"Personally depending on your budget I'd start (if I had to do it all over again):
-Eibach lowering springs
-CAI (either needswings or anything from TVT)
-KYB or Koni shocks (you may want to do this at the same time as your springs to save trouble)
-Then save up for an engine tune with larger injectors"

Where can you get all this stuff from?? Mostly interested in the injectors and CAI.

Thanks
