The cars look nice, but using them for AI offline on any track for racing is terrible. I tried several different type tracks and the AI cars spin off the starting grid and only move about a few feet from the start and stop and dont go anymore. My car moves around ok but nothing to race against, they(AI) all stop. They may work for online with real drivers. I only have time to do AI racing.
Note: I know it is not your car mod, and I am rating the car itself not you who posted the sprint car. It is just a bad mod for AI racing.
