Bob do you mean keeping it inline with the body when the wheels are just slightly out of line with the body? My plan was to keep it inline with the wheels horizontally but allow the wheels to move vertically. The skirt itself and the pivoting attachment point at the top would have to be strong enough to not bend inward or outward in the wind.

To transmit the turning of the wheels i considered either A a pair of roller bearings located on the inside front and back of the skirt touching the tires large sidewall, or B a linkage from the top pivot over the tire and down to spindle near the joint. The linkage would articulate in several places so it would allow for vertical movement of the spindle but would transmit the horizontal rotation of the spindle.


edit2: I think the wheel move slightly in or out with suspension movement. That would also require more of a gap and maybe favor the linkage option.
