hey all! I have a dilemma and need your input. I have a 2003 WRX stock, 5 speed standard. I'm happy with it but i want to get some more out of it. The thing I'm worried abt is that I drive 70m everyday. (im actually thinking of doing seletive things from this list of stage 1 recommendations **Complete WRX Tuning Guide**) Does going to stage 1 change anything given my driving miles and does the maintenance go up? I don't want it to be a financial kill. I'd also love someone here help me do the install. Thanks so much guys.
