Cortina upright KPI/SAI wanted
Andy S - 8/1/07 at 05:03 PM

To save me having to strip and acurately measure one does anyone have the KPI/SAI detail for the Cortina upright - I have searched all over and all I can find is a figure of 4.8 - which seems low to me.

Cheers

Perhaps this will help - copied from elsewhera on the forum - can't remember where.

Nearly - its just that the essential dimensions for calculating the SAI are missing

So close.....

Thanks

Andrew

Stoppress - just looked again at the drawing and noted the 4 1/2 degree and little arrow which looks like the right dimension - Boy thats a shallow ange - and explains quite a bit - many thanks

For the completely thick (me) what are SAI & KPI ?

King pin inclination, and Stearing arm inclination. Ray

King Pin Inclination

Steering Angle Inclination

Both the same thing but the KPI is almost an historical reference from the days of solid front axles.

Angle through the ball joints of the upright when looking at the car head on.

And it has about half the KPI of what is required for good geometry.
