Like Irine Subaru mentioned most of the parts are not orderable through Subaru, However I am always willing to make some phone calls to SOA and sometimes it results in Fuji releasing the parts, most for the performance parts it is very difficult. Fuji and a problem with SOA selling certain Performance parts do to safty and emission laws.
When I do get parts released or order STI parts the cost to us as a dealer many times is the same as if I were to buy them from performance shops, I really do not know where they get them. We run a Pro Rally car and we are always searching for Subaru parts at the best prices and we usually give large discounts for parts that are used on rally car or track cars because as rally and track drivers ourselves we know how expensive things get.
So before you jump down the dealers throats you should see what we have to deal with for getting these performance parts from Fuji.
always happy to spend the time to find numbers and get the parts!
