Tickford Racing star Chaz Mostert admits he's unsure if his team can deliver a championship-winning car that will keep him on their Supercars roster next season.
Mostert's commitment to the team giving him his start is uncertain amid speculation he'll join rivals and fellow Ford customer DJR Team Penske.
It is understood the 27-year-old is talking to other teams, which is allowed because he is off contract at the end of the season.
Former Bathurst winner Mostert, also contemplating a move overseas, gave no guarantees of his future at Tickford, or in Supercars, after finishing second behind DJR Team Penske star Scott McLaughlin in Saturday's race one of the Darwin Triple Crown.
