Sprint star, I'm not much help with 1302/1303, I've never had one.
Reviewing my suspension books this evening, about the only thing you can do on a strut suspension to decrease scrub radius (if your wheels are as inboard as possible) is tilt the top of the strut inboard to increase the kinpin inclination angle but then you get into excessive camber unless you can modify the spindle to compensate for the angle change and reduce the camber (not easy). The strut design is your limiting factor. If you have too much kingpin inclination, say over 9 degrees, your front suspension will feel "floppy" as you turn the tires. Suspension design is all a compromise and never comes out perfect in all situations.

I think the only useable suspension with "0" scrub radius will be a double wishbone suspension with a small spindle tucked well inside the wheel. Due to the strut on a super I don't think the spindle can be placed far enough inside a wheel to achieve "0" scrub radius due to spring interfearance.

You've got me curious, draw it out and let me know what your results are.

If you don't have a lot of scrub radius, I would not loose any sleep over it, minimize it with wheel offset and get on with other things. I would guess that a stock super would have some built in anyway.
