Just trying to figure out if the rear diff is an LSD unit. Normally there is a tag or the ratio and LSD star on the housing but i can't see any of these marks and was wondering if i could tell without pulling it apart...

pretty sure if its aus delivered, its a suretrac

All MY01 onwards WRXs and STi's have suretrac LSDs in the rear. The STi's also have a front LSD.

That being:
WRX 01->>>>>>>>> R160 Suretrac Rear, Open Front
STi 01->>04 >>>>>> R180 Suretrac Rear, SureTrac Front

STi 05->>>>>>>>>> R180 Mechanical Rear (Plated ?), Helical Front
