FHI Subaru 2-pot rear brakes (NOT BREMBOS). Use 290mm vented rotors (not included) and they have nearly new pads of unknown make, but I do know they are the street version. They are in good shape with few scratches except on the "u" as you can see in the picture. These have ~10k miles on them. $340 shipped
FYI, these do NOT work with stock WRX rear rotors and you will need to purchase adapter brackets for the calipers. Lowballers will be scoffed at
