Supercars legend Scott McLaughlin has blasted the sport's management over Brodie Kostecki's looming split with Erebus Motorsport, saying they should be "ashamed".
Kostecki, who secured his first Supercars championship in November, is set to sit out the upcoming season due to a dramatic falling out with Erebus.
Three-time Supercars champion McLaughlin, who left the Australian touring car circuit to race in IndyCar at the end of 2020, declared his full support for Kostecki.
