First things first, just got my 2012 WRX and have had it for about a month now..... yay!
Now on to the actual question...
As far as performance mods, which brands does everyone here prefer?
I'm looking to try and stay with one brand as much as possible but not a necessity. Been looking as going with the Perrin route preferably but if there junk then I guess not. Any help would be great guys!
