This was the problem I had with geometry. The wrong drag link length and wrong offset pitman arm were installed on the roller. That made the drag link ride on the hairpin, and really jam on right turns. Also note that the drag link and tie rod are not parallel.

After a lot of measuring, a discussion with Jason at P&J and some helpful hints from here, I bought a shorter drag link and a no-offset pitman arm. After modifying the caster a little to about 6*, I put it all back together. Some time ago, I also replaced the (darn expensive) polished/chrome coil-overs to bring the panhard bar more parallel with the front axle, replaced the USED steering box that came with the roller, and got the ground clearance back with some slightly taller tires. I'll get the toe-in set tomorrow then see how it handles.

Replacing perfectly good, but incorrectly applied parts sure is expensive.
