with a tool at Racing Aspirations and came up with a base set up which got me back to the .55 which is very noticeable without even measuring. I found an article authored by the guy that used to build Revenge Sand Cars, I think his name was Jason. Over on GD they used to make a lot of good comments about his building abilities, but he did screw a lot of people out of money. In the article he covered the "bump steer bracket" for the rack as the easiest way to correct for bump steer. The bracket moves the mounting points of the tie rod to the rack outside the mount points of the arms. I decided to try it and made a temp mount for the tie rod that was 1.125 wider. After cycling the arm I was amazed that the bump steer seems to be minimal now. I do have to rebuild the upper arms as the builder did not make them long enough to the front of the car. That was also part of the problem. I have a lot going on so might be a couple of weeks before I can get back to it, but will update when I get it all back together. I hope I can get it to 1/8 or less. Sorry for the long post, but I became very frustrated that I couldn't make any progress and am elated now that I seem to have made some. Time to grab a beer and celebrate!
I will not make the May gathering. I need to use any free time I can scrounge up to work on the buggy so I can get this running this summer. I need to stay focused so I can make one of these get meets and actually have more than just a quad. Things should start picking up speed. Wahoo!
