As last year I will go in from the gate just the other side of Dunlop bridge as I will be in the Dunlop tribune. Last year I was up at the front and next to the teams celebrating.
I got in at a bit after MB, not too far from the podium, about the last corner
That route is fine but usually a couple of minutes slower to open than the ones at the top of MB/under the hospitality area. The MB ones usually open first.
I've been at Porchse curves a number of times and have managed to access the track after the race from both these directions. (see light blue lines on the photo). The small one is a steep climb but quite short and probably the better route.
