i kind of get it but im using more castor on threaded castor rods (not using the full threaded part currently).

also fine tuned with s13 cambet ops asdid piggy and boof by installing on a diagonal angle. reduces neg camber slightly on mine but castor did make car feel more stable bt with slightly increased steering effort (no drama in a 1200 and i thought gave more feel through the wheel too for input into a corner)

Dont worry about the gas stuff, just look at the angle of the camber top gives castor and camber adjustment this way
