This carbon fiber center diffuser for the BMW F10 M5 is the best option if you are looking for a subtle diffuser while still adding a bit of carbon fiber to the rear of your M5. This center diffuser is unique in that it maintains use of your factory outer diffuser and installs by replacing the OEM middle section. This F10 CF center diffuser is made using 100% dry carbon fiber which produces an item that is ultra-thin, strong and lightweight for the best fitment possible. This product will match other carbon fiber parts on your M5 as well as it features a 2×2 weave pattern. Although this is made using dry carbon fiber, it still retains that clear coated glossy finish. If you are looking for an easy to install carbon fiber diffuser for your M5 then this is just the product you are looking for!
