Built Specifically for Customer Racing

The philosophy behind the Gen 7 Mustang GT4 differs significantly from factory-backed GT3 programs. Instead of creating an expensive manufacturer-exclusive race car, Ford and Multimatic engineered a platform that private teams can purchase, operate, and maintain throughout a racing season without requiring factory-level resources.

Customer racing has become one of the fastest-growing sectors in international motorsport, and GT4 regulations emphasize relatively controlled performance while encouraging close competition between different manufacturers. This makes mechanical reliability, operational simplicity, and running costs nearly as important as outright performance.

The Mustang GT4 was therefore engineered with several priorities in mind:

Immediate race readiness
Long-term durability
Straightforward servicing
Affordable operating costs
Global parts support
Consistent performance across varying circuits and championships

These principles have allowed customer teams to remain competitive without requiring massive engineering budgets.

Motorsport Heritage

Few performance cars carry a racing legacy as rich as the Ford Mustang. Beginning with Carroll Shelby’s legendary GT350 race cars in the 1960s, the Mustang quickly became an icon of American motorsport. Over the decades, the platform has competed in Trans-Am, NASCAR, IMSA, SCCA, endurance racing, Australian championships, and numerous international GT categories.

The Gen 7 Mustang GT4 continues this tradition by serving as Ford’s global customer racing platform beneath the flagship Mustang GT3 program.

Rather than being a modified production vehicle, it shares engineering philosophies with Ford’s top-level endurance racing efforts while remaining accessible to independent teams.

Early Racing Success

The Mustang GT4 made an immediate impact when it debuted in January 2024 during the opening round of the IMSA VP Racing SportsCar Challenge at Daytona.

Customer team KohR Motorsports immediately demonstrated the car’s competitiveness by taking victory in its very first race. The following day, the team secured another win, proving the performance was no accident. Those victories marked one of the strongest competition debuts ever achieved by a modern Mustang race car.

Momentum continued throughout the season as the Mustang GT4 captured:

IMSA VP Racing SportsCar Challenge GSX Drivers’ Championship
GSX Teams Championship
GSX Manufacturers’ Championship
Six race victories during the season

Internationally, the platform also excelled. In Canada, Polito Racing dominated the FEL Motorsports Sports Car Championship, winning eight of ten races and claiming the championship. Australia quickly embraced the platform as Miedecke Motorsport earned victory during the Mustang GT4’s first appearance in GT4 Australia.

The momentum continued into 2025 when Academy Motorsport secured the Mustang GT4’s first GT4 European Series victories at Paul Ricard and Zandvoort, while Gomersall Motorsport captured the Monochrome GT4 Australia Silver-Am Championship.

These achievements highlight the car’s versatility across different circuits, climates, and racing series.

Powertrain

At the heart of the Mustang GT4 lies one of Ford’s most celebrated engines—the naturally aspirated 5.0-liter Coyote V8. Unlike turbocharged competitors that often rely on forced induction for power, the Mustang GT4 retains the immediate throttle response and linear power delivery that naturally aspirated engines are known for.

The race-prepared engine incorporates numerous motorsport-specific upgrades to maximize durability under continuous high-load conditions. Key powertrain components include:

Component	Specification
Engine	5.0L Naturally Aspirated Coyote V8
Engine Management	Bosch Motorsport MS6.3 ECU
Lubrication	Dry sump oiling system
Clutch	Twin-plate Tilton Racing clutch
Transmission	Holinger six-speed sequential racing gearbox
Gear Shift	Pneumatic paddle shift system

The dry sump lubrication system ensures consistent oil pressure during sustained high-speed cornering, while the Holinger sequential gearbox delivers lightning-fast shifts suitable for professional endurance racing.

Chassis Engineering

The Mustang GT4’s chassis has been comprehensively redesigned beyond the standard production Mustang. Multimatic’s engineering expertise is evident throughout the suspension package, which focuses on maximizing tire contact, driver confidence, and adjustability.

Highlights include:

Multimatic DSSV two-way adjustable dampers
Coil-over rear suspension conversion
Unique rear lower control arm geometry
Front and rear blade-adjustable anti-roll bars
Motorsport-grade suspension mounting points

One of the standout features is Multimatic’s patented DSSV (Dynamic Suspensions Spool Valve) damper technology. Unlike traditional shim-based dampers, DSSV dampers provide exceptionally precise damping characteristics, greater consistency over long race distances, and simplified tuning for different circuits.

Braking System

The braking package has been engineered for endurance-level durability.

Major components include:

Brembo racing calipers
Large Brembo brake discs
