SamIAm is correct. Basically when the suspension compresses, the toe will change from zero to positive or negative toe. This sucks bigtime through bumps...
Wolf- yes. The little spacers that lengthen or shorten wheelbase will work. Instead of 1 .060" spacer, you could use 2 .100" spacers, or 3 .100" instead of one .030" spacer. Same thing.
