    -Uber lightweight wheels with super stick Extreme performance tires
    -Stainless steel brake lines/track-oriented brake pads
    -Driver enhancement mod (take a class, read a book, go to a lecture, watch a video, do a training day at the track, etc)

    i just took my WRX on the track for the first time a few weeks ago, it was completely stock except for i changed out the stock brake fluid for motul 600 racing fluid.

    you question depends on a few things:
    - where are you racing? occasional weekend auto crosser? street style courses? very long, large fast tracks?
    - budget. with a few thousand $$$ i would get coilovers that are much stiffer and lower the car, thicker sway bars frnt and rear with endlinks, all the bushings under the sun, and have a set of really light wheels with racing slicks on them for the track days. also, invest in racing spec brake pads and stainless steel brake lines.

    good luck. its fun and scary.

    Trackdays at NJMP. 2.1 mile road course. My car is for the street but I think tires and brakes will get best gains but where do I start?

    dont even bother with engine mods at this time, for the $$$, they are not going to net you a lot on such a small track. you need to worry about cornering and being able to keep speed thru corners and putting power down out of corners. my best advice is to take your car out (if you have not done it yet) and find out for yourself what shortcomings the vehicle has and what you need.

    considering the 2011 STI is upgraded suspension wise vs the 2010 STI and way different than my stock WRX, i would say start out with thicker sway bars and end links front and rear, and get a pair of HAWK racing brake pads and see how the car feels. then move on from there.

    Tires: high-end summer tire
    Brakes: SS lines / Master Cylinder Brace, track pads (swap them in when you get there, swap regular pads in after your runs), high-temp fluid (bleed when you get to the track)
