That is the procedure for bump steer adjustment for a race car. Yes, it will help street cars. But should be overkill for what you are doing. It is not a normal procedure for this car and is not covered in the factory repair manual. That is just going to confuse you more.
I totally disagree that is the next step you need to do to you car. And no reason you needed to pay $$ to overnight the MP Race Chassis book to your house. And you really need a good measurement device or make one to get the bumpsteer right.
Your car should not need that adjustment. That would be a total last resort. You just want to get it back to stock and where the tie rod is not rubbing the T-bar.
I'll get some acuate measurments of parts tonight....
