Unless you have a Grp A rear beam or "slot" the mounting points, the rear is not adjustable. 1.5° negative camber all round and 0'20s toe-in.

Most places will try and get you to run the toe parrallel, as this is what Ford recommends. However, this doesn't tak into account the bush deflection you get with forward movement, so if you set it to parrallel when the car is static, it will toe-out on the move causing the inside edges of the tyres to wear. If you set to toe-in slightly when it is static, you will get parrallel then when the bushes deflect in forward motion. A bit of toe-in gives the car some stability anyway... .
