Unlike most GTA mods that add weapons, gangs, or chaos, Pro Street 2011 stripped away the violence. The goal was simple: import a massive fleet of Japanese and European tuner cars, replace the map with racetracks (or re-texture Vice City to look like a closed race event), and overhaul the physics to mimic grip racing rather than arcade drifting.
While original links from 2011 can be difficult to find on primary repositories like ModDB (which hosts other popular overhauls), the mod is still available through enthusiast sites and software archives: gta vice city pro street 2011 link
