The men stripped down to swimwear emblazoned with the Malaysian flag after the Australian driver's win.
The group - branded the "Budgie Nine" - have been held in a facility Kuala Lumpur since Sunday while being investigated for public indecency.
The men are expected to be charged when they appear in court on Thursday.
Malaysia has strict rules on any display of public indecency and foreign offenders are typically issued a fine before being deported.
