The Impreza WRX STI received some updates for 2011, and the biggest one is the return of the four-door sedan. The five-door STI is still available, but buyers now have a choice--the first time American STI shoppers have had that opportunity, in fact.
The 2011 STI also received some stiffer springs, thicker anti-roll bars and a lowered ride height. Want more details? We reviewed this one soon after its release.
