Aston Martins featuring Dunlop Disc Brakes in the rear (using 1 5/8" pistons) may buy our oversized units (italics) increasing the piston size to 1 3/4". This upgrade will not only reduce the cost of brake replacement, but allow the user to realize approximately 10-15% greater force on the brake rotor, decreasing the required brake pedal pressure during braking, and potentially shortening stopping distances.
