So its like a powertrax for Honda? I thought I heard a rumor that all Honda trans are LSD from the factory once...guess that was wrong. Kinda nice but even at a $115 its a waste of money unless you are doing any racing with your economy trans. LSD will actually get you in more trouble in bad weather due to the both wheels slipping and leading you into a ditch. With an open diff, the car is basically a tripod so you have 3 anchor wheels and 1 driven so when the 1 starts to slip, the other 3 keep you in control.

The comment about the spare tire is moot because a spare tire should never be used to replace a driven wheel. If the front blows out, move the rear forward and put the spare on the back (for a front wheel drive car obviously). I assume Subaru makes their spares to tolerate being a driven wheel but most spares are not recommended for use on driven axles. I also realize that almost everyone ignores this little safety tid-bit but I felt it should be restated anyway.
