Going to be using different calipers so these are up for grabs. They're in very good condition and come with pads which have a decent amount of life left. There's no damage and they were working without any issue prior to removal. They will need a bit of clean though. These can be used on all 848, 1098 and 1198. Good upgrade compared with the standard brakes on the 848. A check online shows most of the M4s going for over £300 but I'm looking for £285 Including postage.
TO the buyer, when installing, I'd recommend using a cloth between calipers and wheel rims to prevent marking as IMHO they are quite a close fit.
