This is a brand-new OEM Subaru Brembo caliper, just like what comes on the 2018 WRX STI. Sold individually; choose left or right. This is loaded rear caliper, pre-assembled with factory pads and hardware.

Caliper note: These calipers are very large and very heavy. Although Subaru packages them in protective paper and bubble wrap, they do get dinged and scuffed up a little in shipping, just from their own weight rubbing against the packaging. Small cosmetic flaws in the finish (as shown in the photo with the finger) are normal and we will NOT accept returns based on cosmetic issues with the caliper finish. The calipers are scarce and hard to source, so we do not get to pick and choose which ones we get.

Fits all 2018 Subaru WRX STI. Could be retrofitted to other Subarus, but you'd need rotors -- we offer a kit .
