I installed Bilstien shocks and Tein HD springs. All in all it was a great combo and gave a perfect 2 inch drop. I still think it has excessive roll when cornering so I see a rear sway in my future.
Compared to my 99 GT the 2011 is heavier, bigger and lightly sprung. Subaru really went after the Accords and Camry's when they re-did this model. Well, not after I'm done with it.
