Well I am getting closer to what I think I need. Reading Ron Suttons Sticky thread on front suspensions has been a great help. I had to move it too rear steer to get the ackerman angle where it should be. I would have preferred front steer but the steering tie rods would hit the rotor or the other option was to move it towards the rear but still in front of the wheel centerline. But with manual steering it would increase the force required to turn the wheels. Moved to rear steer and all is good. A lot of great cars had a rear steer set up with the rack positioned high above your feet. The Porsche 956/962 was manual steering with rear steer and it still holds the fastest lap at the Nurburgring.
Here is what I have for numbers now with
1" dive 1 degree roll with wheels a 21.1 degree's outside 25.1 degrees inside
-4.28 camber outside tire 3.61 degrees inside tire
66% ackerman
25.5% antidive
4.49" roll center
Now I just need to put the numbers into CAD and make sure there are no rim to control arm issue's. If no problem there I will model the uprights and machine them and see how it goes.
Opinions appreciated.
