King Pin Inclination Help?

[URTOAST]

Ok so your asking about Steering Axis Inclination, not KPI as king pins havent been used in cars in decades.
SAI is actually the combination of the incline based off of the theoreticle center of the tire at 0 camber and the centerline through both ball joints or lower andbj and upper bearing plate.
If I understand what was done in the machining was to change the camber SAI has nothing to do with caster.
OK so just what kind of car is it your working on?
and why are you changing parts?
A little more info on the type of car your working on would help.
I am a 20+yr alignment tech so I understande a few things about suspensions.

Lee,

Thanks for your help. The car is a Ford Shogun, witch in it's self will yield you nothing. Thats kinda why I left it out...There were only a hand full or so built. Basically they took a Ford Festiva FWD car and removed the engine, inserted a fuel cell, and placed a SHO drivetrane in the trunk, making it a mid engined RWD car. They were the hot ticket in the 90's and preformed very well for what they were. Some hate them, others like me love them... well some days

What the original builder of the car told me was he removed some of the Inclination of the FWD set up of the car because most FWD cars have a higher inclination rate then there RWD counterparts?

This problem is only on the front of the car... We are using the stock lower control arm, and the stock upper strut location so I'm have no doubt putting this thing together as is would work, but there were several people that worked on this car originally, and I'm sure they did this for a reason. Camber plates were, and still are available for the car, so I'm guessing this machining process had to provide some sort of benifit.... It doesn't look easy, well not as easy as some adjustable plates

So if this is based on the "center line of the tire" my wheel offset will efect this..... So when he used ...say 8-9 Deg. and one set of wheels, and I switch to another set... how do I know what angle to bore the spindles at?

Thanks
