I don't understand how you can control a Volvo with LS7? It's a crazy car! Maybe it's because I'm using a gyroscope controller, which means the wheels rarely stay straight. This is the only car in the game I've ever managed to flip, without crashing, just the stiff suspension and sharp turns. Before that, I didn't even know cars could flip in GT7.
I'll try your settings, maybe then I'll be able to get it to handle.
The controller and automatic transmission aren't a limitation. I also drive with a controller (gyro) and most often with automatic transmission (sometimes MT), and the level is always difficult. The only reason I might not win is a lack of practice while getting used to the track and a new car. Understanding the real physics of car control has been a big help for me. The last thing that improved my driving skills is this article:
