Supercars has taken the extraordinary step of appealing the outcome of the investigation into Kai Allen’s tyre pressure breach in Perth. Motorsport Australia stewards recognised there had been a breach but elected to not issue a penalty, something that has infuriated both rival teams and Supercars itself. As a result, the category has decided to appeal the stewards’ call in what is believed to be a first in Supercars history. Andrew van Leeuwen and Stefan Bartholomaeus delve into the sensational saga with some latest updates. They also talk about testing at The Bend where Toyota’s b-spec engine banked plenty of miles, but the Supercheap Auto wildcard didn’t.
