This is very interesting. I know porsche has been doing this for years, it was even black in the olden days.
Nice to see some kind of paint protection from the factory. And nice to see that the stance is that much more aggressive than the standard 3/4 that it needs this.
Does anyone know if this comes on the M3? When I test drove the M3 I did not notice this. It would be weird if the M3 didnt have it as the rear fenders are even wider than the 4.
