1: I’m interested in doing some light performance modding but I also want to baby this car and keep it as long as possible, what performance mods impact the longevity of the car the least? (While also complying with CO emissions regulations)
2: is there any STI specific maintenance I should be aware of?
3: Generally is there anything you wish you knew sooner about owning a wrx?
4: what kind of cosmetic mods do you think would look cool on my car? I wanna keep it subtle and I don’t like the carbon fiber look.

I’m sure I sound clueless but that’s why I’m here so please be nice lol
