strut tower bracing?

[geezer stang]

a friend installed aftermarket sway bars on his 650(eibach adjustable),which did not come with a strut tower brace from the factory...i also saw a new "RTR" 650 without a brace,it would seem to me that bigger bars or stiffer springs could add even more flex to the strut tower area....or would it be the opposite effect,(less flex)?

The strut towers dont flex much on the s550 anyway. Chassis is prettt stiff.

As for if its every so slightly more or ever so slightly less, you will probably need to track down a structural engineer.
