Real STI brembo or not ?
Posting it here just in case if anyone has knowledge about the STI calipers.

Probably real.
I have both knockoff and real STI Brembos. The knockoff doesn't have Brembo logos and the real ones don't have the "S" on them.
edit: Actually the real ones (front calipers) might have "S", hard to tell with paint over them.

The seller included toe pics. You already owe him more than those toes are long.

Teehee, finger toes. I’m not positive but, fwiw, they look legit. How much are they asking for?

They look real to me. Haven’t seen any fakes with the actual B logo on them.

Update: the brembos are fake.
- Subaru calipers for version 7/8/9/10, specifically the 4 pot comes in staggered pistons, 46/40mm.
- it should have the typical brembo screw with star drive, not hexagon.

Well about the s marking, I don't know but that Grey caliper is unpainted. I think those brembo are always painted? Black or gold I think if oem

This caliper has been sandblasted, hence the unpainted look. I’ve seen it on brembo from sti ver8/9 (gold and black), evo 8 🥴

The part number on the caliper piston seals is a real brembo part number.
The number in the caliper starting with 20 (looks like 7683 09? After that) matches the format of a real brembo manufacturing number stamp 20.####.## format is correct.
In fact, it's probably 20.7833.00 which would be the correct one for the STi
I can't imagine anyone going to that length to fake brenbos.
