My Project X bullshit detector went off (again), so I figured I would clear some things up.

Suspension travel on Project X was limited in the upward direction simply because the 33" tires were hitting the body work, the engine swap and steering components had nothing to do with it.

They limited upward travel by about one inch.

Dropping the pitman and idler arms did not cause any problems.

They dropped them by simply stacking 2 arms and welding them together, and removing material on the high end of the link side, and the low end of the frame side.
