Whincup set for Phillip Island triumph History is in the making at Phillip Island this weekend but V8 Supercars champion-in-waiting Jamie Whincup insists it's just another meet. The Red Bull Racing phenomenon is on the brink of a fourth successive championship, leading the field by more than 400 points with two meets to go. Success would make Whincup just the second driver in Supercars/Touring cars history to win four straight titles, after hall-of-famer Ian Geoghegan. With just 600 points to play for, Whincup barely needs to avoid DNFs to claim the crown, and his slice of history. But he says the comfortable margin belies the true nature of the season, which has included plenty of bumps for his Triple Eight team. Wind back the clock to the winter swing through Perth, Darwin and Queensland and Whincup was down and out. Whincup said his comeback from down the pecking order made this season different. "We certainly haven't been in a mid-season form slump before," he said. We were a good 200 points off the lead and really thinking 'Are we too far away to even claw back?' Win, lose or draw this year, I'm pretty proud of the turnaround everyone's made to get ourselves back into championship contention. The idea of the always-humble Whincup losing or drawing the title seems far-fetched. Supercars legend Dick Johnson told Sky Sports Radio it "would take an earthquake" to stop Whincup triumphing. In fact, the key question may not be whether Whincup claims the trophy on Phillip Island, but whether he does it on Saturday or Sunday. Whincup can effectively seal the title if he leads by more than 450 points on Saturday night. The required winning margin drops to 300 by the end of Sunday - meaning Winterbottom (402 points behind), Shane van Gisbergen (478 points), and Craig Lowndes (504 points) have some chasing to do. Either way, V8 Supercars officials will save the presentation until Sydney with the remote possibility of points deductions keeping the championship live. The prospect of a Phillip Island coronation doesn't faze Whincup, who said nothing would be different about the weekend's preparation. "The process is exactly the same as it normally is," he said. It's not like we can prepare any more ... we'll put everything on the line like we normally do. I've never focused on the result or the big picture. I've always focused on what I need to do to do a good job.
