I've got a full set of Girling E30 brake calipers from an 86 325es, in perfect condition. They of course just need to be cleaned up a little, but they're in great shape. Pics availabe upon request. I'd like to get $100 for the complete set, or $50 for the front and rear sets separately. I'm not going to split the 2 sets apart, unless you can find another person that's willing to buy just the one side opposite of the one you want.
