My Multi Theft Auto San Andreas map you can use on your server, when you have race gamemode.
i used Ferrari 488 Spyder 2016 car for the map - you can download it here : http://www.gtainside.com/en/sanandreas/cars/112190-ferrari-488-spider-2016/
You don't need to enable any mods, modloaders etc. on your server = already map is scripted and Ferrari will automaticly load.
Paste it on - MTA San Andreas/Server/Mods/Deathmatch/Resources
