Various packages are available for the current-generation Ford Mustang – starting with what RTR calls the Design package. It starts at $6,995 on top of the price of your Mustang and adds a unique grille, LED lights around the front air intakes, unique 19-inch wheels, a decklid spoiler, a windshield banner, a dash plaque, and some additional RTR badging. Essentially, it’s a cosmetic package. From there, RTR offers Spec packages – 1, 2, and 3. The Spec 1 package ($11,495) gets most of the Design package’s equipment along with lowering springs, an upgraded shift knob, RTR floor mats, upgraded tires, unique lug nuts, and a special clam shell for your Mustang’s key fob.

Specifically for Mustang GT models, the Spec 2 ($17,995) adds hood vents, front splitters, unique front bumper grilles, adjustable sway bars in the front and rear, adjustable front struts and rear shocks, and 20-inch wheels with staggered width (20×10.5 in the rear, 20×9.5 up front). There are also a number of one-off parts available if you’re looking to upgrade your Mustang at a slower pace or without such a big financial commitment upfront. And at the top of the customization lineup for RTR Mustangs is the Spec 3 package which adds a whopping $32,995 to the price of your regular Mustang GT, but it’s not just for looks.

For the most part, the RTR Design and Spec 1 packages are appearance-oriented – even RTR labels them that way. The Spec 2 package goes a bit further with suspension modifications, but the Spec 3 is an entirely different animal. Under the hood, a 3.0-liter Whipple supercharger is added to the mix, which is a serious performance upgrade. A standard 2025 Ford Mustang GT with a 5.0-liter V8 produces 480 horsepower and 415 lb-ft of torque. The Spec 3 RTR Mustang claims that the supercharger increases those numbers to 810 hp and 615 lb-ft of torque. An X-Pipe exhaust is available on all three Spec models.

Like the Spec 2, the Spec 3 gets all sorts of cosmetic upgrades and many of the same suspension components like adjustable sway bars and shocks. And, like some other RTR packages, the Spec 3 gets high-performance Nitto tires. On Spec 2 and Spec 3 cars, several custom paint colors are available via RTR’s Paint To Sample program, but prices are pretty steep depending on which package you go with. Any one of their standard paint jobs will run $8,995, while Premium paint is $14,995, and custom-selected colors will cost $5k more than the standard or premium paint, depending on the color. They aren’t cheap, but RTR Mustangs are highly customizable, and they can still be serviced at your local Ford dealer.
