To clarify, you mean increase or decrease bar if front washes out?  I'd
have taken that as decrease, but other comments make me think you might
be suggesting increasing its size... Which, in and of itself, may
improve grip by keeping the wheels more firmly planted, but will also
*enhance* the car's tendency to push.  That's when, in support of Jack
and Jeremy's comments, is when spacers will do more than bigger bar.

Interestingly, I have found that tendency has as much to do with a rear
bar's mounting position and hardware as it does size.  After changing
style and mounting postion on the scirocco's rear bar (and making no
other changes), I went from a few inches of inside tire lift to a few
millimeters (in a certain situation).

However, as you're referring to, when the rear wheels are driven, it's
different story entirely, and twist is more pronounced (ala 911 in an
autocross).   I wonder if Audi's removal of the rear bar from the urS
cars post-'92 was safety driven or performance driven.

Truer words never spoken.  Trying to make an inherently understeering
car into an oversteering one is a fool's errand, and anti-productive in
a good rain race!   And on my street V8, a more realistic goal would be
front-to-neutral, rather than too far the other way...

Anyway, carry on.
