Nissan released a second video of the incredible 7:29 lap time achieved by the GT-R earlier this year at the Nürburgring Nordschleife along with a photo of the stock tires that were installed on the car at the time. It did so to dispel accusations that the time might not be 100% authentic. Porsche in particular seemed highly suspicious, and boldly claimed its belief that Nissan wasn't using stock tires at the time. The new video starts with some off-track buildup and shows the 50kg of test equipment that was on-board the car at the time, as well. Although we don't speak Japanese, we think that's what they're talking about along with discussing the fresh stock tires that were fitted to the car. The actual lap starts about 4 minutes in and looks pretty authentic to us. We're sure there will continue to be questions and complaints from all sides in this controversy, and we know that this is starting to turn into a a bit of a melodrama, but we really can't help ourselves. You can catch up on the whole sordid affair by clicking here and check out the video after the jump.
