PP Brembo dilemma
 

So I've been collecting parts for my PP upgrade on my '13 FRS and have everything except for a right rear caliper. Subaru is backordered "indefinitely" though I have an order in their system. It's been 3 months and no ship date. Does anyone have any other suggestions? Do these cross reference with STI calipers that I can try to find used and remanufacture?

Thanks, kinda stuck.

Nevermind, found the last one in the US and nabbed it. Thanks to a really friendly Subie parts dude.
