Here is maybe a more constructive thought. I believe that Audi's decision
to add tower braces to their later cars must have been economic. It must
have been cheaper to add the tower brace than to beef up the tower to a
comperable stiffness. If so, without the factory tower brace the towers in
these cars would flap in the breeze. But my original point stands, stiff
towers are less that half of an optimum solution.
I can not defend apparently less than optimum (dumb) decisions, be they
Audi's or my own.
