LB, RMC recommend the following:
Rear camber: 1/4 to 3/4 degrees positive
Rear toe: 0 degrees
Front camber: 1/4 to 3/4 degrees positive
front Caster: 3 degrees
Toe: 1/8"
However, as has been discussed elsewhere the Jag suspension in use under under the cobra needs some attention.
Some time back, when Mike Moyland still owned RMC, his chief engineer ( Jaime) advised me the following is a much better start point. ( with the series 11 RMC, twin vertical side rails) and tune from the following for personal preferance.
Rear Camber: 0 -1/4 degrees negative
Rear toe: 1/16 - 1/8"
Front ( this lot may not apply except to the series 11)
Toe: 1/8"
Camber: 3 degrees negative
Caster: 5 - 7 degrees
With the series 11, Jaime recommended the front top arms be relocated to remove all anti-dive by flattening them to horizontal. To do this the front mount bolt was moved to be horizontal with the rear bolt and both bolts moved towards the back of the car by 1/2".
This meant that an extension has to be welded to the top mounting plate and the rear section of this plate re-inforced by adding a backing plate.
In short, the top a-arms end up horizontal to the road and are 1/2 further back.
This does many things not limited to the following:
Allows more caster, makes the steering a bit heavier in car parks but improves straight line tracking on the highway.
Causes the steering to self center better, and allows the driver more feel of what the front is doing.
Allows for negative camber adjustment to the front suspension. Much better handling.
Removed some of the anti-dive which allows more weight transfer during braking.
Slightly moved both top arms inwards removing some of the bump steer.
The above, when used together with a spacer between the steering rack and
its mount( lowering the steering rack) will allow almost all bump steer to be removed.
With regard to the back end. Scotty (Ozvenom) makes a mod to the rear lower arm to allow easy toe adjustment.
Hope all that helps.
Cheers
