2015-2017 vs. 2018+: Why Front End Parts Don't Swap on the S550 Mustang
Share
You own a pristine 2016 Mustang GT. You love the car, but you absolutely crave the sleek, aggressive front end of the newer 2018+ models or the legendary GT500.
You find a premium 2019-spec carbon fiber hood from Anderson Composites online. You buy it. You unbox it. And then you try to test-fit it.
It doesn't line up. The gaps are massive. The headlights are in the way.
Welcome to the S550 Facelift Split.
In 2018, Ford executed a major mid-cycle refresh that changed almost every single panel on the front of the car.
- 2015–2017: Taller headlights, a higher, flatter hood line, and a blunt nose.
- 2018–2023: A "droopy" aggressive nose, a lower hood, and sharply angled headlights.
If you want to upgrade your front aero, you cannot mix and match OEM-style parts across these two eras. In this guide, we explain the "Facelift Split" in detail, helping you navigate the premium catalog of Roush, APR Performance, and Ford Performance to ensure you order the exact right splitter, grille, or carbon fiber hood for your specific model year.

Frequently Asked Questions (Exterior Upgrades)
Will a 2018+ front bumper or hood fit my 2015 Mustang?
Not directly.
Because of the 2018 "Facelift," the headlights, hood, and fenders are shaped entirely differently. To put a genuine 2018+ style bumper or hood on a 2015–2017 car, you would have to swap the headlights and fenders as well. Always filter by your exact year when buying front-end aero.
Do I have to drill holes in my trunk for a GT350/GT500 spoiler?
It depends on how your car left the factory.
- If you have a factory lip spoiler: Premium upgrades like the Ford Performance GT350 Track Spoiler usually reuse the exact same holes left behind when you remove the factory lip.
- If you have a Base model (No spoiler): Yes, you will need to drill holes in your pristine trunk lid. Premium kits include exact-measure templates to ensure you drill in the correct spots.
Are carbon fiber hoods street-legal and safe?
Yes, but hood pins are highly recommended.
Brands like Anderson Composites manufacture incredible, show-quality carbon fiber parts. However, because carbon fiber hoods are drastically lighter than the factory aluminum/steel hoods, the factory hood latch alone is often not enough to secure it at highway speeds. Installing a high-quality set of hood pins is heavily recommended to prevent the hood from flying up while driving.
