I found brand new brembo brake calipers for 350. Here's my problem. I don't know what they are even for Subaru or what ever. They are gold so I assume for a Subaru. And say brembo in red. No numbers on them. How do I know if they will work on my 2011 wrx? Bolt size and thread pitch? How far the bolts are apart? Idk what I need to look for. Any help is really helpful
