MGTF Rear caster

  Newish member here, I'm using the front and rear uprights from an MG TF for some custom suspension. I cant seem to find what the rear caster angle is on the upright as understandably on the actual car its fixed. So if anyone could get their MG TF and find out that would be immensely appreciated.

So what is the project your using these on?........curios minds need to know!
If your avatar is anything to go by.......a Ferrari P4 replica?

Thanks Cobb’s, I knew I could rely on you to ask, I was too polite & reserved to enquire.

Unfortunately the suspension settings thread doesnt quite have exactly what i need, i had a look at this post before but only the front castor is mentioned because i believe the rear is non adjustable hence there is no data. I realised I also didnt provide a method for finding this angle, but essentially an easy way I can reverse engineer it is to get the angle shown in the picture (5 deg is an example)

Ah its a completely bespoke car, its pretty much in its infancy, when its a bit more mature i might show a bit more. My profile picture is a custom exterior design i did a year back or so just for fun, heavily influenced by the p4 as correctly guessed!
