Turn 13 is a fast left-hand kink in the middle straight.  This corner also forms part of the apex/exit of the b-track cut-thru.  Feel free on the ride through this high-speed corner to grab as much of the inside kerb as you like, it’s possible to cut this corner so much that you are floating across the grass on the inside.  Be warned thou on a dewy morning you’ll most likely end up backwards in the tyres or across the track to Turn 14.

The speed and angle through this corner is important to setup the great passing opportunity in Turn 14.
