2015-2017 Ford Mustang • GT • V6 • EcoBoost
The OG FFP splitter that started it all. CNC-engineered hybrid aluminum construction delivers real downforce without adding weight. Fully customizable with support rods, edge trim, and side fins.





Engineering Excellence
Worried about adding weight? Don't be. This splitter is crafted from automotive-grade hybrid aluminum — incredibly lightweight yet durable enough to handle whatever you throw at it.
The "Under-Tray" design increases downforce by directing high-pressure air over the vehicle and low-pressure air underneath. The result? More traction, better cornering, and improved grip.
Features a gloss black finish on one side and satin black on the other — giving you options right out of the box. And unlike competitors, this splitter does NOT block your factory oil drain plug or filter access.
Key Features

INSTALLATION GUIDE – CLICK HERE
This Function Factory Performance front splitter is designed to keep your 2015-2017 Ford Mustang GT, V6, or EcoBoost planted to the ground at any moment of driving. Worried about adding weight? This front splitter is extremely lightweight and durable due to the hybrid aluminum material it is made of. This front splitter increases downforce by sending the high-pressure air over the vehicle, and the low-pressure air under. This increases traction, cornering, and grip.
BEFORE MAKING YOUR PURCHASE, PLEASE READ THE DISCLAIMS BELOW – Updated 05-17-2021
PROFESSIONAL INSTALLATION IS REQUIRED. The user assumes full responsibility for ensuring proper installation as intended. To ensure proper function and reliability, Function Factory Performance and Liquivinyl advises you to choose a professional body or performance shop for proper installation. Failure to do so can lead to a serious failure in the splitter, front bumper, and underbelly. The vehicle application shown above is intended to work as a complete system when installed onto original vehicle body parts (i.e. front bumpers, air dams, etc.).
BENT OR DAMAGED SPLITTERS DURING SHIPPING. If your front splitter is damaged during shipping, please immediately photograph the damage and send the photos to support@ffperformance.co
This must be done within 72 hours or we are unable to file a claim. You will receive a new splitter, free of cost but you must keep your own original hardware, side fins, and or rods.
