Ford Mustang GT500 StyleR ear Bumper Body Kit Conversion w/ Diffuser（2013-2014）
Fitment & Compatibility
Vehicle Fitment: 2013–2014 Ford Mustang (all trims – V6, GT, Boss 302, etc.)
Style Upgrade: GT500 style rear bumper conversion – gives your S197 Mustang the aggressive, planted rear stance inspired by the Shelby GT500, complete with an integrated diffuser.
Free Compatibility Check: Not sure if this fits your specific Mustang? Send us your VIN and a photo of your car’s rear end before purchasing. We’ll verify fitment for free to help you avoid order mistakes.
Material & Finish
Material: High‑quality polypropylene (PP) – durable, impact‑resistant, and ready for painting. PP offers the flexibility and strength needed for daily driving.
Finish: Unpainted – requires painting to match your vehicle’s factory color code or your desired custom finish.
Diffuser Finish: The integrated diffuser is made from the same PP material and also ships unpainted, allowing you to paint it body‑color, satin black, or any custom shade.
Paint Preparation: The surface is ready for sanding, priming, and painting. Minor transport scratches may occur; these can be easily resolved during the normal prep and painting process.
Included Components
Complete GT500 style rear bumper body kit – includes the rear bumper cover and integrated diffuser as a single assembly (exactly as shown in the parts diagram)

Installation & Professional Requirements
We highly recommend professional installation for all body kit products.
Before painting or final installation, a full test fit is required to ensure proper alignment and fitment. This step is essential, as painted parts are considered modified and may not be eligible for return.
Important Notes:
Do not paint the item before test fitting
Minor adjustments, sanding, or trimming may be required for optimal fitment
Professional body shop installation is strongly recommended
Installation instructions are not included
If you are unsure about fitment, please contact us with your VIN before installation.
Design & Development Philosophy
The 2013–2014 S197 Mustang is one of the most aggressive‑looking generations from the factory – but the GT500 rear end takes it to another level. We developed this rear bumper kit with integrated diffuser to give every 2013‑2014 Mustang owner that dominant, track‑ready stance without the factory GT500 price tag.
1. True GT500 Rear Aesthetic
We studied the GT500’s rear fascia – the deeper lower valance, the pronounced diffuser fins, and the exhaust cutout placement. This bumper replicates those elements while seamlessly matching the S197’s taillight and quarter‑panel lines, so the upgrade looks factory‑intended.
2. Integrated Diffuser – Form + Function
The built‑in diffuser isn’t just for looks. Its contour helps manage airflow under the rear bumper, reducing drag and improving stability at higher speeds. Plus, the aggressive fin design gives your Mustang a menacing, planted appearance from every angle.
3. Complete Kit, No Hidden Parts
We include the bumper cover and diffuser as one assembly – no separate pieces to align or extra purchases. Everything you need is in the box, exactly as shown in the parts diagram. Just paint, mount, and go.
4. Material Choice – Polypropylene (PP)
PP is the same material class Ford uses for OEM bumpers. It’s impact‑resistant, flexible enough to absorb minor bumps without cracking, and takes paint beautifully. Unlike fiberglass or cheap ABS, this kit is built for real‑world durability.
5. Painter‑Ready & Shop Friendly
We ship the bumper unpainted because we know every build is unique – from factory Deep Impact Blue to custom satin wraps. Minor shipping scratches sand out quickly during prep. Paint it body‑color for a clean look, or leave the diffuser in matte black for a bold contrast. The choice is yours.
6. Built for S197 Enthusiasts
We test‑fitted this kit on multiple 2013‑2014 Mustang trims – V6, GT, and Boss 302 – to ensure perfect panel gaps, diffuser alignment, and exhaust clearance. Our goal: a bolt‑on GT500 conversion that turns heads and performs as good as it looks.
