Tells you in the owners manual. It's 4.1l for box and 1.1l for rear diff.
If your Hawks a 05-06 it's uses a limited slip oil in the diff. If 07 it will take the the same gl5 spec oil as the gear box as it has a torsion type rear dif.

I've changed mine recently, car is an 07 and I used motul gear 300 ls for the rear diff. Is there that much of a difference?

Buy 4L for the gearbox and 1L for the diff.

Torsen type diff doesn't require a limited slip oil. But can't see any harm with it being in there.
If it was the other way round ie non ls oil in ls diff it would cause a problem.

Only difference being a limited slip diff needs friction modifiers in the oil to work properly, where as a torsen diff just needs a normal gear oil.

as above LSD oil will not cause any harm to a std diff so if in doubt use LSD oil...........

do not use in a synchro box however
