From outside experience, I would suggest to not trust the adaptor (i.e. Phantom) kind if your car is going to be under heavy, stressful driving or high WHP goal. I have seen them either shred the gears or crack under load or both. But everyone's experience and preference is different and respected, of course.
I installed a Quaife in my last car and I loved it though it was a FWD application which is best suited for. With the 240, from my research, I'm eyeing the KAAZ or Cusco and probably 2 way for my ultimate goal in the future.
Best of luck on your decision.
