How high (or low) will affect the steering on the amount of steering throw vs. the shock travel (during the travel of the shock, the toe-in/out adjustment will vary). Bumpsteer is an adjustment commonly used on Off-Road cars and helps on bumpy tracks. Sometimes better to not mess with bumpsteer...
Other adjustment possible with those new uprights is the wheel offset. The handling is different if the wheel sits inner or outer on the upright. I can think about the difference in handling regarding the offset, but after the shock of hearing that hard chassis improved traction on loose tracks, better to try by myself what does the offset change.

So is that the suggested starting point with the new parts? (.5 spacer to outside and 1 mm shim under steering link)

Thx. so the new "standard" set up will be lowering the ball link height on the steering arm relative to the original parts. I wonder what effect that will have on bumpsteer and steering.

I tried to figure what's happening when you modify and lowering the position of the steering link connector you're modifying the toe-out ratio vs. the shock travel (I could be wrong... but what I visualized is a small decrease of the toe-out of that wheel. In few words, the most compressed is the shock, the more inwards turns the wheel). Don't expect a dramatic effect. On those machines a 1 degree difference is really huge.
Maybe those parts make the steering faster (and could be.. more delicate). Better to not adventure what will do those parts until assembled and track tested. Anyone has available at their LHS? Tested them?
