It already exists in
this form. Much like the Legacy and Forester, there is no badged STI being sold but a slew of STI parts are available. The "Subaru STI" will not have Impreza in its name in a couple years. Because of that, I'm starting to doubt there will ever be a BRZ STI but it might happen overseas and cost twice the price of the base model like the TRD GT86 lol.
