This performance pack improves aero and decreases lap times. And it looks awesome. This is the Porsche 911 GT3 RS with a Manthey Kit fitted. For those who know, you know what this is all about.

Let’s start with the wheels, which get carbon fiber aero covers on ... the Manthey Kit provides roughly 2,200 pounds of maximum downforce. A regular GT3 RS makes about 500 less at speed.
