I don't really understand your question. You won't be too low in the winter because you get tires with a taller sidewall. The overall size shouldn't change (yes, technically it's off by up to +/- 5mm) to a point that your ride height will change. If that's you meant with your question, I hope that answered.
Stock tires on your 08 WRX (from the factory) 205/50-17
on 16's you'd want to add ~25mm to that number for the smaller wheel.
Sidewall= 127.5. 127.5/205=x where x is a %. (=62%)
Yep, math from high school comes back.
So, a 205/60-16 would be close, with a 205/65-16 going just a touch too big.
This might sound crazy, but I'd look into 195/65-16's if I were in your situation. Overall the sidewall would be 126.75mm, which is dang close to the stock diameter. I live in a place where there are enough snowy days with ice pack on the road on lots of streets where I benefit from the tires biting in deeper like soccer cleats. Some climates need tires that are wider, rather than narrower. I know you get some good snow pack out there in MA, so I would do the same. Just make sure you realize you're not on sport performance tires anymore before you go balls out with your driving. That's all I've got.
