When designing the 2021 Ford Mustang RTR Spec 1 it was essential that each part on the vehicle would have a specific purpose. With keeping functionality in mind, there is also plenty of signature RTR style included in their 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 dealer-built RTR Spec Packages also include Dealer Only parts, badging, and graphics that set the Spec 1 apart from all others on the road.

Every Spec 1 includes RTR Tactical Performance Lowering Springs. The same springs offered on the Spec 2 package. These springs improve handling and performance through a lower center of gravity and progressive spring rate, giving the Spec 1 the perfect fitment for a set of RTR wheels.

The Spec 1 comes standard with a set of Matte Charcoal 19” RTR Tech 7’s wrapped with Nitto NT555 G2’s (275/40R19) but has an optional 20” RTR Tech 7 upgrade available at the time of purchase.
