It depends of what you want to do with your game. Zaz tool is a box tool with several programs inside:
-CSM: Allows you to install and play with mods and to change settings for the game.
-TSM: Allows you to install new tracks easily and to re-order them (you can also install trackspacks) or make your own season's tracks.
-Easywad: You can modify your cars.wad (by adding new cars, helmets, cockpits, tyres etc...)
-Slimtex: you can change size of the textures, for example.
Zaz Tools is necessary when you play CSM mods.
If you are playing with no csm mods, you can use other tools to change settings.
Personnaly, I play no CSM mods but I use Zaz tools and only TSM to install new tracks, Wadupdater to modify my cars.wad and Team Editor to modify Cameras, tyres, helmets and steering wheels positions, performance file and team file...and Texresizer to modify size of the textures if needed...So, you have diffrent possibilities to configure and compile your game...
In the two cases (CSM or no CSM), there are tutorials into the GP4 faq of the site to modify your game or to install CSM mods.
