Anyone using a phantom grip LSD?
Phantom Grips are a bad idea!!!
As everyone know, LSD makes it so that both wheels can turn to privide better traction. And the phantom Grips do that. But the way the do that is to completely bind your spider gears together. By doing this both wheels will spin together and the torque will be distributed to both wheels, which is good for stright line acceleration. The problem is that, unlike a true LSD, both wheels must spin at the same rate ALL THE TIME with the Phantom Grip due to this. This is a problem when you make a turn. As you are turning (part of a circle) each wheel is a different distance form the center axis. Therefore, the out side will has to travel a greater distance than the inside tire in the same amount of time. So, the outside wheel needs to spin faster than the inside wheel. But the Phantom Grip prohibits that. This causes a lot of extra stress on your front end. It will definately cause your tires to wearout prematurely. Hopefully it won't break anything. But I definately think it will eventually cause your front end to fatigue as well. I'm willing to bet that you would feel something binding up or trying to hold your care back when you are creeping through a tight turn.
However, I have no experience with the Phantom Grip, and I do not know anyone that has one. But the theory doesn't sound very good (unless you only have to drive in straight lines). I, personally, would not get one and would not recommend it. If you are going to go through the time, effort, and money to rebuild a tranny, I suggest you do it right and get a true LSD.

2 pieces of ALUM bar stock machined = $50
4 tiny springs = $1.98
Paper clips to hold assembly together during install = $.001
The look on everyones faces when it blows up = PRICELESS!
The thing is, with a redesign a PG can be made to work. But OPM had the design WAAAAYYYY before PG ever came out.
OPM has some clutch material, PG has none. Metal parts floating in oil = almost no friction. If it did have any friction, your motor would only run about 4-5 minutes instead of 200,000 miles.
