With 305 hp already on tap from the STI’s turbocharged flat-four, there wasn’t much need for more power, so Subaru’s engineers focused on what needed help the most: the suspension and on-road handling. The upgrades made to create the 2010 STI Special Edition were only the beginning; the ’11 STI goes further with an even more aggressive suspension to reduce body roll and create more neutral handling. Compared with last year’s STI, the ride has been lowered and both the front and rear anti-roll bars have been beefed-up in diameter by 1 mm. Stiffer springs—to the tune of 15.6 percent in the front and 53 percent in the rear—are installed, as are more rigid rear subframe bushings and new pillow-ball bushings in the front. Subaru says that extensive testing on the Nürburgring resulted in crisper handling while maintaining a livable ride.
