If you own a base model S550 Mustang and wish to add the aggressive diffuser fin detailing of the Premium Package models, with an even more race-inspired appearance, Modern Muscle Design has created these new rear diffuser fins specifically designed for the 2015-17 Mustangs equipped with the non-premium rear bumpers.
These eye-catching diffuser fins are a simple way to drastically upgrade the rear profile look of your S550 with its smooth matte black finish and durable, light-weight and impact resistant injection molded acrylonitrile butadiene styrene (ABS) construction.
These MMD Rear Diffuser Fins were designed using the original OEM CAD data from Ford to ensure a perfect fit and they install without any need for messy glue or drilling.
