I know the motor well as I
I know the motor well as I had it in my 2012 sti .Evo boost comes on sooner and the clutch is much more user friendly but I will take an Sti for those long hauls any day cant comment on the 2015 never owned one but I love my evo in the corners .Calling it a one trick pony describes it pretty good .I would not want to drive it every day .
