I have a couple sets of brand new/unused genuine Brembo front brake pads for sale. These will fit all MY04-08 Brembo calipers and MY09-12 STI calipers. These pads comes with the red Brembo backing plates and are directly from Brembo themselves, not Subaru.. other than that.. it's identical to the ones you would buy from Subaru Parts Dept. (since Brembo makes it for Subaru anyways). Pad material are ceramic/semi-metallic.
Subaru list these for around $250 (P/N: 26296FE100) but I'm willing to let it go for $100 shipped via USPS Priority Flat Rate anywhere in the US (That's $150 off what dealer charges). Pick up are available & preferred as well if you're a local.
