Now You Can Be The Proud Owner of A 472 Horsepower Mustang RTR

The Mustang RTR is Vaughn Gittin Jr.’s production interpretation of the car he drifts for a living, and its tiers differ by considerably more than badges. The 472-horsepower figure attached to the GT comes from Ford Performance hardware rather than a third-party tuner, which is precisely why the factory warranty survives the upgrade intact. Read on for what separates Spec 1 from Spec 2, and why the suspension work may matter more than the power does.

Ford has attached a great many names to Mustang fenders over the past sixty years, and nearly all of them originated inside the building. This one did not. It came from a driver who built an entire professional career out of deliberately never pointing the car where it was going, and when Ford handed him a production program the obvious risk was that the result would amount to body panels, a set of wheels, and a signature on the dash. The horsepower figure attached to the upgraded cars suggests something more substantial happened instead, and where exactly that number comes from turns out to be the most interesting detail in the whole program.

The Number on the Window Sticker Comes From Ford

The 472 horsepower figure is not a tuner’s dyno claim. A 2015 through 2017 Mustang GT left the factory with the 5.0-liter Coyote V8 rated at 435 horsepower and 400 lb-ft of torque. Ford Performance sells a Power Pack consisting of a cold-air intake and a recalibrated engine tune that raises that to roughly 472 horsepower, and it carries a Ford part number. That distinction is the foundation everything else in this program rests on, because a Ford-engineered calibration sold through Ford’s own performance catalog occupies a very different position than an aftermarket flash from a shop nobody at the dealership has heard of.

Who Vaughn Gittin Jr. Actually Is

Vaughn Gittin Jr. built his reputation in Formula Drift, where he became a champion driving Mustangs sideways at competition speed, and he did it in an era when the sport was still establishing whether it was a discipline or a spectacle. RTR Vehicles grew out of that work as an attempt to translate the aesthetic and, more importantly, the chassis philosophy of a competition drift car into something a person could finance at a dealership. The name itself stands for Ready To Rock, which sets expectations about the tone of the enterprise fairly efficiently.

Spec 1: Everything You Can See

Spec 1 is the appearance tier, and it is honest about that. Buyers get the RTR grille with integrated lighting, a chin spoiler, rear spoiler, aero elements, RTR wheels, and the badging that identifies the car. The engine and suspension are left as Ford built them. There is a temptation to dismiss a package like this, but it serves a real purpose for someone who wants the look without changing how the car behaves, keeps insurance conversations simple, and leaves every mechanical upgrade path open for later. It is the entry point, priced accordingly.

Spec 2: Where the Hardware Starts

Spec 2 is where the program stops being cosmetic. It layers RTR Tactical Performance suspension components over the Spec 1 appearance content, including adjustable sway bars and revised springs that lower the car and change how weight transfers during cornering and throttle application. On GT cars it also brings the Ford Performance power upgrade that produces the 472 horsepower figure. The combination is what the RTR reputation actually rests on, because it addresses the two things that determine how a rear-drive car feels when driven hard: how much power it makes and how predictably it puts that power down.

Why the Factory Warranty Survives

The warranty question is the one that separates this from the broader tuning world, and the answer is straightforward. Because every component comes through Ford Performance and the work happens within the dealer network rather than in an independent shop, factory coverage remains intact. Anyone who has argued with a service department about whether an aftermarket tune caused a drivetrain failure understands why that matters. It removes the single largest financial risk of modifying a new car, and for a substantial number of buyers it is the deciding factor rather than a footnote.

Buying a Modified Mustang Through a Dealership

The purchasing process reflects the same logic. An RTR is configured and delivered through participating Ford dealers, which means the cost of the modifications is folded into the vehicle purchase and financed alongside it rather than paid separately after the fact. Practically speaking, that turns a build that would otherwise consume months of ordering parts and scheduling installation into a single transaction with a delivery date. It also means the car arrives assembled correctly, which is not a trivial advantage given how many owner-installed aero packages end up slightly misaligned.

What the Coyote Gives Up and What It Gains

The Coyote is a good candidate for this treatment specifically because it is naturally aspirated and revs freely. Adding an intake and a calibration extracts power from the top of the range without touching internal components, raising cylinder pressures dramatically, or eating into the reliability margin Ford engineered in. The gain is real but modest in percentage terms, roughly thirty-seven horsepower, and it arrives in the part of the rev range where a driver is already asking for everything. What it does not do is change the engine’s character, which is arguably the point of leaving it naturally aspirated in the first place.

The Suspension Work That Matters More Than Power

The suspension work deserves more attention than the horsepower does. The S550 generation was the first Mustang sold with independent rear suspension, a change that transformed how the car handled bumpy roads and how predictably it behaved at the limit. RTR’s components target roll stiffness distribution and turn-in response rather than simply lowering the car for appearance. On a vehicle built around the idea of controlling the rear axle with the throttle, sway bar balance and damping quality determine whether the car feels communicative or merely nervous, and that is not something an extra thirty-seven horsepower can fix.

Above Spec 2, Where the Superchargers Live

Above Spec 2 the program moves into a different bracket entirely. The higher tiers add supercharging that pushes output well past 700 horsepower, along with adjustable coilovers and more aggressive chassis hardware. Those cars are built in smaller numbers, cost substantially more, and demand a driver who genuinely wants the commitment. They exist partly as halo products and partly because the market for very fast Mustangs has proven consistently larger than anyone expected, but they are not what most people mean when they say they want an RTR.

Who This Car Is Genuinely For

The buyer this makes sense for is specific and fairly common: someone who wants a Mustang that does not look like every other Mustang in the parking lot, wants the handling to match the appearance, and has no interest in becoming the project manager of their own build. That describes a lot of people. The RTR program’s real achievement is not the horsepower number on the badge but the fact that it made a properly sorted, visually distinct, warranty-covered performance Mustang something a person could simply order and then drive home.
