The Ford teams say that they have a very narrow set-up window, with rake and yaw significantly impacting the race speed of the cars and the ability to look after the rear tyres.

'description' => 'The Supercars Championship, currently known as the Repco Supercars Championship, is the premier motorsport category in Australasia and one of Australia\'s biggest sports. It originated from the Australian Touring Car Championship (ATCC), which held its first race in 1960 at Gnoo-Blas in Orange, New South Wales. The ATCC evolved over the years, and in 1997, it was rebranded as the V8 Supercars Championship, eventually becoming the Supercars Championship we know today.
Some of the leading drivers in the history of the Supercars Championship include Peter Brock, who is often referred to as the "King of the Mountain" for his nine victories at the Bathurst 1000, a race that is considered one of the biggest in the series. Other notable drivers include Dick Johnson, Marcos Ambrose, Craig Lowndes, Shane van Gisbergen, Jamie Whincup, who holds the record for the most championship titles, and Mark Skaife, who has also been a dominant force in the series.
The Bathurst 1000, held at Mount Panorama Circuit in Bathurst, New South Wales, is arguably the most famous race in the Supercars calendar. Other significant races include the Sandown 500 and the Adelaide 500, which are known for their challenging circuits and thrilling competitions.
The Supercars Championship has grown to become a globally recognized series, known for its competitive racing and passionate fan base. It continues to be a major part of Australia\'s motorsport culture, attracting top drivers and teams from around the world.',
