Here we are on board in my 991.2 GT3RS with Jonny Cocker behind the wheel showing me exactly what my car can do with virtually no trick bits. All I have is Manthey Racing brake pads, lines and fluid and the car is on 4 track day old Michelin Cup2’s Porsche spec. As you can see, in places it’s a handful so now we have the base line data thanks to the VBOX Video Hd2, we can now start improving the car.
