Does anyone know the KPI of cortina uprights?

Has anyone actually measured it?

A detailed drawing someone posted on here shows it as between 4 and 4.5 degrees

Nominal angle from Ford is 4°48', and surprisingly the applied castor is only 1°40' +-45'! - the weight must have a big bearing on the self centring

This is from a bigger GIF I've got... 4 1/4 degrees if I read it correctly?

So not too bad then.

Depends on who you ask I think.

I've read that something around 10degs is optimal (Des Hamill's book) so that's what I'll be aiming for.

As I understand it though (and I don't profess to being anywhere near to knowing it all) you can compensate for the lack of KPI of the 'tina parts in some areas by adjusting other measurements.
