The best carbon fiber body parts for the 2018-2019 Ford Mustang are the Anderson Composites Type-JTP widebody fender flares, a 10-piece prepreg set that transforms the S550's stance while shedding weight over stamped-steel and plastic panels. Carbon fiber body parts are lightweight exterior components — hoods, fender flares, front splitters, rear diffusers and grilles — molded from woven carbon and epoxy resin to replace heavier factory panels on the 2018-2022 Mustang. In our Tampa, FL shop we build S550 street and show cars weekly, and Anderson Composites is the line we reach for when a customer wants real dry-carbon quality that bolts to factory mounting points. Below are the six pieces we install most on the facelifted 2018+ Mustang GT, EcoBoost, and Shelby, with real prices, construction details, and fitment notes.
Our Verdict
The Anderson Composites Type-JTP Fender Flare set is the biggest-impact carbon fiber upgrade for the 2018-2019 Mustang.
If you want a single upgrade that changes how the S550 looks and lets you run wider, more aggressive wheels, the 10-piece widebody flare kit is it. Pair it with a double-sided carbon hood and a front chin splitter for a complete, cohesive build. Every part here is genuine prepreg carbon that fits the 2018-2022 body.
Shop Our Top Pick →Why Carbon Fiber Body Parts for the S550 Mustang?
Carbon fiber cuts weight where it hurts most on a Mustang: high and over the front axle. A woven-carbon hood typically weighs 30-50% less than the factory panel, and pulling 10-15 lbs off the nose sharpens turn-in and reduces front-end pitch under braking. The 2018 model year brought the S550 mid-cycle refresh — a reprofiled hood, new front fascia, and the Gen 3 Coyote 5.0L V8 rated at 460 hp and 420 lb-ft in the GT, alongside the 310 hp 2.3L EcoBoost and the 526 hp 5.2L flat-plane Voodoo in the GT350. That facelift is why 2018-2022 body panels do not interchange with 2015-2017 parts, and why fitment matters.
Beyond weight, carbon fiber body parts deliver two things factory panels cannot: exposed 2x2 twill-weave visuals that photograph beautifully in the sun, and functional aerodynamics. A front chin splitter and a rear diffuser add downforce and manage airflow at highway speed, while a widebody flare kit lets you fit a wider wheel-and-tire package for more mechanical grip. For a street car, the look drives the purchase; for a track or autocross build, the aero and weight are the payoff.
The 10-piece Type-JTP widebody flare set clears wider wheels on the 2018-2019 Mustang.
How We Chose These Carbon Fiber Parts
Every part on this list is genuine Anderson Composites, molded from aerospace-grade prepreg carbon fiber with a 2x2 twill weave and a UV-resistant clear coat. Prepreg (pre-impregnated) carbon uses a controlled resin-to-fiber ratio and is autoclave-cured, which yields a stronger, lighter, more consistent panel than cheap wet-layup carbon. Where a part is offered in Double Sided (DS) construction, it carries finished, show-quality carbon on both the exterior and the underside — no raw fiberglass backing showing when the hood is up. We only included pieces that we have verified fit the 2018-2019 S550 body, and each links to its live product page so you can confirm your exact trim.

1. Anderson Composites Type-JTP Widebody Fender Flares (Top Pick)
This 10-piece Type-JTP flare set is the single most transformative carbon fiber body upgrade for the 2018-2019 Mustang. It widens all four corners so you can run wider, more aggressive wheel-and-tire combinations that fill the arches, and it does it in genuine prepreg carbon rather than painted plastic. The kit mounts to factory reference points and covers 2018 through 2022 GT, EcoBoost, Bullitt, and Shelby GT350/GT500 bodies. At $4,499.10 (down from $4,999.00), it is a serious build centerpiece, not a bolt-on accent.
Key Specifications
What We Like
- + Complete 10-piece set covers all four fenders for a finished widebody look
- + Genuine prepreg carbon, not painted ABS plastic
- + Clears wider, more aggressive wheel and tire packages
Things to Consider
- – Professional install and fitment work is strongly recommended
- – Special-order item; not an overnight shelf part
2. Carbon Fiber Hoods: Ram Air vs Type-OE
A carbon fiber hood is the highest-value single upgrade after the flares, because it removes the most weight from the highest point on the car. Anderson Composites offers two standout options for the 2018-2019 Mustang: the aggressive Ram Air Double-Sided hood at $2,069.10, and the sleeper Type-OE Double-Sided hood at $1,979.10. Both use Double-Sided construction, so the underside shows finished carbon, not fiberglass — a detail that matters at every car meet where hoods go up.
