Is VLSD in Sport Package really useful ?

Umm.. am I reading this correctly? You guys are saying that the vlsd is only as good as the vlsd oil inside. Even if you change the oil for the vlsd, it is still toasted after 60k miles? This is because the vlsd and the oil in the pumpkin is separate from the vlsd? I have open my diff cover 2x. I never seen any separate oil inside. I'm no expert or anything like that but I'm 99% sure that changing the diff fluid is all that is needed to maintain the vlsd.

The VLSD fluid is silicone based. It it inside the ring gear carrier. Which is a sealed unit. There for separate from the gear lube. Changing the gear lube will have no effect on the silicone fluid in the ring gear carrier. The only way to change the silicone fluid is to get the whole ring gear carrier, because it is a factory sealed unit. So if you are going to do that. You should just go with an aftermarket LSD which is cheaper. Unless you find a factory VLSD on flea-bay. Most of these are toast to begin with. What happens is the silicone fluid breaks down over a period of time. Trackdays SPEED up the process. If you are into . It will break down quicker then say normal sane DD.
