Scrub radius impact on handling

[CTX-SLPR]

Howdy,



Since I have the pleasure of redesigning my front suspension on my '64 Riviera, I can design for whatever offset wheel I want. However since I do want to make an effort to maximize the handling and comfort of the suspension, how important is scrub radius? I'm basing most of the design off of the C5/6 Corvette and using the same upright. Is keeping the same 54-56mm offset critical to the handling and/or bearing life?
How much thought about scrub radius actually goes into most people's wheel selection?
How much impact does say moving the kingpin axis 1in inboard make?

Thanks,
