29 more hp, close to same weight(got a quote of 3265lbs from dealer in amarillo), six speed transmission(final drive same as the wrx).0-60 it lost,1/4mile lost,braking lostpretty sure it lost handling too. something seems funny. Also they said the tunable diff was to go from factory 35f 65r to a max of 50f 50r why would you want to GO to 50/50. My wrx now has a nasty nose push(especially in the dirt and gravel) nothing will respond faster than the computer anyhow. I would have thought it would have been the other way so you could flick and retrieve the rear end like an M3.
