The 911 GT3 with the Manthey Performance Kit was able to unleash its full potential on the Nürburgring Nordschleife, the traditional test laboratory for sports cars at Porsche. With Porsche works driver Kévin Estre at the wheel, the modified GT sports car ripped round the 20.8-kilometre course in Germany’s Eifel region in 6:55.737 – 4.19 seconds faster than the standard 911 GT3 did a year earlier. Both vehicles were equipped with the optional Michelin Pilot Sport Cup 2 R tyres. The lap time was certified by a notary who was present on site.
