I've owned my 11 Wrx sedan for about 3months (4200 miles) and have dumped a lot ( more than expected for this soon) money into getting my power out of the car. I'm currently stage 2, on e85, and very content with it. My question is, should I be changing/upgrading and of the fluids in the car, besides the oil? I don't drive like a Dbag, so it rarely sees a lot of boost for any length of time, but with the car only having 26k miles, I'd like to keep things running as smooth as possible. Any input or recommendations are very welcome.
