There is no widely known or official "Viper RSR" model from major automakers. The "RSR" designation is most famously used by Porsche (e.g., 911 RSR). Dodge Vipers (SRT, ACR, etc.) are sometimes modified or wrapped in Gulf-style or racing liveries, but not officially called RSR. If you meant a specific custom build, fan art, or GIF set from a game (like Forza , Gran Turismo , Assetto Corsa , or Need for Speed ), please clarify.
There is nothing quite like a Viper RSR during an endurance race like the 24 Hours of Daytona. GIFs featuring glowing red brake rotors against the pitch-black night are a staple for any enthusiast. 2. The Paddock Roll-Out viper rsr gif collection
