Am I right in saying these pads ONLY come standard on 08+ STIs? If so, take it to one of the two STI authorised dealers in Perth, Subaru Ossy Park, or City Subaru. They should know what they're doing. Might still charge you I guess, but I'd also guess they'd get to the bottom of it quicker?

Edit: Sorry just read your post properly, you're going to City Subaru already...
