Tuning Mod is the biggest project of my life (2015).
It is a kind of "ZModeler in-game" where you can freely install any model in any vehicle and any part thereof.
Basically, it's a sandbox where you get build from the most neat tuning cars, modified bicycles, to dolphin-motorcycles or monster trucks made of billiard balls, the limit is your creativity. Can also create and download new parts and save and share their vehicles with other people!
Not only that, you can also install different turbos, brakes and tires to change the car's handling as well as a realistic system of tire wear. In addition to other functions such as doors opening up, lower the car, change engine sound etc, all inside your GTA SA.
