Thanks for all the responses...so it sounds like it's not the strut brace itself, but the entire package that actually makes the difference in handling. (I'm guessing the brembo package has an entirely different tune.)
Good to know, since I'm not really interested in a part that's just eye candy without making a real difference driving-wise.
