That's the local forum. Mostly everyone on there is hoonigan drifters, but its good for buying and selling parts.

Everything else, zilvia is good, or import stuff from japan. Yahoo auctions and using the streeter method is good. That can be found HERE. Other than that, there is a couple local garages. Monkeynutz, Shift motorsports, etc
