what are your goals? Are you looking for your car to be more aesthetically pleasing? Are you looking to make your car capable of track days? Are you looking to improve the sporting capabilities, but still allow it to be able to have enough suspension travel to soak bumps?
For aesthetics, I would get a nice set of 18" wheels with 40 or 45 series tires, and swift springs.
For a daily driver capable of doing track days/autox, I would suggest keeping stock size wheels or smaller, using springs struts intended for an STI (oem or aftermarket).
For a sportier feel near stock ride height, I would suggest stock wheels with swift springs.
Be the man that your dog thinks that you are.
