Thanks, guys. I appreciate the positive comments. Encouraged by such reasonable behavio(u)r, last night I finally bit on front strut tower braces (for both the Z and my 330xi). I'll report out my experience in a related thread. The balanced discussions here helped me to finally go ahead. I figure with cars 12 and 13 years old, I could benefit from tightening up the front ends. Although I don't race on a track, I have to admit that the winding roads in my area bring out some spirited driving. I would wager that I am not the only one.
