This brace is for the 05+ mustang GT w/o the plenum cover. (See our double barrel high clearance brace for plenum cover and supercharged cars) Besides being the best looking brace out there its also the most rigid and lightweight. We use a 1.25” O.D. chromoly tube which is tig welded to boxed structure on each end which are also tig welded. These boxes use all four bolts on the strut tower to mount the brace solidly( no heim joints to pivot). One look at one of these braces and you will see the design, fit, welds, and finish are second to none. They come in a black powdercoat and install time is less than 15 minutes.
