2021 Ford Mustang RTR Spec 1

The Ford Mustang RTR Spec 1 combines modern aggressive styling and industry-leading, OEM quality body parts with our Tactical Performance Suspension parts.

The Spec 1 is specifically designed with style in mind. Each part has been engineered to improve the overall look and functionality of the already superior Ford Mustang. In addition to the added appearance parts, the Spec 1 enhances the suspension of the Ford Mustang with the same stance featured on the Spec 2. All Spec 1 components have been track-proven and validated by professional Ford test drivers and Formula Drift Champion Vaughn Gittin Jr.

When designing the Ford Mustang RTR Spec 1 it was essential that each part on the vehicle would have a specific purpose. Keeping functionality in mind, there is also plenty of signature RTR style included in the RTR package, starting with the iconic RTR Upper Grille with LED Lighting, and Lower Grille. 

Not only are these grilles designed for style, but they also increase airflow to the radiator for improved engine cooling and performance. All RTR Spec Packages also include exclusive badging and graphics that set the Spec 1 apart from all others on the road. 


Every non-MagneRide equipped Spec 1 Mustang includes RTR Tactical Performance Lowering Springs - the same springs offered on the Spec 2 package. These springs improve handling and performance through a lower centre of gravity and progressive spring rate, giving the Spec 1 the perfect fitment for a set of RTR wheels. Ford Performance MagneRide Springs are fitted to MagneRide-equipped vehicles.

The Spec 1 features either Matte Charcoal or Gloss Black 19” RTR Tech 5 or Tech 7 wheels, retaining the stock tyres.

The factory Ford shift knob is replaced with a Black 6 Speed Shift Knob with our RTR logo engraving (manual only). To complete the sleek, personalised style of the Ford Mustang RTR each Spec 1 receives a serialised dash plaque that is personally autographed by Vaughn Gittin Jr.
