New for the STI(s) this year is an improved suspension consisting of stiffer bushings, stiffer springs, and thicker anti-roll bars at both ends of the car. The 2011 STI also sports less unsprung weight than the 2010 model due to lighter 18-inch wheels that are a combined 17.6 pounds less heavy. While power is unchanged (305 horsepower and 290 pound-feet of torque), high-speed stability of the four door is greatly improved, as is at the limit handling, by you guessed it that mega wing.
