Description
Carbon fiber rear bumper diffuser for the 2015-2017 Ford Mustang.
It fills the lower rear bumper with vertical fins. From behind, the diffuser is what makes the back of a Mustang look finished rather than empty.
Fits EcoBoost and GT models, 2015-2017.
Hard carbon fiber, moulded rather than wrapped, under a UV-stable clear coat. It holds gloss through sun, rain and road salt without going cloudy at the edges.
Install reuses the factory mounting points. Remove the original screws and clean the surface. Apply the tape, align the part, then refit the screws through the existing holes. No drilling. 3M automotive tape and mounting screws ship in the box.
Available in Standard Carbon, Forge Fiber and Honeycomb.
