Notes: trying new front spindles modifying upper control arm bolt-in location, to help with roll steer. Set camber/caster and measured bump steer, best was with outer tie rod mounted to the top of the spindle arm which was modified to ‘drop’ the bolt hole down. Rack also has solid offset bushings raising rack up. Added rack extenders to inner tierods.
