About This Brand

RTR - Ready to Rock
The vision for RTR was born when Vaughn realized an entire car culture existed inside the Mustang community, and he had found himself right in the middle of it. He saw that enthusiasts like him wanted a more personalized touch for their vehicles, but there were limited styling options available, and none met his vision of what Mustang could be.

Being “Ready to Rock” is something that Vaughn has said since he was a teenager. It’s a mindset—a way of life—to be ready for anything. This is in the DNA of every RTR vehicle built to drift, drag, cruise, off-road, or run the track with RTR’s signature, modern, aggressive styling.

The world has learned that RTR manufactures to the highest OEM standards. Their parts are tested and validated by professional drivers in extreme & motorsport conditions. That hands-on experience translates into versatile total performance systems; all RTR products are designed and engineered to work together instead of just as one-off parts.

RTR lives by the phrase "Available to All, Not for Everyone" and they mean it. The team at RTR designs and builds very special cars for very special people. We know that not everyone is meant to be an RTR owner—and that's exactly the point.
