I have strut bars on my RX-8, but not because I thought it would keep the shock towers in line. I saw it as a cheap way, like Mazdaspeed or AutoEXE undercarriage braces, to strengthen the car. Probably more snake oil then anything else as I've tracked with and without them and noticed no appreciable difference.
If you think you felt a difference in your RX-8, especially if it were driving on the street where you should be nowhere near the limits, I'd suggest placebo effect.
I think my point is no harm in getting them, but money would better be spent on tires and alignment, etc...than on that particular part. That, along with undercarriage braces, were last on my list.
a Bit? ummmm ok...
Placebo effect? ummm no....
