Reinforceable bushings can be identified by sight, they have holes in them. Those holes, made for compliance, allows unwanted drivetrain movements as a consequence. My curiosity is simply... are the BRZ's diff bushings the same as OEM on other Subaru's, or a better one specific, part number-wise, to the BRZ. There's where details in a service/parts manual come in.
The FR-S would have those in Toyota part number format, so you'd have to wait until the BRZ manual is available.
