If i bothered to read the first post properly.. GG retard.
You can't really have both reliably. Even if you do want to mix them, if you break said car at the track it can put you up shits creek.
Like i said, personally.... I would go an Emo over a WRX any day. Specifically a IX. They are relatively comfortable, the back seats are actually surprisingly comfortable if people need to use them. Good on the road and their reputation speaks for themselves on the track. Just flash the ECU and wind the boost up. Job done. From factory they are a fantastic package.
