I recently got a 2013 wrx within the last couple months. I plan on leaving the engine untouched to avoid pissing off the dealership guys so I can retain my warranty. Does a replacement of suspension or wheels/tires along with exhaust violate that? She's already tinted, with some rain guards fitted for this friggin Florida weather. What wheels should I go with? Is upgrading the suspension really worth it? Isn't it already a nice suspension? What sort of front tag should I mount on her?
