Carved from billet magnesium, these striking, lightweight wheels contribute to the FR500’s superb 50/50 front-to-rear weight distribution. Measuring 18x9 inches in front and 18x10 in the rear, these prototype wheels provide ample room for the 14-inch (front) and 13-inch (rear) Brembos. Ford Racing is considering production of the wheels in forged aluminum or magnesium. Clamped by four-piston calipers, the massive front rotors are 1.25 inches thick and are vented, crossdrilled, and cooled by ducting from the front fascia. In back, the vented, 1.1-inch rotors are grabbed by Lincoln LS single-piston calipers. All that hardware is still mastered by the stock four-channel Antilock Braking System.
