A little piece of Porsche racing history was made over the weekend (4/5 September) when two different Carrera Cup competitions ran in the same country. While the Porsche Carrera Cup GB had a pair of races at Knockhill, the Carrera Cup Germany was in action at Brands Hatch as a support race to the DTM.The global Carrera Cup concept runs in seven countries or regions, with championships in Asia, Germany, France, Great Britain, Italy, Japan and Scandinavia. The Carrera Cup GB was established in 2003 and is a leading support race to the MSA British Touring Car Championship.With 23 cars at Knockhill and 17 racing at Brands Hatch, a total of 40 911 GT3 Cup cars raced in Britain on Sunday.At Brands Hatch, British racer Nick Tandy used his local knowledge to win and close the gap to championship leader Nicolas Armindo to just seven points with two races to run.Meanwhile, at Knockhill there was a win apiece for Tim Harvey and Michael Caine as the points' gap between these two long-established rivals reduced to 27 points with four races left to run.The Carrera Cup GB continues at Donington Park on 18/19 September for rounds 17 and 18 of the 20-race season.
