NOLA Motorsports Open Track Following a Newer BMW M4

Following a newer BMW M4 that was on Toyo Proxes R888s that had aftermarket downpipes/tune suspension pieces. I’m in my stock 2019 Mustang GT on regular 275/40/20 320-Treadwear Pirelli G2s. He should have been at least 10-15 seconds ahead of me. As you can see, he was clogging up the line and nearly lost it a couple times and wasn’t taking the correct lines or apexes. This was in Intermediate/Advanced class and he should have surely been in Novice/Beginner.
