RTR Just Made the Mustang Even Easier to Turn Into Your Own Chaos

You’d think Ford’s Mustang lineup would already cover every kind of buyer. RTR disagrees. The company’s latest addition is called the Signature Package, created for owners of RTR Spec 2 and Spec 3 cars who want something tailored more closely to their own taste.

Instead of choosing from a fixed setup, buyers can work directly with RTR on details like graphics, painted aero parts, wheel finishes, and even colored LED intake lighting. Somehow, bright green wheels are only the beginning of the customization options.

From the splitter to the diffuser, RTR lets buyers color-match most of the exterior add-ons. It changes the whole vibe of the Mustang and makes it feel much less factory-looking.

There’s actual hardware behind the styling too. RTR fits its Tactical Performance Coilovers with adjustable ride height and 30-way damping adjustment, so owners can dial the car in however they want. Low and stiff for canyon roads, softer for daily driving, or somewhere in between.

Pricing for the Signature Package starts at $12,500 before adding it to an RTR build. The Spec 2 package starts at $18,995, while the Spec 3 jumps to $33,995 thanks to a Whipple-supercharged 5.0-liter V8 pushing out 810 hp and 615 lb-ft of torque. Giving people this many options almost feels dangerous.
