[s-cars] EDL fails (but my new 22's worked great!)

[LL - NY]

Lost signal to my satellite link so I was unable to return posts to
my previous start to this thread. Several lister's asked what tires
I had when I got stuck, they are (if you believe tires.com) "Viking" 
H-rated snows, supposedly made by Continental, which I bought
in sort of an emergency on an emergency budget, size 205/55-16 
'cuz thats the smallest that would fit. That said, I still agree with
Taka, I think comparatively, EDL was the cheap way out of providing
us with a switch and the corresponding wiring, for a locking rear
diff. I still think I would've had little trouble with my 200 up that same
hill, although due to the diff in tires, it would not be an apples to apples
comparo.

As for my 4KQ, it would've plowed right up the hill with both diffs locked,
but the tires are comparatively tiny (185/65-14) AND it probably would've
killed the Kamei front spoiler the P.O. had installed on the car.....

LL - NY (missing the old 4KQ right now)
