Here is the Zaero Design Rear Diffuser in a Gloss Black finish. This product is for the M Sport F40 1 Series with a Single Exit outlet.
The Diffuser changes the rear of the car completely with its aggressive styling; it features sharp edges the whole way round with 3 fins directly in the middle and 2 others on the left and right side. This whole package creates a great a sporty design on the rear.
When installing, no extra screws or bumper removal is required. This fits directly in place of your original Diffuser.
