These RTR Mustangs seem a bit out of nowhere — but are quickly taking the attention of enthusiasts and fighting for street-cred dominance with the Roush RS2 Mustang, Hennessey HPE700 and even Ford’s King Cobra with Ford Racing parts.

Around since 2009, RTR stands for Ready to Rock — and these ponies certainly are.

Overwhelmingly a style kit, the RTR upgrade does employ the familiar supercharger route to deliver huge horsepower gains to the Mustang GT’s 5.0-liter V8.

The RTR kit is available for the EcoBoost and V6 cars as well. Not exactly click-to-buy like the Roush parts, nor sold in Ford dealers — the RTR parts definitely have a clear vision and sense of style on their side.

“Ford has really done an amazing job with the new 2015 Ford Mustang,” says Vaughn Gittin Jr. “The all new platform has very easily allowed us to mesh RTR’s tastefully-aggressive styling and modified performance to offer our most capable, best-handling fun-to-drive RTR’s to date. If the slightly modified performance of the our Spec 1 is not enough, customers that demand more are sure to get their kicks with the up to 725 horsepower and optional fully-adjustable suspension that allows the driver to easily adjust the balance of the chassis to their liking. We feel we have developed very diverse and refined offerings, which was our number one goal to support the global release of the 2015 Ford Mustang and ensure our customers keep smiling and having fun behind the wheel of his or her RTR.”
