I have a set of Front AND Rear Brembo calipers and pads from an '04 STi with pads (NO rotors). They are in great shape with minor scratches from their minor use.
I WILL NOT part the set unless I have a confirmed buyer for the rears as the front are pretty easy to sell.
I think the going rate on fronts and rears is $1200, so that's what I'll ask for them. Shipping and paypal fees are extra, local pickup is fine.
Let me know if you are interested.
Here are the pics, one pic per caliper, but I have more if you need them. These are practically mint, but for two minor "chips" on one front and one rear.
