You can build a custom Mustang in Gran Turismo Sport through the game's tuning and customization menu
Creating a Ford Mustang in Gran Turismo Sport means purchasing the car first, then modifying its performance and appearance to match your driving style. The game lets you change the engine, suspension, brakes, and tires, as well as paint, wheels, and body kits. You do not need to own a real car or spend real money beyond the game itself — all customization happens inside the game using in-game currency called credits.
The process takes place in the garage menu, where you can access tuning options after you own the car. Different Mustang models appear in the game depending on the version you own, and each one can be modified independently. Your changes stay saved to that specific car, so you can create multiple versions of the same model with different setups.
Key Takeaways
- You must buy a Ford Mustang from the in-game dealership using credits before you can customize it.
- Tuning options include engine upgrades, suspension adjustments, brake improvements, and tire selection, all found in the garage menu.
- Cosmetic changes like paint color, wheels, and body kits are separate from performance tuning and do not affect how the car drives.
- Each customized Mustang is saved as its own car in your garage, so you can create multiple versions with different setups.
- You can test your customized Mustang on any track in the game to see how your changes affect its handling and speed.
Finding and buying a Ford Mustang in the dealership
The dealership in Gran Turismo Sport rotates its inventory, so the Mustang models available change over time. You access the dealership from the main menu under "Garage" or "Shop." Look for Ford in the manufacturer list, then browse the available Mustang models. The game typically includes several generations of Mustang, from classic models to modern versions.
Each Mustang has a credit price listed in the dealership. You earn credits by racing, completing challenges, and winning events. Once you have enough credits, select the Mustang you want and confirm the purchase. The car appears in your garage when ready and is ready to customize.
Accessing the tuning menu and performance upgrades
After you own a Mustang, go to your garage and select the car. You will see a menu with options including "Tune," "Customize," and "Settings." The "Tune" option opens the performance tuning menu, where you can upgrade or adjust the engine, transmission, suspension, brakes, and tires.
Engine upgrades increase horsepower and torque but also add weight and cost credits. You can choose how much power you want — a mild upgrade or a full racing engine. Transmission tuning lets you change gear ratios to suit different tracks. Suspension adjustments control how stiff or soft the car feels when turning and braking. Brake upgrades improve stopping power. Tire selection changes grip and handling characteristics depending on the track surface and weather.
Each upgrade shows its effect on the car's stats before you purchase it, so you can see whether a change helps or hurts your performance. You can undo any upgrade by selling it back, though you lose some credits in the transaction.
Changing the appearance with paint, wheels, and body kits
Cosmetic customization happens in the "Customize" menu. Paint color is the simplest change — you can choose from a wide range of solid colors, metallic finishes, and special colors. Some colors cost more credits than others.
Wheels are selected separately and affect both appearance and weight. Lighter wheels improve acceleration and handling but cost more credits. You can browse wheels by style and size to find a look that matches your vision.
Body kits and aero parts change the car's visual appearance and sometimes its aerodynamics. A racing body kit might add a larger spoiler or side skirts. These changes are purely cosmetic unless the part specifically lists an aerodynamic benefit in its description. You can mix and match different parts to create a unique look.
Testing your customized Mustang on the track
Once you have made your changes, you can test the car when ready by selecting "Test Drive" from the garage menu. This takes you to a practice session on a track of your choice, where you can drive the Mustang and feel how your tuning changes affect its behavior.
Pay attention to how the car accelerates, turns, and brakes. If it feels too loose or too stiff, go back to the garage and adjust the suspension. If it is too slow, consider engine upgrades. If it slides too much, try different tires or brake settings. Testing and adjusting is a normal part of building a car you enjoy driving.
Saving multiple versions of your customized Mustang
Gran Turismo Sport lets you save different setups for the same car model. If you want a Mustang tuned for racing on a road course and a different Mustang tuned for drag racing, you can buy the same model twice and customize each one separately. Both cars appear in your garage with their own names and setups.
You can also use the "Save Setup" feature to store your tuning configuration. If you want to try a completely different approach, you can load a previous setup instead of starting over. This is useful when you are experimenting with different suspension or engine configurations.
Understanding credits and the cost of customization
Every upgrade, paint color, and wheel selection costs credits. The total cost of fully customizing a Mustang depends on how many upgrades you choose and which ones. A mild tune with basic cosmetics costs far less than a full racing build with top-tier engine upgrades and expensive wheels.
You earn credits by racing events, completing challenges, and winning online races. Some events pay more credits than others. If you run out of credits, you can always race more to earn them, then return to customization. There is no time limit on building your car — you can customize it gradually as you earn more credits.
Frequently Asked Questions
Can I undo a customization if I do not like it?
Yes. You can sell back any upgrade, paint color, or wheel from the tuning menu. You receive credits for the sale, though usually less than you paid. This lets you experiment without losing your car permanently.
Do cosmetic changes like paint and wheels affect how the car drives?
Paint color does not affect performance. Wheels do affect performance — lighter wheels improve acceleration and handling, while heavier wheels reduce both. Check the wheel stats before purchasing to see the weight difference.
What is the difference between tuning and customizing?
Tuning changes how the car performs — engine power, suspension stiffness, brake strength, and tire grip. Customizing changes how it looks — paint, wheels, and body kits. Both are separate menus in the garage.
Can I use my customized Mustang in online races?
Yes. Any car you customize in your garage can be used in online races, time trials, and campaign events. Your tuning setup carries over to every race you enter with that car.
How do I know which upgrades are worth the credits?
Test drive the car before and after an upgrade to feel the difference. Engine upgrades add power but weight. Suspension and brake upgrades improve handling and stopping. Tire changes affect grip. Choose upgrades that match the tracks and racing style you prefer.
