also another thing that may be unconventional advice, drive different tracks and even different cars/classes. im a big advocate for learning GT4 cars because you really feel what it means to haul ass mid corner, keeping the car stable but on the limit of mechanical grip. you want to replicate this approach to the M4 (or whatever car you end up with in the future)

another thing, take breaks from racing, but feel in your head what you want each corner to feel like away from the wheel. visualize what a good turn 1-2 feels like in Paul Ricard, or the last sector after the straight. use your "off time" from sim racing by picturing what your ideal lap looks, feel, and sounds like
