AMPP Speed Style Rear Bumper Diffuser – Suit 2023–2027 Ford Mustang S650 GT / EcoBoost
Give the rear of your S650 Mustang a sharper, more aggressive appearance with the AMPP Speed Style Rear Bumper Diffuser.
Designed specifically around the factory Ford Mustang S650 rear bumper, this diffuser follows the original bumper contours and adds a more purposeful, performance-inspired look with its deep fin blades and distinctive centre-slot design.
Finished in smooth matte black, it can be installed as supplied or professionally painted to suit your build.
Other rear diffuser styles are also available.
✅ Vehicle Compatibility
Vehicle: Ford Mustang | Year: 2023–2027 | Chassis: S650 / FO | Body: Coupe / Convertible | Engine: 5.0L V8 GT / 2.3L EcoBoost
✔ Suits Ford Mustang S650 GT V8 models
✔ Suits Ford Mustang S650 2.3L EcoBoost models

✔ Designed for use with the factory rear bumper
🛠 Injection-Moulded Plastic Construction
Manufactured from durable injection-moulded plastic, this AMPP Speed Style rear diffuser is designed for everyday road use while maintaining a clean and integrated appearance.
The moulded construction allows the diffuser to closely follow the factory rear bumper shape while providing the strength required for an underbody component exposed to airflow and everyday road conditions.
✔ Smooth matte black finish
✔ Aggressive rear fin blade and centre-slot design
✔ Injection-moulded plastic construction
✔ Designed around the factory bumper profile
✔ Paintable if a colour-matched or custom finish is required
The extended diffuser fins provide a functional aerodynamic-style design that helps manage and guide airflow travelling underneath the rear of the vehicle at higher speeds.
🔧 Easy Factory-Style Installation
Installation is designed to make use of the Mustang's existing factory mounting locations.
The diffuser features recessed mounting slots positioned around the original bumper bolt locations, allowing the factory mounting positions to be reused for a strong and secure installation.
This is particularly important for a rear diffuser, as this area is constantly exposed to significant airflow underneath the vehicle while driving.
✔ Uses existing factory bolt locations
✔ No complicated custom mounting system
✔ Recessed mounting points for a clean installation
✔ Can be installed using basic hand tools
✔ Approximately 10-minute installation for someone familiar with basic automotive work
We recommend trial-fitting the diffuser and checking all mounting positions before fully tightening the hardware.
Professional installation is recommended if you are unsure.
📦 What’s Included
1 x AMPP Speed Style Rear Bumper Diffuser
🔎 Why Choose the AMPP Speed Style Diffuser?
Rather than using a universal or cheaply made alternative rear diffuser, this piece is specifically designed around the Ford Mustang S650 factory rear bumper.
The aggressive centre section, centre-slot design and outer fins add more depth and definition to the lower rear bumper, giving the Mustang a wider and more performance-focused appearance.
It works particularly well on modified street cars, lowered Mustangs and builds fitted with aftermarket wheels, spoilers, side skirts or other exterior styling upgrades.
A simple and effective way to give your Mustang GT or EcoBoost a more aggressive rear-end appearance without replacing the complete rear bumper.
