Adding a bit more dynamic edge to its most potent U.S. Impreza WRX variant, Subaru has created a new STI Special Edition that brings a more aggressively tuned suspension borrowed from the Japanese market STI spec C model and tosses in unique wheels and graphics for good measure. Changes to the baseline STI's underpinnings include a 1.0-millimeter thicker rear stabilizer bar, stiffer rear sub-frame bushings and revised spring calibrations. The front coils are 16 percent stiffer than a standard STI while the rear shocks rated have been upped by 29 percent. The spec C also contributes its lightweight 18-inch/14-spoke alloy wheels finished in a unique charcoal hue. Due to arrive here in early spring, the first 125 of these Limited Edition cars will all be finished in Aspen White. Later in the year, it will be rolled into the regular WRX lineup and be available in all of the standard STI colors.
Like all STI vehicles, this new Limited Edition was created by the go-fast gurus at Subaru Technical International. It retains all of the WRX STI's drivetrain elements -- a 305-horsepower/2.5-liter turbocharged flat-four, six-speed manual transmission and Subaru's multi-mode Driver Controlled Center Differential (DCCD) variation of Subaru's Symmetrical All-Wheel-Drive system in addition to its bigger Brembo brakes, enhanced stability/traction controls and bolder bodywork. In a nod to its even more overt performance persona, the Limited Edition does swap the STI's HID headlamps for halogen alternatives, has manual rather than automatic air conditioning and makes do with a four-speaker/single-disc CD player in place of the normal 10-speaker/six-disc unit. Pricing gets revealed next week when the WRX STI Limited Edition makes it formal debut at the Los Angeles Auto Show. Subaru's display will also feature a new Impreza WRX Limited model that expands on the feature set of the 265-horsepower WRX Premium by adding leather upholstery, a power moonroof and SIRIUS Satellite Radio.
