Yes, I know how to install one.

From my perspective it will make a large difference, but that's also considering my driving style. I would suspect you would also find it to be extremely beneficial. Many on this site would not, and have no need for the time or expense of installing a limited slip spool or Phantom Grip.

In snow you just lightly apply the brakes and all your slipping problems disappear. You don't need a limited slip for snow. You need a limited slip for when you are at some kind of speed where you can't apply some braking to get the effect you need.

A classic trick in RWD vehicles with open differentials is to apply the parking brake a couple of clicks - not enough to kill it, but enough to act like a clutch type LSD, and drive out of the snow/sand/slippery condition causing one wheel to slip mercilessly. You can do the same trick with your FWD by very lightly applying the brakes.

There's a fundamental incompatibility with gear type LSDs and transaxles. Gear type LSDs want an EP additive. Your synchros do not want it at all. You have to decide which is better, being able to shift or preserving the service life of your LSD.

It isn't possible to provide a special lubricant for the Quaife unit since the gearbox and spool are in the same oil bath, so all you can do is run a good quality GL-4 lubricant and expect your spool will not last as long as it could if it were in GL-5 lubricant.

Here's what Quaife says about lubricants:

Quaife says GL-4 is adequate, so it will have a decent service life. No one can guess what the PG service life will be. Don't run GL-5, you don't need it and there is no advantage to GL-5 in a transaxle that specifies GL-4 as adequate.
