You mean the JDM car right? One of the things they cut from the FRS was those belly pans.
Eg:
Aerodynamics discussion - Scion FR-S Forum | Subaru BRZ Forum | Toyota 86 GT 86 Forum | AS1 Forum - FT86CLUB
I'm not 100% sure on the BRZ Premium or Limited. It's been a few months since I've seen the pictures.
The tires are actually from the Performance package for the Prius, (not available in the US). So even though they are a bit wide, they are LRR. Which is good enough for me.
