How do you put mods on world racing 2

Well, if you want to add a car: go to theborggaming.com or games.reveur.de and find the world racing 2 download section. after downloading the car(s) of your choice, follow the read me in the folder: they should almost always tell you how to install the car. If they don't, just put the folders "addons" and "motoren2" into your game's directory (usually C:\Program Files\Playlogic\World Racing 2\) and allow any overwrites. Or sometimes if there's just a folder of the car, put it in (WR2 Directory\Addons\Autos\).
And if you want a new track or two or ten, find a WR2 mod website, download the mod, and then go to krom.reveur.de and download the latest version of World Racing 2 Manager, and the read mes should tell you from there.
Good luck, there's a lot of cool mods out there.
