I agree Bill. This is a geared limited slip as well unlike the ZF LSD that came from the factory in my G50/50. There are pros and cons of both, but you certainly won't ever have the clutch chatter that sometimes is experienced with the ZF. And, the clutches can need to be replaced. I have put this on my watch list because, for various reasons, there is a chance that I may keep the G50 01 that is in the car at this moment and an LSD would be a very nice addition.
