You can adjust the cameras.ini file in the cars data folder if it has one, can be a bit difficult to position them though.
I think so...the onboard, bumper, and bonnet cameras can be adjusted in the car.ini, not sure about the two chase cams though.
In game there is a cameras app, I think you need to enable developer apps, with which you can edit F6 cameras. You need PP filters on for that Gesendet von meinem ZTE BLADE A512 mit Tapatalk
