Thanks Eric - You just saved me 35k$
Planned to exchance the 200 QT 20V with a 100 S4 94.
I understand your conclusion - the rear anti-roll bar is not important on
the type 44.
Mounting a stiffer front roll-bar and a upper brace would be better -
or springs and schocks without lowering the car?

The reason for my looking for a rear roll bar, is for better slalom,
and I thought, that the S4 (not your new one, gratulation) with stiffer
springs and
rear anti-roll bar would be an improvement?

Kind regards Claus Vegener
