Aerodynamics Under Control, Part 3: Mustang S550 with a Rear Wing in CFD Analysis

In the first part of the series, we analyzed the stock Ford Mustang GT 5.0 S550. In the second part, we added canards and showed how small front aero elements can influence local airflow and reduce lift. Now we move on to one of the most recognizable aerodynamic components in motorsport. Part three focuses on the Mustang S550 equipped only with a rear wing. No canards, no complete aero package, and no additional front-end aerodynamic elements. Just the factory fastback body and a rear wing working at the back of the car. This is where the real work begins against one of the biggest aerodynamic challenges of the Mustang S550: airflow behind the roof, rear glass, and trunk lid.

Aerodynamics Under Control, Part 2: Mustang S550 with Canards in CFD Analysis

In the first part of the series, we analyzed the stock Ford Mustang GT 5.0 S550. No additional aerodynamic components, no canards, and no rear wing. Just the factory fastback body, which already showed noticeable lift, disturbed airflow behind the car, and areas that required further aerodynamic control. Part two is the first step toward modifying the airflow. This time, the analysis focuses on a Mustang S550 equipped with front canards. These components are often associated mainly with an aggressive visual appearance, but their real purpose begins where styling ends. Canards operate in one of the most critical areas of the body - around the front bumper corners, where the incoming air starts to split into airflow moving over the car, along the sides, and underneath the vehicle. In this part, we check whether a relatively small front aero component can have a real impact on pressure distribution, lift, and the overall airflow behavior around the Mustang S550.

Aerodynamics Under Control, Part 1: Stock Mustang S550 CFD Analysis

In the world of track-focused cars, a powerful engine, stiff suspension, and strong brakes are no longer enough. At high speeds, something comes into play that you cannot see from the cockpit, but can clearly feel through the steering wheel - aerodynamics. The Ford Mustang GT S550 features a highly distinctive body shape. Its long hood, aggressively raked windshield, sloping roofline, and fastback silhouette create a design that looks stunning, but at high speeds also generates very specific airflow characteristics.

Precision Architecture, Part 5: Rear Lower Toe Link Mustang S550

In the fourth installment of our series, we dive deeper into the rear axle of the Mustang S550. Today, we focus on a component that, despite its small size, has a massive impact on how your car delivers power to the pavement: the Rear Toe Link.

GTM Structural Restoration Underway at Race Rush Garage

The recent track incident closed one chapter but opened another. Today, we present the first phase of work on our flagship Mustang GTM project, currently in the hands of the fabrication and chassis structure experts at Race Rush Garage. Entrusting this restoration to Race Rush Garage was a decision driven by their uncompromising commitment to safety and chassis engineering. This creates the solid foundation required to build the new, enhanced GTM specification.

Precision Architecture, Part 4: The Restomotive Rear Vertical Link in Mustang S550

Precision Architecture, Part 3: Rear Upper Control Arm (RUCA) Mustang S550

We’re moving to the rear axle. If your Mustang suffers from violent vibrations during a hard launch (the infamous wheel hop) or if the rear end feels disconnected mid-corner, the culprit is usually the factory upper control arm-commonly known as "banana." At Restomotive, we re-engineered this component from the ground up to eliminate the biggest weakness of the S550 IRS (Independent Rear Suspension).

Precision Architecture, Part 2: Restomotive Mustang S550 Front Upper Lateral Link

We have already discussed the tension link, which stabilizes the wheel longitudinally. Today, we’re diving deeper into the front-end kinematics of the Mustang S550 to examine the component that dictates exactly how much grip you have at the apex: the front upper lateral link.

Precision Architecture, Part 1: The GTM-Spec Front Lower Radius Arm Mustang S550

In the world of high-performance suspension, there is no room for guesswork. Every bit of uncontrolled movement results in a loss of traction and precious seconds bleeding out on every lap. Today, we’re putting one of the most critical components of the Mustang S550 under the microscope: the front lower tension link, also known as the radius arm.

GTM Evolution: Stock platform limit analysis at Silesia Ring

Our appearance at the first round of the Race Cup had one overriding objective: to identify the breaking point of the stock Mustang platform. We hit the track to put the factory setup to the test under limit conditions. Although our run at Silesia Ring ended prematurely, it provided us with the most critical data for the ongoing development of the 'GTM' project

Traction Engineering: How Öhlins DFV Technology and Restomotive Components Redefine the Mustang GT S550

At Restomotive, we believe that the power of the Coyote V8 engine is only half the battle. The real challenge begins where the tire meets the asphalt. To transform the Mustang GT S550 from a mere straight-line muscle car into a precision track tool, we turned to the most advanced damping technology in the world. We are proud to present the behind-the-scenes look at our Öhlins Road & Track installation and announce our proprietary Restomotive suspension package, developed in close cooperation with Swedish engineers.

TIG, Argon, and V8: Behind the scenes of the Mustang GT exhaust production.

In our previous posts, we showed you how we bring the Mustang GT chassis into the digital world through 3D scanning and how we optimize exhaust flow within a CAD environment. However, even the most brilliant design is nothing more than a file on a drive until the welder steps in. At Restomotive, welding isn't just a production stage. It is the moment where AISI 304L stainless steel takes its final shape and develops the durability required to withstand the punishing conditions under a Mustang GT.
