Rear Stabilizer Bar

[Michael Pederson]

I've noticed that some of the VW aftermarket kits for the Passats etc. are
running what looks to be a fairly (at least vis-à-vis the 1992 UrS4 17mm
RSB) "heavy" rear stabilizer - 24mm or 25mm bar.  I'm not sure about the
length of the VW bar's "leverage" point, but I would doubt that it could be
longer than the UrS4/67's

Actually, understeer is corrected at the rear axle, especially if it's a
front-driver.  I race an ITC Scirocco, and am running one big bar in the
rear, and NO bar in the front.  The car used to push like mad, until, at the
advice of about the entire field, I removed the front sway bar.  Some
fwd'ers are using TWO rear bars.  Also, no top strut tie bar is used,
although that's due to rules constraints.

Essentially, it's the car's tendency to "fall over itself" that lets the
front bite.  Although I haven't taken the time to try to comprehend the
higher physics of it, I can tell you it's much faster that way (2-3
seconds).  It seems that by reducing sway in the rear, it bites less, and
has more of a tendency to float around toward the front.  I suppose an
ultra-stiff suspension helps matters too.

>Not worth the Trouble.  Type 44 understeer needs to be conquered at
theFRONT of the car.  Stiffen the front so that it doesn't fall over on
it'sself and the car is much more neutral.
