Well, since I am basing my impressions on just this one car, I will give a little of its history; which may (or may not) be pertinent. The previous (long term) owner was female... although I generally dislike gender generalizations, I do believe that men are more apt to thrash on their cars.
Also, at some point the nose has been replaced on my car, which may have stiffened things back up.
My 2002 experience is limited to just this one car, which I have only owned for 6+ years... so it is quite limited.
My brain has a hard time telling the difference in some before/after comparisons. If the change is not immediate, I tend to forget/not notice.
I was testing mine while preparing to install a stock air cleaner, which the brace would not clear.
So, I was hoping I would not see a difference. These things are somewhat subjective.
As I mentioned, I did try to measure movement; but my test drive was typical of what I'd put the car through... not a thorough flogging.
I like the idea of sways first and brace later. Incremental improvements will let you appreciate the changes each modification makes.
