Anybody know if this is the same as the one in my '87 Quantum Syncro?
There is a picture of a chassis with the two green lights in the
positions of the center and rear differentials. At least I think they are
both green; the center diff one has not lit since I bought the car last April.
There is a single knob that you pull out halfway to lock the center diff,
and all the way to also lock the rear diff.
I don't think that it is because the diff is not really locking. I
presently have 195-60-14 Dunlops on the car, and the ones on the
back have worn way past useful in snow. With both diffs open, a bit too
much power in snow brings on lots of wheel-spin oversteer. Locking the
center diff makes that go away, presumably because it is difficult to spin
a rear tire without spinning a front one.
I am planning on making it through the summer on these Dunlops and getting
some sort of all-weather tires next Fall. Since this car has way more dry
grip than needed on the street (I can get my g-force fix in the Lotus) and
it snows here in the winter, I have been considering 175-70-14 tires.
These are the 14x6 GTI 14-spoke wheels.
