Go behind the scenes of a dramatic day of Supercars action in Christchurch with our Sunday edition of the daily podcast.

The New Zealand double-header came to a wild end as a heartbreaking engine failure gifted the Jason Richards Trophy to Broc Feeney.

But not before late drama as Chaz Mostert and Brodie Kostecki came to blows in a bizarre incident prompted by the reigning champion.

Meanwhile, Matt Payne and Grove Racing were in a league of their own, as the team scored its first-ever one-two finish.

Andrew van Leeuwen and Stefan Bartholomaeus have their say on it all.

They also discuss whether the inaugural Christchurch event was a success and if the NZ double-header works.
