2013 Ford Mustang RTR Spec 3 by Mothers

When Vaughn Gittin Jr. launched the 2013 Mustang RTR this past summer he made two versions of the car available. The Spec 1 version featured mostly cosmetic upgrades while the Spec 2 received additional suspension upgrades and an optional supercharger system. What then would a Spec 3 Mustang RTR be like? You’re looking at it here, a 2013 Mustang RTR built by Mothers and Autosport Dynamics. The Spec 3 takes the Mustang RTR to another level with carbon fiber aero components and widened fenders, and an extensively upgraded suspension system including a watts-link at the rear. Inside the car gets even more RTR treatment with a rear seat delete and cross brace, custom Sparco seats and a Reus audio system.
