Subaru makes no mention of any other S209 weight loss, but the looks and the "focus on high-performance driving" should make themselves known. STI widened the front and rear track by 0.6 inches, and punched out fenders with aero-aiding canards make the car 1.7 inches wider. The roof and rear wing are made of carbon fiber. Instead of the 245/35 R19 wheels on the series WRX STI, the S209's forged BBS alloys wear 265/35 Dunlop GT600A summer tires, which we're told can handle max lateral grip beyond 1 G. Behind those wheels, six-piston monoblock Brembo calipers with high-friction pads clamp cross-drilled steel rotors in front, two-piston monoblock calipers in back.
Stiffer coil springs wrap retuned Bilstein dampers, the suspension aided in its work by reinforced front crossmember and rear subframe, a longitudinally-flexible strut tower bar in front, flexible draw stiffeners front and back, and a 20-millimeter rear stabilizer bar.
STI programmers recalibrated the SI-Drive system's three driving modes: Intelligent, Sport, and Sport Sharp. Notably, they recommend Sport for track work, since "the less aggressive throttle map allows for greater driver control." Sport Sharp is for acceleration runs.
The cockpit doesn't change much save for Ultrasuede on the steering wheel, silver inserts for the Recaro buckets, silver stitching throughout, plus plenty of S209 badging.
Subaru says it will make "around 200 units," all for the U.S. The two color schemes will be World Rally Blue Pearl with gray wheels, and Crystal White Pearl with gold wheels. We'll get pricing closer to when the order books open in late 2019.
