Perhaps you can source some used in the usa and have them sent to the shop for machining and upgrades?
Out of curiosity are you running an lsd? I have a wavetrac lsd for sale that would definitely help minimise wheel hop which is a contributing factor for what kills the diff and half shafts etc
Have a squiz at these:
those DSS ones + an LSD and the defiv lockdown kit + M3 rear subframe bushings would be everything possible available on the market right now that would minimse hop/snapped axles. the DSS shafts are built for some sorta ridiculous WHP/torque levels.
