Manthey-Kit Porsche GT3 RS Nails a Fast Nürburgring Run, but Mustang Still Leads

The Manthey Kit-equipped Porsche 911 GT3 RS posted a 6:45.389 Nürburgring lap, nearly four seconds faster than the stock car and driven by Jörg Bergmeister, but it still trails the Ford Mustang GTD Competition’s 6:40.835. Manthey’s aero upgrades, revised suspension and brakes, plus optional Cup 2 R tires boost downforce by about 20% with less drag, enabling higher speeds in fast sections of the track.
