Extreme Online Store's complete 2015-23 Ford Mustang S550 (6th generation) catalog — exterior aero, carbon fiber interior trim, steering wheels, exhaust, lighting and accessories, designed and test-fitted on the Mustang S550. Engines across the range: the 2.3L EcoBoost, the 5.0L Coyote GT, the Mach 1, the flat-plane Shelby GT350 and the supercharged Shelby GT500.
The 2018 refresh changed the front fascia, hood, headlights and tail lights, so anything that mounts to those areas is sold as 2015-17 or 2018-23. Rockers, decklid, doors and the interior carried over, so skirts, spoilers, steering wheels and trim fit all nine model years. Use the Model row on the left to shop by trim, or the Category row to go straight to a part type.
Shop by category: Exhaust Systems, Exterior Trim, Steering Wheels, Interior Trim, Rear Spoilers & Wings, Bumper Conversion Kits, Hoods & Hood Vents, Fenders & Fender Vents, Lights & Lenses.
Materials run carbon fiber, dry carbon fiber, ABS plastic and T304 stainless for exhaust. Every carbon fiber part is UV clear-coated for outdoor use; ABS and polypropylene parts ship primed or finished as listed.
Frequently asked
Do you ship free? Yes — free shipping to the 48 contiguous states on every Mustang S550 part.
Are these direct fit? Every part here is designed on the actual car and confirmed for fitment. Installation notes and hardware requirements are on each product page.
Carbon fiber or ABS? Carbon fiber is lighter and stiffer with a visible weave under clear coat. ABS is more impact-tolerant and usually ships primed or gloss black — a good choice for splitters that may see driveway contact.
