I also had an STi- a 2004 WRC Blue with gold wheels. Bought it brand new and loved it for 150k miles. I’m also a former 911 owner, and owned the last gen to have hydraulic steering. I can tell you that the weight balance of the Emira (and Evora) is closer to a 911 than to a Boxster/Cayman. That said, the difference between an AWD front axel vs a lightly loaded and un-powered front axel is fairly large. The STi would wriggle not only from the loading of the tires and shifting of weight from front to rear, but mostly from the power being fed through to the front wheels (and left to right- 3 differentials). The 911, by comparison, was unburdened by power delivery to the front wheels, and the weight of a front engine, so the steering felt so much more delicate. I’d imagine you’ll love the feeling!
