Re: sway bars counterpoint
"Scrub" is not really that much of a problem. I was
concerned at first about this, but it just doesn't
seem to metter that much (IMFO). The only time scrub can
even be felt is when the start has a very sharp turn
into the timer. When you get a setup like this you
can feel the scrub because you are still going very
slowly and turning very sharp at the same time. Once
you get rolling the scrub effect pretty much disappears
even in the sharpest of corners. This might bother other
drivers more that me, you know, those "precision" types
I tend to drive with a "rally-type" style, using power
and the locked diffs to toss the rear end around and
eliminate the otherwise inherent understeer of the driven
front wheels. Running with locked diffs also creates a
very effective if primitive form of ABS. You lock one
wheel, you gottah lock at least three. It's real hard
to lock three wheels.
Locking the rear diff seems to be the most critical, so
I usually just lock 'em both. This seems to work equally
well with the Turbo Coupe and the 4000 Quattro. I think
the effect is more noticable with the 4000Q due to the
additional body roll and the much smaller sneakers,
205-55-14 on 6" wheels vs 215-50-15 on 8" wheels, even
though the TQC has almost 2x HP. It could also be due to
much more seat time in the 4000Q, perhaps 10+ auto-xs
vs only 4x in the TQC, and the TQC auto-xs were like
2-3 years ago too, memory fading and all.
I've got my Winter Beater (Tm) '84 4000Q setup so that
I can lock just the center diff, or just the rear diff.
Rear diff only is definitely the HOT SETUP for rally-
style hang-the-rear-out-at-WFO-style turns. *EXCELLENT*
in the snow and ice where these cars have so much #$%@#!#
traction that they can actually be boring. :)
Rear diff only locked + snow = boring !NOT!
Please try to keep all this good stuff of the auto-x
mailing list for obvious reasons. This is for fellow
Quattro enthusiasts ONLY.
