Hello,
Yeah its possible to change it.
The big question is: do you wanna change .cam files from a mod or do you wanna change the current simbin .cam files?
Mod cam files are much easier as they are not coded. As for the files from simbin theirselfs its a more complicated story, and i like to reffer you to Nogripracing.com (here you find all the info on how to extract the files!)
If this is not the case. let me know what you want to change in veiw perspective. So i can tell you how to do it. (only for Mods)
