Hi Rico. A lot of variables here, but I'll share with you how my NAF is set up.
1) Floor to frame: I'm going to assume you are asking about ground clearance - "Ground to frame".
Now the variables: my car has a highly modified Mustang II front suspension and a Ford 9" solid axle rear end with adjustable coil over shocks front and rear.
I set my ground clearance so the tires look "right" in the wheel well openings and I don't have bottoming out problems.
So I have 4 inches ground clearance in front to the bottom of my
oil pan and 4 1/2 inches ground clearance in the rear to the bottom of the main frame rails in front of the rear axle.
2) & 3) Camber and toe in are somewhat dependent on what front suspension you have. Mine is set at a rather generic 1 deg of negative camber and 1/6 inch toe in.
Others may have better advice.
Chers
Greg
