    Description

    Pre-Painted MMD by FOOSE Rear Diffuser Fins

    Track Styling by FOOSE. Add bold track inspired styling to your S550 Mustang with a set of MMD by FOOSE Rear Diffuser Fins. Designed by renowned custom car builder Chip Foose, these Rear Diffuser Fins will add an intimidating appearance to the rear of your 2018-2023 GT Mustang. These Rear Diffuser Fins are also available pre-painted in 2018-2023 factory colors.

    High Quality Construction. MMD by FOOSE manufactures their Rear Diffuser Fins from an acrylonitrile butadiene styrene (ABS) material using the original OEM CAD data from Ford to ensure a perfect fit. ABS is an extremely strong material known for its light-weight, superior durability and impact resistance - making it perfect to withstand the hazards of daily driving.

    Simple Installation. MMD by FOOSE designed their Rear Diffuser Fins to install simply with the supplied push clips and 3M doubled sided automotive bonding tape. Drilling four 1/4-inch holes into your Mustang's rear lower bumper cover is required for installation. Installation can be completed in less than 30 minutes.

    Application. These Unpainted MMD by FOOSE Rear Diffuser Fins are designed to fit 2018-2023 GT and EcoBoost Mustang models with quad exhaust and the factory rear diffuser installed. Driver and passenger side Fins are included.

    Technical Notes. These MMD by FOOSE Rear Diffuser Fins ship unpainted. AmericanMuscle recommends professional installation of all body parts. We also recommend test fitting these products before they are painted.
