The tool itself is located right in the game folder (usually, in Program Files\Steam\steamapps\common\Street Legal Racing Redline v2.3.1) and named "WorkshopInstaller.exe".

You need to pass through the following steps to install workshop mods into the game:

1. Subscribe to items you'd like to install
2. Steam downloads these items first, that takes some time depending on your internet connection speed
3. Run the tool and install the items

To subscribe to workshop item, you need to open its page in Steam workshop and press green "Subscribe" button:


After that, Steam will begin downloading the item, try running workshop installer in about 2-3 minutes (Steam client must be running and you must be logged in into your account):


Once the tool has successfully initialized, you'll get into this window:



Press "INSTALL" and don't interrupt the installation:


When done, you'll receive the message:


To uninstall the item, press "REMOVE":


In some cases you may face with items like this:



An another important thing: if you're making a mod, always watch your directory structure, i.e. if you're making a car, you must make a "cars/" directory and put your car data there, if it's a map, put it to "multibot/maps/", etc., because the installer is copying all your files and folders right into game directory.

If workshop item is replacing original game files, installer will keep their backups.
