Girlfriend got her car tracked today, after getting new tyres, after other ones got scrubbed out due to tracking, car still seems to pull to left slightly, just wondered if anyone know what the correct settings should be, got this print out just doesn't look right to me.

Unsure of the settings mate and I'm no mechanic so couldn't answer for definite in regards to the printout above.
What I do know and what I have experienced on my own car is the Fiesta ST "characteristic" is to pull slightly to the left with the fall of the road as with most other cars.
Also if you have maintained the P-Zero's on the car from the factory and replaced like for like then the Pirelli's are well known for tramlining.

Front toe in should be 1.1mm total +/-1.2mm
Rear toe in should be 3.6mm total +/-4.8mm
Hell of a tolerance there !!!!
Rear toe is all on one side (not correct - and not adjustable) causing the thrust angle - that may well be why it pulls one way

Fiesta ST's are notorious for wearing the edges of the front tyres out, not uncommon for them to come in for their first service and the inner edges be completely bald.

Sorry can't really answer that. Assuming all is straight i.e. no accident damage. Depends on how the rear stubs are fixed, if they bolt on then shims maybe an answer. Better speak to an expert in alignment.

Looking at the figures above the left rear wheel seems to have 3.1mm toe in and the right rear 0.3m toe out , would think this is causing a slight bit of the issue , but as mentioned above and from personal experience it will follow the camber to the left as most fords do . If you want to improve the rear tracking the only way to do it is move the mounts on the chassis for the rear beam to achieve a better balance

Taken my sons ST150 in today to have the alignment checked and adjusted, Guess what near side rear was 3.1mm toe in (wonder if they are all the same). Had to use a shim behind the hub to adjust, couldn't get it a perfect match to the off side but did set rear to 2.4mm total toe in and reduce the thrust angle vitually 0.
