A new upgrade kit for the Porsche 911 GT3 RS is being developed by Manthey-Racing. A recent spy video shows the test vehicle pushing its limits on the iconic Nurburgring race track.

At first glance, the Manthey-tuned 911 GT3 RS may not appear visually different from the standard model. However, Manthey has a track record of focusing on enhancing the car’s aerodynamics and chassis in their previous upgrades.