Functional ram-air venting pulls heat out of the Coyote engine bay.
Which hood is right for you? Choose the Ram Air hood if you want visible aggression and functional heat extraction over the Coyote or EcoBoost engine bay. Choose the Type-OE hood if you want the weight savings and carbon look while keeping the factory silhouette — it is the sleeper choice that pairs cleanly with the widebody flares without shouting.
3. Front Aero: Type-AR Chin Splitter & Type-GT Grille
The front end is where the S550 shows its face, and two carbon pieces sharpen it. The Type-AR Carbon Fiber Front Chin Splitter ($1,169.10) extends the lower fascia forward for genuine downforce and a planted, race-inspired stance. The Type-GT Carbon Fiber Upper Grille ($809.10) swaps the plastic upper grille surround for woven carbon, tying the front end into the rest of the build for the lowest price of any part here.
4. Rear Aero: Type-OE Quad-Tip Carbon Diffuser
The Type-OE Carbon Fiber Quad-Tip Rear Diffuser ($1,079.10) finishes the build at the back. It is shaped to frame the GT's factory quad-exhaust tips, cleaning up airflow exiting under the car while adding an OEM-plus carbon look that matches the front splitter and hood. It fits the 2018-2019 Mustang GT and EcoBoost, and it is the natural rear counterpart to the Type-AR front splitter for a balanced, finished aero package.

Installation & Fitment Notes for the 2018-2019 Mustang
Carbon fiber body parts are a professional-install upgrade, and correct fitment is everything. Because 2018 was the S550 facelift, these parts are cut for the 2018-2022 front and rear body and will not fit a 2015-2017 car — always confirm your exact year and trim before ordering. Carbon hoods mount to the factory hinges but generally require aftermarket hood pins or a latch kit to secure the lighter panel safely at speed. Splitters and diffusers bolt to the lower fascia, and the widebody flare set is a bond-and-bolt install that benefits from professional test-fitting and paint or clear-coat blending. Anderson Composites parts arrive gel-coated with a UV clear coat and are backed by the manufacturer's warranty against defects. These carbon pieces are special-order, made-to-order items rather than shelf stock, so build lead time into your project timeline. Our Tampa, FL install bay handles fitment, hood-pin setup, and paint blending on S550 builds regularly — reach out if you want it done right the first time.
Frequently Asked Questions
What are the best carbon fiber body parts for a 2018-2019 Mustang?
The best carbon fiber body parts for the 2018-2019 Mustang are the Anderson Composites Type-JTP widebody fender flares ($4,499.10), a Ram Air or Type-OE double-sided carbon hood ($1,979.10-$2,069.10), the Type-AR front chin splitter ($1,169.10), and the Type-OE quad-tip rear diffuser ($1,079.10). Together they cover stance, weight, and aero for the facelifted S550 body.
How much weight does a carbon fiber hood save on a Mustang?
A carbon fiber hood typically weighs 30-50% less than the factory panel, cutting roughly 10-15 lbs off the front of the car. That weight comes off the highest, most forward point of the chassis, which sharpens turn-in and reduces nose dive under braking — a bigger handling benefit than the same weight removed lower or further back.
Do 2015-2017 Mustang carbon parts fit a 2018-2019 Mustang?
No. The 2018 model year brought the S550 mid-cycle facelift with a new hood and front fascia, so 2015-2017 hoods, fenders, splitters, and grilles do not fit 2018-2022 cars. Always match the part's listed year range to your exact model year and trim before ordering carbon fiber body panels.
Is prepreg carbon fiber better than regular carbon fiber?
Yes. Prepreg carbon fiber is pre-impregnated with a controlled resin-to-fiber ratio and autoclave-cured, producing a stronger, lighter, and more consistent panel than wet-layup carbon. Anderson Composites uses aerospace-grade prepreg with a 2x2 twill weave and a UV-resistant clear coat, which is why the finish holds up in the sun and the panels resist warping.
What does a double-sided carbon fiber hood mean?
A double-sided (DS) carbon fiber hood has finished, show-quality carbon on both the exterior surface and the underside, with no exposed fiberglass backing. It costs more than a single-sided hood but looks complete when the hood is raised at a car show, which is why we recommend DS construction for any street or show S550 Mustang build.
Do carbon fiber body parts add horsepower to a Mustang?
Carbon fiber body parts do not add engine horsepower directly, but they improve the power-to-weight ratio by removing weight, and aero pieces like splitters and diffusers add downforce for grip. On a Gen 3 Coyote GT making 460 hp, dropping 10-15 lbs from a carbon hood and improving front downforce sharpens how the existing power gets used on the street and track.
