Short shifter - Kartboy is popular http://www.kartboy.com
Don't forget the Cusco shifter bushings.
18mm or 20mm rear sway bar to adjust the handling from understeer to neutral or throttle on oversteer.
Suspension - choose your weapon here...
- Rallispec fast road set up http://www.rallispec.com
- Prodrive P1 (that kit will eat up most of your $$$) http://www.spdusa.com
- KYB AGX struts/springs of your choice
I'm installing these struts with Eibach SPD springs next week. Adjustable dampening on these struts. Search around for the best deal.
Ganz CAI (Cold Air Intake)
Rear strut tower bar - Front doesn't make that much difference.
New tires - Kuhmo 712's seem popular and cheap. (My springtime purchase)
Exhaust backbox - our cars don't gain from a full catback system. Popular choices are Stromung, Scoobysport, STi.
Hope this helps...
