If you download the mod, you will get the Nissan Silvia car style from Need for Speed 2015 in the garage. This is the same Silvia SpecR for Payback, it was demonstrated from EA screenshots in Need for Speed 2015.
After you download the mod for Nissan Silvia SpecR, open the archive. In it you will see an archive with the Frosty Mod Manager program of the required version, and the second one with a car.
The installation is simple and well-known, but we want to remind you that you need to check the box and start the Need for Speed Payback game one by one. To avoid stupidity! And just like other mods for cars, just go to a racing car dealership and purchase for $0.
