Jason Bright's Team BOC Holden will wear a unique bonnet at Hidden Valley featuring the face of a competition winner.
An initiative of V8 Supercars wagering partner UBET, the winning fan has already been selected and will be revealed in Darwin on Thursday.
The UBET branding replaces the car's primary sponsor BOC on the bonnet for the one-off promotion.
Bright is the current qualifying and race lap record holder at the Darwin venue, although both are likely to be broken this year on the new surface.
The current records were set in 1999 (Stone Brothers Racing Ford) and 2002 (Holden Racing Team) respectively.
