[cheetah]

I have PSS9's set as low as I can go without spacers. I had it corner balanced with my weight in the driver's seat. Then I did my own alignment (made a framework and tools specific for this car). I also do not have any rubber in the rear suspension (adjustable arms, bushings not rubber, etc.).

I set mine at -1.25 degrees front, -1.75 degrees rear. Slight toe in both front and rear. If one goes 0 toe, it gets very touchy on the highway. With this setup, the bumpsteer was huge. Using a setup with multiple dial indicators and running the front suspension through its travel, I saw major toe out when the strut was compressed. That might have been good for certain tracks but was not good for the street. I created spacers to lift the steering rack away from the crossmember. With trial and error, I found the sweet spot. Now I don't get any bumpsteer throughout the travel of the front suspension. I think that it came out to about .4" thick spacers. Many people don't think about this when lowering a car, but it can make a huge difference in drivability.
