Rear Diffusers for the 2024-Up Ford Mustang S650 (7th generation): finned rear diffusers, diffuser fin extensions and full bumper-integrated diffusers in carbon fiber and ABS. The diffuser finishes the rear view and pairs with your exhaust tips and spoiler. Everything on this page is confirmed for Mustang S650 fitment.
EcoBoost, GT and Dark Horse share the same body shell. Front fascias differ — GT and Dark Horse run the larger lower grille and the Performance Pack splitter, and the Dark Horse has its own rear wing — so bumper-mounted and wing parts are trim-specific while trim, interior, hood and exhaust parts fit across the range. This page covers EcoBoost, GT and Dark Horse; use the Model filter on the left to see only parts for your trim.
Materials run carbon fiber, dry carbon fiber and polypropylene. Carbon fiber parts are UV clear-coated; ABS and polypropylene parts ship primed or finished as listed.
