Yeah wanting something bulletproof. I am putting close to 500rwkw through it now but so far I've been looking after the trans with no hard launches, progressive on and off throttle etc, but I am looking to launch the car harder drag racing and I can see the input shaft snapping/twisting the moment I try launch it off the stall with slicks on. I do see a lot of the main players for ZF boxes in Australia are in Perth or Melbourne so maybe a road trip to Melbourne is on the cards or try buy a box outright from Perth and have it freighted over if I can't find someone local. I will look up XFT. Not a lot of options here in S.A. cheers
