Looks awesome!
Incase anyone is having problems bringing up the menu using Reshade 4.x and above:
Go to your Project Cars 2 folder, then open the 'reshade.ini' file there.
Add the following:
[INPUT]
KeyScreenshot=44,0,0,0
InputProcessing=2
KeyWireframe=0,0,0,0
KeyEffects=0,0,0,0
KeyReload=0,0,0,0
KeyMenu=113,0,1,0
Next time the game is opened you will be able to bring up the menu using Shift+F2 and finish the configuration like the author of the mod described.
