Front Uprights
Hi All,
Please advise if the Granrda 93 has the same front uprights as a sierra.
Thanks in advance.

Nope, geometry is different.

Yup, geometry is completly different. As is the stud pattern, 5 stud, not 4.

not wanting to confuse anybody, but are you sure????
I thought they were the same except for the outer flange, which is obviously 5 stud instead of 4.

I thought they were the same too.Obviously the actualy hub's are different in 4 or 5 stud flavours. The shock diameter might be larger (i.e same
size as 4x4) compared to sierra 2wd so the top hats would have to be larger diameter.
Granny 4x4's are definately the same as thier sierra xr4x4 counterparts along with using the same TCA's etc.

I have been informed that apparently the granadas all use the 4x4 dia strut mounting and the 4x4 pinchbolt setup for the bottom balljoint, so just as
you suspected Mr G!

That's what I have been led to believe. I don't have any personal experience as I'm using cortina items which are better all
round.

What's wrong with the Sierra geometry?

The sierra geometry is pretty poor for double wishbone suspension, as it was designed for McPhearson strut.
The sierra uprights are also pretty damn heavy and ugly compared to the cortina ones.
There have been threads before on the difference in geometries of the uprights. Do a search, I'm sure something will turn up.

I realise the Sierra strut stub doesn't really lend itself to double wishbone suspension, but I thought the "mushroom overcame the
problem.

the mushroom allows it to be mounted but the upper pivot is well inboard of where it would ideally be if you use sierra front uprights with standard
"book" chassis geometry.

Couldn't you just make the mushroom to fit with the hole further out to suit where you want it?

Sierra upright with an offset insert allows more KPI -- the Cortina part dosen't really have enough KPI for a light car

Why should a light car want more KPI?
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

KPI and caster go together, normally cars with a large caster angle have a large kpi normally caster is about 3 degrees more than KPI.
KPI also has quite a large a self centring action even when stationary.

Does the KPI affect the camber change on compression in roll?

In itself no -- but if nothing else on the chassis is changed on a double wishbone balljoint suspension the top wishbone will be shorter.

That's
why I asked for clarification in my initial response to phelpsa. His dismisal of the Sierra "upright" seemed illinformed.
Cheers, Rorty.

Ok, maybe i'm wrong. I was just assuming that as the cortina upright was designed for double wishbone it was more suitable.

But it was designed for a car he weight of a 3 litre Granada Estate, as a general rule the more weight on the front wheels less caster and kpi is used
--- remember also the base Granada (aka Consul) didn't have power steering but it did have wheels & tyres that were pretty wide for the
early 1970s so Ford designers had to do everything possible to reduce the steering effort.

I know nothing about kpi and caster so thats probably why I made that assumption.
