RobFrey,
For a car like you are planning I would be very cautious about using something like the Anglia spindle for the front. I agree with Tony you should make the setup zero offset steering and you probably need to do some looking at what the front wheel loads will be. I would think that you will probably have your water tanks forward of the motor and probably other parts plus your body will probably generate some down force and I would bet that if you looked at the bearing load capacity of the Anglia spindles at 7000 rpm + (that is 450 mph with a 21 inch dia tire) it would be marginal at best. For the kind of effort you are planning, spindles specifically designed for your car with carefully selected bearings that will carry the load at the speed you are contemplating are a must.
