Well, on the front end typically it is the same amount front and rear. So 2.5mm would be 2 1/2 shims behind the roll center balls where the hingepins go.
If he was running arm sweep it would have been noted as there are 2 different spots for the amount of shims on the front end.
The rear end just depends on the amount of Toe-in he is running. If he is running 2 deg of rear toe then he has two 1mm shims behind the roll blocks.
