upgrade poll

[army_mechanic]

Im taking a poll on what to upgrade next on my mp3 currently I have an injen intake, catback exhaust. I also have a B&M short shifter and Eibach lowering springs 1.5" drop. I will be boosting down the road so I dont want to waste money on a header. Ill more then likely be getting all the upgrades on the poll just curious to see what you guys think on the most effective one so i can get it next. Thanks for the input.

What about tires? Tires are hands down the best upgrade for any car. From the list though, I guess clutch and flywheel. No sense only doing one since you'll already be in there.
