Does the standard GT strut tower brace need improving/replacing?
One of the things that surprises me a bit about our new 2015 GT Premium convertible is the cowl shake. Our pavement here is less than ideal, and the rear view mirror constantly is shaking and blurring, along with the upper corners of the windshield moving enough to see. It is worse with the top down, of course.
The standard Ford strut tower brace for the GT looks to be plenty substantial -- is there an additional brace that triangulates with the firewall and adds enough stiffness to improve the convertible's lack of stiffness? Is the Ford Racing strut brace and cowl brace worth the $$'s?
I am interested specifically to hear from those with 'verts, but thanks in advance for any suggestions.
