Used parts of Supercars appear to be a favourite collectible with fans, with one owning a side skirt from Scott McLaughlin’s Volvo (year not disclosed), a door from James Moffat’s 2016 Volvo and a rear corner from Nick Percat’s Commodore.
Another fan has a Dunlop tyre from Whincup's 2009 championship winning Triple Eight Falcon, complete with the 123-time race winner's signature and marks from a celebratory burnout.
Another collection features the door of the Jason Bright's Brad Jones Racing Commodore from the 2014 Sandown 500, that was run over by Rick Kelly.

Perhaps consider getting Lowndes' signature tattooed on your arm like this mega-fan.

Refuelling of a different sort is important for Supercars fans.
