I Think you are building your suspension. The kits I saw moved the locations of the rack or pivot points at the steering arms. In the Wiki on using a caviliar in an early GM suspension upgrade the writer moved the location and angles of the rack to fine tune it. Can you lock a brake rotor, have the suspension with out springs and shocks. Fasten a laser pointer to the rotor then move the suspension and rack around and watch the dot. watch camber change, castor change. toe change etc An old Ford buddy, Bruce Cambern, retired head of Ford racing. has done a lot of suspension work on his 66 Cobra, 2009 Optima winner, and some Cad analysis. It just takes longer doing it with the car.
