Another GT4 machine is on the table, this time the BMW M4. Despite its twin turbo engine, sometimes it s even louder than N.A. engined cars on the track. I was able to make clips at the Hungaroring and Brno Circuit, plus I could spice this project up with onboard footage with the opening 2 laps from the first sprint race in Brno.
