Grimmspeed claims in slalom tests, their strut tower bar reduced strut tower deflection from 0.18-inch to 0.03-inch (http://www.grimmspeed.com/strut-tower-brace-brz-fr-s/). Whether or not that is true or exaggerated is not my point, just fyi.

The stiffness allows the suspension to do it's job, and chassis flex MAY lessen the effectiveness of the factory sway bar.

That said, unlike the Grimmspeed, the Cusco bar is hinged, so one can expect it to work slightly less effectively.

To the OP and supporters, you can say it feels stiffer and more responsive and you're likely correct. You can say it feels like it rolls less and I believe you to be honest. It does feel that way to you... but a strut tower bar doesn't directly serve that function.

Unless your sensitivity to body roll has a resolution of <0.15-inch or better. :respect:
