All it does is make some hype for the expansion of STI business in the Unites States. They say the in-house tuning firm will in the near future offer upgrade parts for the BRZ’s suspension, brakes, engine, aerodynamic and chassis, but they refuse to get into details.

The NYIAS Subaru BRZ STI Performance Concept features a very well-designed aero kit with sport bumpers, wings and sills, plus subtle STI detailing, carbon aero kit, larger wheels, sport lowered suspension, and, apparently, an engine from Subaru BRZ Super GT race car.
