Here is small update for Monza circuit.
Special thanks to TTM75 and Ryder. Without PSSG editor this wouldn't be possible to do.
I changed some advertising banners in the Curva del Serraglio, Variante Ascari and Curva Parabolica.
Back up your original files ...
If you like it, I finished circuits Austin, Hungaroring and Silverstone for you.
