Steering axis inclination, included angle??

[guitarfreak235]

This is very technical so here goes nothing.

I am trying to calculate what camber my wheels are at at a given toe (steering angle the wheels at) to assess whether i want more caster or not on my 88 gt. (I'm a Mechanical Engineering student so I love to get technical with things)

I have the equation to calculate it just dont know what the fieros steering axis inclination is supposed to be? its supposed to be (included angle - camber) where included angle is the angle between the steeting axis and the hub face (plane of rotation of wheels).

Its as follows:

Sin(C)=(Cos(Co)-Cos(C)Cos(T))Tan(S)-Cos(C)Sin(T)Tan(K)+Sin(Co)

IA=S+Co

Where

C=Camber
Co=Camber at 0 toe. (straight ahead)
k= caster
S=STEERING AXIS INCLINATION
T=Toe (Relative to straight ahead)
IA=INCLUDED ANGLE

All I need is steering axis inclination or Included angle. Included angle is literally just the angle between the steering axis and the hub face.

...anyone?

The only person I know, who would probably be able to pull that figure out of his... back pocket, would be Fieroguru on Pennocks.
There may be one or two others, but if he doesn't know it, he would know how to measure it.

Or Rrunner.

When I was employed building hot rods, we always set the caster about 7 degrees, for what its worth.
