I traded in my 2000 Silverado for a 06 subaru WRX... New 2.5L turbo engine, bigger brakes, aluminium suspension bits, better tranny, and a few other things made the 06 a huge upgrade over the 05 wrx....
Current mods (car still has temp plates):
-whiteline adj 27mm front sway bar
-whiteline adj 24mm rear sway bar w/ kartboy endlinks
-h-brace (under car in front, keeps the lower control arms from moving around under load)
-rally armor mud flaps
-gauges (boost, EGT, oil pressure)
-meth injection (being installed currently)
-intercooler sprayer (external mist over intercooler, cools intercooler, also being installed currently)
On order:
Racecomp engineering kool brake kit (brake ducts for brake cooling)
KW variant 3 coilovers (2 way adjustable coilovers)
camber plates for the front, harded top hats for the rear
Future plans:
Engine management (will order this when I finish installing the meth injection)
turbo back exhust
big brake kit for front
