Option 2NK (M Carbon Ceramic Brake System), originally announced for 07/12 production, has been delayed by BMW AG for F1xM models (M5, M6 Convertible and Coupe) until calendar year 2013. Therefore, option 2NK is being removed from all pipeline orders. Marketing materials and the Ordering & Pricing Guide are being updated accordingly. Please review all M5 and M6 orders to ensure order accuracy, keeping in mind option 2NK required option 2NZ (20" M Forged Wheels), which may remain on the orders.
