Dont't know if this has been said yet, but Tim Cindric's son, 16-year old Austin Cindric, is driving for Erebus in the Bathurst 12hr.
Before you say, "Wrong Thread!", I've got a theory, maybe Penske is doing this as a way to get Austin some laps at Bathurst for a possible Wildcard entry for the Bathurst 1000. It isn't far-fetched as DJR-Penske has stated it's interested in a Wildcard entry for Bathurst. And maybe Austin could just be a contender for a co-drive with Ambrose, as well.
Another interesting bit to make this a reality is that last year, Austin Cindric drive in a test day for a Dunlop Series team and apparently enjoyed it. A lot.
Just a theory...
