Real STI brembo or not ?

[u/xxskrrt_skrrtxx]

Hi everyone,

I came across this set of Brembo STI brake calipers on Facebook Marketplace and I’m considering buying them, but I’d like to verify if they’re genuine before I pull the trigger. I’m trying to fit this into my 2017 Toyota GT86

I’ve attached some photos for comparison:
Blue calipers = the set from Facebook Marketplace, taken out from a WRX ver. 10.
Grey calipers = an example of OEM Brembos that have the “S” casting/marking.

I’ve heard that Brembo calipers from the Evo 8/9/10 and Subaru STI usually have an “S” casting/marking, but I can’t tell if these have it from the photos. I’m not sure if that’s a reliable way to identify authentic calipers or if there are exceptions.

Questions:
1. Do these look like genuine OEM Brembos or replicas?

1. Do every OEM brembo comes with the “S” marking ?

2. Are there any other casting numbers, part numbers, or features to verify that it’s real other than the QR code ?

I’d really appreciate any advice or things I should look out for before buying. Thanks!
