BMW 330i brake calipers that come with sensors, discs, pads. The pads and discs have been used to get out in the street and test the car before the engine hydrolocked itself. There are marks on the discs, as the brakes have been used whilst testing, see pictures. This is due to the weight and to seperate discs from calipers. I would prefer if you collect in person, but will send if that is a better option for you.
