anyone know if sti brembos are a direct bolt on to an 02-05 wrx hub? obviously i'd need the sti rotors as well but just wondering about the calipers.
Front calipers might, but I think the rears require some effort. Might want to let someone else chime in on this one though.
Fronts bolt on. For the rears, you need a bracket if you don't want a whole STi rear end. Mike Wray found or had made a bracket that makes the rears work on non-STi knuckles.
For the rears, barring a custom piece, you need to change the entire backing plate. That involves pressing the hub out of the bearing. When you do that, Subaru recommends replacing the bearing. I have done it without replacing the bearing on my rally car but I would not recommend doing so on a street car. I went through bearings and knuckles quick enough they didn't have time to fail due to the extra press work I put them through. Mark Utecht
