Nope. The Brace you are thinking of is the oem Ford brace that came on all 05-12 verts. It also became oem on 07-12 coupes after that. That brace..that ford called .."a lower control arm brace" actually just ties the rear of the oem K frame together.

The oem ford brace uses 2 bolts at each end, with all 4 x bolts in the horizontal plane.
The brace that GMS is selling (also sold by both BMR)
http://www.bmrsuspension.com/?page=products&productid=138 and also Steeda ) steeda's version is called a ..'G-trac', actually does tie the A arms together. It resides in parallel, and just a few inches in front
of the ford.. "lower control arm brace". The GMS / BMR / Steeda A arm brace sits just aft of the oil pan plug.
And yes, the damned thing does work, only takes a few minutes to install. With both braces in there, everything is rock solid. The BMR version / steeda / GMS brace uses a single bolt on each end... with both bolts in the vertical plane. The BMR version has a slight bend in the DOM tubing. The steeda G-trac version is made from chromolly steel
