Reigning Bathurst champ Chaz Mostert has gone from contesting the 1000 with a racing veteran in Paul Morris, to a young up-and-comer in Cameron Waters, who leads the V8 Supercars development category, the Dunlop Series.
But what many don't realise is that Waters, 21, has actually raced more Supercheap Auto Bathurst 1000s than Mostert.
Waters holds the record for youngest Bathurst starter, his first opportunity coming when he was 17. However this year is the first-time he's been paired with a bona fide Championship contender in Mostert, who sits 198 points away from leader and teammate Mark Winterbottom in the standings.
At next week's event, Waters will juggle his own Championship campaign in the Dunlop Series, as well as the main event.
Mostert has every confidence in his young co-driver to get the job done on the track. If they are successful next weekend, the pair will smash the record for the youngest winners at Australia's biggest motor race, eclipsing that set by Craig Lowndes and Greg Murphy, who won for the Holden Racing Team when they were 22 and 24 respectively.
"Cam's done more Bathurst 1000s than me!" Mostert said on last night's edition of Inside Supercars.
"He knows the job he has to do, he's in the Dunlop Series up there as well so I think by the time he gets to the race he will probably have more miles around there than I will have."
While Waters admits there is some pressure racing with the defending champion, he's thrilled to have been charged the responsibility after pairing with Jack Perkins last year and running well.
"Yeah, there is pressure there, but you've got to look at the other side - I am with the best team at the moment, Chaz is driving the car really well ... so that makes my job easier," Waters told v8supercars.com.au.
"I can just lob in, do a good clean job, give it back to Chaz in one piece and hopefully it looks after itself."
He believes the pair has a real shot at going back to back and scoring Prodrive's third consecutive win at Mount Panorama.
"Chaz is obviously going real well at the moment so we've got a real shot of winning it," Waters said.
"I'm really excited - I've got to shake this flu before I get up there, and hopefully have a good showing in the Dunlop Series as well."
Waters has his own Championship to fight for in the Dunlop Series, and with a 173-point lead over last year's champ Paul Dumbrell (who he will race in the main race as Jamie Whincup's co-driver) the title could be clinched at the Mountain. The race winner is allocated 300 points, rather than having 150 points split over two races like usual rounds.
Waters tested his Dunlop Series car on Monday ahead of the mini-enduro at Bathurst, and also shook down the wild card FG X Simona De Silvestro and Renee Gracie would take to the Mountain.
There has been talk of a possible step up for Waters next year, though the musical chairs of movements is still to play out.
For the young driver, it's about concentrating on his driving and achieving his goals, which include clinching the Dunlop Series crown after he fell short last year.
"There's no point getting caught up in talk of next year - I may as well keep focusing on what I'm doing make sure I have a good showing," Waters said
"If I have a good showing at Bathurst I can nearly win the [Dunlop Series] championship I think at Bathurst, so we'll wait and see."
After finishing second with Mostert at the Wilson Security Sandown 500, the boys should be considered one of the favourites for next week's big race.
