Rear subframe inclination and caster angle
Hello
Nice to meet Cox owners on this Forum !
I am restoring a Méan Sonora built with a Mini engine. It could be the only one, out of 200 Sonora's, using a Mini engine.
For history of this car, please read

While doing so, I see there are many defects that I try to correct. The car was indeed built in a hurry, based on a chassis built for another engine, and using parts from a damaged Mini. The original Mini subframe was bent and repaired , and the Méan chassis was built around it ! I now use a new unbent subframe !
My question is about the vertical position or tilt of the subframe and the caster angle.
Because the subframe is at the rear, do I need to keep the Mini 3° caster angle ? Some people tell me it should stay like that. Others tell me the caster angle should be 0° at the rear. However, the car builder, Jacques Dheur, has modified the inclination of the subframe to make the coil springs of his suspension vertical. See picture 5958. This modifies the caster angle completely. And I do not know by how much because I have no information about the original position of the subframe in a Mini. What to do ? Original 3°caster, zero caster, or vertical columns ? What is the original position ?
I assume this problem must be solved by the Cox GTM users who also have the engine at the rear.
Can anyone help me ?
Your help and comments will be appreciated !
