Porsche 911 GT3 RS Spied On Nurburgring With New Manthey Kit And Giant Wing

The fact that Manthey Racing is working on a new package for the Porsche 911 GT3 RS isn’t a secret anymore. We saw a prototype testing around the Nurburgring earlier this month and today, a different test car makes an appearance around the famous track. This is a rather aggressive-looking machine and we have to admit it looks unstoppable attacking the ‘Ring’s corners.
