Just thought I'd bring it up for a reason: it works! Well, Phantom grip does work - a little. It's not great for the diff, it doesn't perform as well a Torsen or Quaife, and it doesn't work to replace a blown diff or strengthen the stock diff. It's not worth the money, don't think I'm a proponent, but previous threads were too harsh: it is a real LSD when you are done, but it's effectively a cheap clutch-type, not a great Torsen.
