Didn't measure that, sorry.
Zero is the static ride height as I had the car set up to. I don't know if it was equivalent to standard, as I had 235/40 x17 tyres on, with the car set to a slightly "bum-up" stance.
FYI these measurements were taken on my Sapphire when Chris Woods set it up. He prefers static parrallel, as this gives a small amount of toe-out when moving forward. This makes the car a little nervous (and needs constant steering inputs), but it really did turn-in superbly.
On my Escort, I set the static toe to be in (0' 20"), as I didn't need the turn-in to be so aggressive with the shorter wheel-base.

Hey Mike
Managed to get round to fixing the adjustable TCAs, and the freshly refurbed 3 door hubs! All went together quite easily
I havent had chance to set up properly yet (what with there being no engine in the car).
So given that we are setting up for the nurburgring, I was going to set the Camber to 2 deg neg, but how about the track?

I havent put the adjustable rear beam on yet what with me having not bought it yet.

.Camber Angle

This should be set to -2 degrees (so negative camber from vertical of 2 degrees).
Toe In

What is this set to - presumably factory standard?
Castor Angle

No adjustment made to this...?
Leave the rear alone till I fund the rear beam
Cheers

Get the complete set with bushes and the holders for the bushes as its a different diameter and the holders are made a bit sturdier than the sapph ones.
All your diagrams are correct.
Toe is subjective - running it parrallel on a Cossie makes them "nervous" and prone to following every bump etc in the road.
I prefer a small amount of static toe-in (2mm front 3mm rear).
The only way to adjust the castor is eccentric top mounts or shimming the ARB. On my Escort I run 3° 30" as per the Grp A tarmac settings.
As I said, handling and preferred turn-in is subjective. You need to set the car up to YOUR driving style, which will require some experimentation.

I've got the complete front and rear suspension setup from nigel worswick's saph 4x4 rally car,which is basically 909 coilovers,tca's,tension struts,unknown roise jointed rear beam,rear diff cover with integral body mounting etc. all solid mounted.
This will be fitted to a saph or mk2 5 door,but with a ford v8.
Does the cars weight affect setup,as in ,the front end will be heavier than if a yb was in there.
Do any grp a settings apply on this setup? If so where do i get them from?
