What size brakes does the 850CSi have?
There are two different braking systems for the 850CSi. European-spec cars are equipped with the same braking system that was fitted to the E34 M5 starting with May, 1994 production. This consists of 13.6-inch vented discs incorporating “floating” rotors and four-piston calipers in the front and 12.8-inch vented discs in the rear. U.S.-spec cars are fitted with the same brakes as the standard five-liter 850i/850Ci: 12.8-inch vented discs in the front and 12.8-inch solid discs in the rear.
