Setting the toe-in at 1.4" as per the service manual accomodates the  factory bump steer.

I set my toe-in too 1/8" at static weight before the toe modification and took some measurements.

suspension fully uncompressed
2 2/3" Toe In

level a-arms to ground
1 1/8" Toe Out

suspension fully compressed
2 1/4" Toe In

So the worst part of my measured toe-out was 1.125" (1 1/8") toe-out.  Setting toe at 1.4" or about 1 3/8" lets the suspension go thru its full cycle, but never going toe-out.

This makes be believe that the factory wanted these quads to have toe-in all the time.... but we all know how the factory screwed up some things on the Zilla.
