Question: does static camber affect the scrub radius?

It all depends on how you adjust static camber. Most cars do it by moving the inboard upper or lower control arm points. This increases camber and KPI together so theoretically it is the same- BUT now your contact patch is all distorted and its center isn't where it should be. Another thing happens when you increase camber- you change your track width. How much? We would just set our car on some pressure sensitive paper to find the center at different camber settings, but our tires are way different!

Also, when you add camber, you get Camber thrust, which is additional cornering force, even though the car isn't cornering. Sometimes it makes a difference, sometimes it doesn't, again, depending on what tire your using.

What a lot of Race Cars do is have your outboard balljoints mount on a clevis that then attaches to the upright. This allows you to change camber of the tire without changing KPI or messing with toe settings.
