Opps, front strut bar question.

I have my front strut bar currently removed. To maintain front end stiffness, would I be able to upgrade the front sway bar and add a front tie brace (http://www.importpartspro.com/gtfrlotiebrf.html)? Or swap to the stillen bar and call it a day?

 

Run the Stillen tie bar, the stiffness is needed up top.

 

I guess I kind of figured the lower tie brace acts as basically the same thing as the strut bar. What does the lower tie brace do?

 

Nothing on this car, the front cradle is really stiff. The upper body is not as stiff, reason for the brace
