Possible to fix this issue with virtual mirror?

I have been getting rear-ended by AI so want to be able to see/anticipate/react when AI get too close to me or are going to rear-end me but my virtual mirror cuts them off as show in the below video. Shift + seat controls don't seem to work. I also tried a few changes to Rearview Height in .plr file but didn't look like that was the issue although I didn't try every possible value and I also noticed that there are other review mirror lines in .plr file and also the mirror seems to also need to be zoomed in more, etc. etc. but I just don't want to spend all night fiddling with this. Can someone at least get me started with how to be able to see the car behind up until they would make contact with me and also to get zoom correct? Many thanks in advance...

 

Sorry just realized I never posted the video. NO wonder no responses and I keep forgetting to make video while at the track and now struggling with stupid shadowplay.

Anyway, what I need to be able to do is point the virtual rear view down a bit because cars getting cutoff at the bottom when they get close to me and also I need to zoom out in a bit.

Google told me about a lot of .plr settings for rF1 but AMS seems to have much fewer settings? Or hidden in different file? Or some keyboard mapping I can't find to adjust virtual mirror? I am using cockpit view.

I don't mind doing the work I'm just stuck.

TIA
