The only "proof" I have seen for the BRZ spoiler came from the JDM versions which also have the under body panels, and the net effect for both combined was going from 0.29 to 0.27...
I have never seen any proof of the BRZ spoiler having positive effects in isolation (e.g. without other supporting modifications). Our US FRS cars do not have the same underbody panels (part of the cost reduction by Scion).
In any event the total effect of the pre facelift spoilers (BRZ and FRS) even with underbody panels is almost meaningless for practical purposes.
The tS wing, with proper adjustment, might be interesting on a track... but is a bit too much for my tastes as a daily driver.
Good luck - I doubt you will find much hard evidence on the FRS spoiler.
