try this one its much better https://www.racedepartment.com/downloads/bathurst-gt3-and-v8sc-ai.44048/Could you have a look at some of the Reboot tracks? On Bathurst the AI seem to slam the anchors on going into the Mcphillamy Park and then brake way too hard going into Skyline. Also, on Suzuka they seem to brake suddenly going into 130R and are a bit too cautious going into the final chicane. Both tracks the AI are fine around the rest of the circuit but I annihilate them in each of those sections rendering the racing experience a tad redundant.
Also try any of the ai lines from that user, they are all pretty good
