Hi explicit, I have the nizpro stage 2 on my F6 running a Tunehouse custom edit tune My ZF has done 35,000 km with the stage 2 kit still running the factory standard trans, I have changed over to the castrol transmax Z so far its holding together, though and it gets changed straight after every drag racing outing I think a 10 is achievable with the factory ZF......will have a crack when we get some cooler air
