I think we're getting at the same concepts. Trail has to be tailored based on rolling radius of the tire, and static camber adjusted based on the tire contact patch and subsequent dynamic camber at a specific g-loading.

e.g. running a smaller tire radius increases trail for a given caster, so to maintain the same trail, less caster is needed. That matches the Caddy tuning as they run smaller tires.

The outlier is the Camaro FEA setup, which runs a 26.3" diameter front tire (smallest of all the Camaro's but on par with the CTS-V) and the same caster as the FE4 Camaro. This likely results in the most trail of the group, and that's appropriate for a track car.
