Its all personal preference. You said that car isn't going to go to alot of shows, but that doesn't mean you dont want it to look nice. On my car, I dont plan on racing it to much. And i dont plan on showing the car. But i want looks more than performance. Not the widebody or any body kit for that matter, but a nice look. If i had a black WRX i would go with the STi wing, a front lip, black out the side markers, some type of black rims (maybe a polished lip ) and some black morrettes. thats just me.
