Chaz Mostert and co-driver Fabian Coulthard delivered Walkinshaw TWG Racing’s Toyota GR Supra a landmark endurance win in a rain-lashed AirTouch 500, shortened to 141 laps under time certain after wild weather.
How it was won
A pre-race deluge put co-drivers in for the start. Tim Slade jumped early for Grove Racing before aquaplane drama and Safety Cars shuffled the order. Coulthard starred in the wet, leading mid-race before handing to Mostert.
Mostert charged from deep in the top 10 after the Lap 59 restart to lead once strategy stopped the long-staying Erebus cars. He controlled the drying final stint to beat Kai Allen / Tim Slade (Grove Mustang) by 18.4867s, with teammates Ryan Wood / Jaxon Evans completing a Walkinshaw TWG 1–3.
Mostert called it his first “500” win after years of near-misses; Coulthard described the wet patches as among the wildest conditions of his career.

History & significance
