rear subaru 2-pot (Black)
I just brought the used rear subaru 2-pot caliper (Black) for my 02 wrx, but I can't find the bracket to fit on the caliper and I don't know which rotor should fit this caliper, does anyone know the parts no. or where can I buy it??

OK where to start.
Your 02 WRX comes equipped with a single pot rear caliper squeezing a 266x10(170)mm rotor. The 170 in parentheses is the diameter of the internal drum for the parking/handbrake.
1. The single pot caliper uses/has 5.75" mounting bolt spacing and bolts to your current rear backing plate which has holes at that distance. The STi 2pot caliper uses 4.5" mounting bolt spacing and requires that you either install the appropriate backing plates in place of the ones on your car or purchase an adapter to go between the 2pot caliper and your single pot backing plate.
The backing plates you need are from the JDM model Impreza NB-R which comes stock with the 2pot rears. The PNs are as follows:
26704FE080 right rear backing plate
26704FE090 left rear backing plate
The installation of the backing plate requires pressing out of the hub, installation of the plates, and pressing the hubs back in. Big job requiring a machinist's press.
The adapter I spoke of is only available in Japan and costs about $350/pair.
2. The rotor you need for use with the 2pots on your R160 rear assembly equipped WRX is also from the NB-R. Its a 290x18(170)mm rotor and the PN is:
26700AE030 (x2)
HTH
Your purchase of the calipers netted you about a third of the parts needed to complete the job on your car. Thats why the rear 2pot upgrade is more expensive than the front 4pots.
