We have an 03 with the power /mods equivalent of a Cobb Stage 2. Rides on Prodrive springs/KYB AGX with a handful of other suspension/brake performance mods. We are not even remotely considering a newer one. I'm just curious, what do the newer WRX's (model years 12-16 and 17-20) do specifically better for the average driver? Not talking about STI's.
