afternoon Bob, the normal answer on here is that there are too many variables. So to start with are you CEC or BEC?
I copied this from an earlier thread - - - -
" Ride Height:
Front - 100mm (sump allowing)
Rear - 125mm
Camber:
Front - 1 to 1.5 degrees
Rear - 0.7 to 1.5 degrees
Toe Settings:
Front - 0.5 to 1.25 degrees toe in
Rear - 0.5 to 1 degrees toe in
The toe settings are actually very debatable. There are quite a few people who say that the toe settings should be toe out.
I feel that front toe settings in a toe out guise are more for the likes of westfields and other cars that run a Cortina upright or similar geometry.
The Sierra upright is inherantly good , but could do with a few tweaks, but as standard I reckon that the settings above would be a good starting
base...

Hi here is what some MKs have been set to to gain good grip on circuit.
Front. Start with 1.25-1.5 degs camber. if the car is softly sprung then try moving up to 1.75 deg this is to combat the front suspension going toward
positive in roll. At the front 0 toe just makes the car unstable. There is the option of either toe in or out but use one or the other. My preference
with the sierra upright is in. Try 1mm toe in or close too that.
One good thing to check or have checked will be you castor ideally you will want 5 deg MIN ussually more on a bec. Note this is not adjustable on the
indy but is good to know what you have to take into account when feeling what the car is doing on track.
Rear. At the back end it is customary to run a MIN of 1.5 deg of camber to combat the poor camber control in roll. But try as high as 2 deg to see if
improvements can be found. Toe is a little tricky as no real adjustment except for the shimming of the sierra part to the Mk upright. But go for 1-2
MM toe in. Also try to take into account the thrust alignment down the centre of the car as it's no use having good toe if its pointing to one
side or the other.
The above can be used as a starting point and then work from there to fine tune.
Cheers matt
