Currently, only a select roster of just 11 cars can receive conversion mods from Hao's Special Works. But of course, considering how much these performance upgrades improve the overall experience of driving your car, from handling to accelerating, it all comes at a steep price. Furthermore, it's very likely that Rockstar will add more cars to the roster soon - not only will that attract more people to the DLC, but also make HSW-exclusive races a lot more fun!
