Championship contender Chaz Mostert has been stripped of his second-place finish in Race 2 of the Sydney Supercars event, officials confirmed Monday. The disqualification stems from a technical infringement relating to Tyre Pressure Monitoring System (TPMS) sensors on his Walkinshaw Andretti United Supra.
According to a statement released by Supercars officials, the issue centered on the failure to fit operational TPMS sensors to the control tyres as mandated by Rule D17.1.19. While acknowledging that the failure wasn’t necessarily intentional or aimed at gaining a sporting advantage, the rule requires functioning sensors whenever control tyres are affixed to the vehicle. Officials determined the sensors were not fitted at all, rather than being non-operational due to an external factor.
The disqualification elevates Broc Feeney to the race win, marking a dramatic start to the Supercars season. The race was already described as chaotic, with multiple incidents impacting the field. Feeney’s victory in the Sydney 500 opener was confirmed amidst the fallout from Mostert’s penalty and reports of a separate incident involving hospitalisation, though details of that incident were not immediately available.
The Supercars Championship is currently underway in Sydney, with further races scheduled throughout the week. The Walkinshaw Andretti United team has yet to publicly comment on the disqualification, and it remains unclear whether they intend to appeal the decision. The focus now shifts to the remaining races of the Sydney event and the implications of this penalty for Mostert’s championship aspirations.
