A New Chapter: From oldschool to newschool

The decision to enter the world of the S550 model stems from our desire to meet the needs of drivers seeking professional, track-ready preparation based on a modern and more accessible chassis. The Mustang GEN6 is a platform with immense potential, which – much like its ancestors from the 1960s – requires precise “refinement” to fully hold its own in Time Attack races or professional cup series.
Our Mustang GT Track-Spec project has become our ultimate testing ground. This car is not just a showpiece; it is our mobile laboratory. At the heart of the machine lies the MF8F Coyote 5.0 V8 unit, which we have paired with the lightning-fast 10-speed 10R80 transmission. Our goal is clear: to create a stable setup pushing 500+ HP that can withstand the rigors of the most demanding track sessions.

Mustang in Global Motorsport: Inspiration from the World’s Circuits

When designing our components, we don’t act blindly. We analyze data from the world’s most demanding racing series, where the Mustang S550 has already proven its absolute effectiveness. Our solutions draw from the experience of series such as the IMSA Michelin Pilot Challenge and the GT4 European Series, where the Mustang GT4 sets the benchmark in endurance racing.

We closely study the technical precision required in the British GT Championship and the durability tested in the “Green Hell” during the Nürburgring Langstrecken-Serie (NLS). Our aerodynamic developments are inspired by the aggressive lines of the Australian Supercars (Gen3) series, and we verify chassis stiffness based on the standards of the brutal SCCA Trans-Am series. Even insights from Formula Drift allow us to better understand the lateral G-forces the S550 body is subjected to. All of this ensures that cars equipped with Restomotive parts remain unrivaled.

Phase One: Ready for the Race Season

With the season fast approaching, we have prepared a package of modifications for March that radically transforms the Mustang GT’s characteristics, eliminating its factory “bottlenecks.”

Power, Breathing, and Calibration To allow the Coyote engine to fully spread its wings, we implemented an advanced intake system to maximize mass airflow. This system works in conjunction with our proprietary Restomotive exhaust system, designed for reduced backpressure and significant weight savings. The entire setup is tied together by individual ECU and TCU calibration. Optimizing engine maps and recalibrating the 10R80 gearbox shift points ensures the drivetrain reacts significantly better than the stock version.

High-Downforce Aerodynamics Our aero package is a complete ecosystem where function strictly dictates form. In designing the Flat Underbody kit, we drew direct inspiration from the ground-effect technologies used in Formula 1. The key lies in managing the airflow beneath the car to create a low-pressure zone. Just like in the pinnacle of motorsport, our solution “sucks” the car to the tarmac, drastically improving high-speed cornering stability without the penalty of excessive drag from oversized wings. The front splitter, working in tandem with the canards, precisely manages airflow to reduce aerodynamic drag and understeer.

Suspension and Traction Without Compromise Factory Mustang settings are far too conservative for the track. We are introducing Camber Plates, which allow for an aggressive negative camber setting, protecting the tire shoulder and increasing cornering grip. Our set of adjustable control arms ensures precise geometry that factory components simply cannot provide. A key element is also the rear subframe reinforcement (Rear Subframe Inserts) – we eliminate the deflection of factory rubber bushings, ensuring the “rear” of the car reacts instantaneously to every driver command. The package is completed by Semi-Slick tires, transferring the generated power directly to the asphalt.

What’s Next?

The goal is clear, and we are committed to making March the beginning of our journey with the S550 platform. Throughout the season, our test car will be equipped with further innovations: a dedicated rear diffuser to complete the underbody aerodynamics package, and our proprietary intake system, which is currently under development.

At Restomotive, we believe that engineering is a continuous process. We invite you to follow the build of our Mustang GT Track-Spec – we will be regularly publishing test data and track times, proving that our parts provide a tangible edge on every lap.
