Based on this, it appears that the CR could potentially generate more lift than the BRZ even with all the "downforce" parts. I wonder how a base S2000 would handle on the same sweeper.

The center of pressure can affect that. If that wing is reducing lift at the back, but not the front, the rear will grip better than the front at speed, meaning high speed understeer.
Keep in mind that all aero lift does is change loading on tires at speed. Tires generate grip based on load. So balancing which end of the car sees more or less load from aero affects under/oversteer relative to speed.
