I think there are 3 different aspects of front wheel alignment
Initially there are the two alignments which are set by the angles of the frame front in the chassis, so in theory not really adjustable BUT the post 2008 system does allow a very small amount of adjustment of the camber
So there is castor. This used to be 2 Deg , but is now 4 (from memory) and is the inclination of the king pin (in a fore and aft plane)
Then follows camber. This can be anything from 2 Deg negative , neutral , or 2 degrees positive. (this is measured at 90 deg to fore and aft) Use whatever is in the handbook.
Lastly there is toe-in/out this is adjusted by the track rod ends. This can be set to owners preference, BUT use the handbook figure as starting point.
Some leeway is permissible but try to get the reading the same on each side.
