Newbie question, where to buy BRZ Performance Package and TS parts?
 

Do dealers sell them individually? I’m looking for BBK, wheels and exhaust from those two Subaru factory packages.

Exhaust is the same. Yes, dealers will sell everything separately. Bought individually, you're going to spend a TON of money and are probably better off looking aftermarket, or selling your current car and purchasing a PP. The brakes alone are several thousand dollars for calipers, rotors, and pads.
