      Hi AM, I was given this rear brace as a gift. I noticed no hardware. Do you just use the hardware that is there? Top bolt take off apply brace, apply two top nuts! Is this correct or am I right for a change? Thanks Ed.

          No welding needed!

          This is a quality made strut bar welds are good and looks good too. After researching and finding that you dont need to weld it on i was pretty happy, slapped this on and rolled out u can feel a slight difference in turning but its not significant youll need more upgrades. You can hear it slightly back there doing its job but remmember your making things more ridgid which in turn makes more noise. It took me about 20 min to install (i took my time) but i had shop tools.

          Very good choice

          I am stationed in Alaska and I'm the the Air Force. I keep my car stored in my hometown in CT. I went home on leave for three weeks and i wanted to order something for the car but didn't want to spend to much since i only drive it once every couple years. I bought this bar and installed it in 5 minutes with my air compressor and air gun. The difference it made to my car was great, it doesn't slide all over the place when you are spinning the tires in 1st and 2nd gear. it handles so much better around corners. I love it so much i ordered the front one the next day!

          Nice suspension addition

          I installed this part in my apartment parking lot with minimal effort and a couple of hand tools. Welding is not necessary in my opinion as I just bolted it on. The rear end of the car feels tighter and I can tell a slight difference in cornering. I previously installed the Ford Racing front and rear sway bars and the Steeda rear shock tower brace helps bring it all together. The shock tower brace reduces noise and seems to supplement the new rear sway bar performance. I would definitely recommend this product to anyone looking to add some additional stability to their suspension/chassis.

          Great product for the novice who wants to improve Mustang handling. Watch out for the Shaker 1000 series radios though. Product will not fit with the Shaker in the car. It is a great addition to the front shock tower brace.

          Works as expected

          Definately can feel a difference in the rear end in regards to handeling. Just over feels more solid and fun to drive around corners....of course the front is still heavy and not very neutral but its still a front engine rear drive car and handles awesome....also added eibach sway bars, eibach lowering springs and about to install subframe connectors to complete my suspensions.

          Easy install, good performance.

          First off, you do NOT need to weld this brace in. It it very much overkill, this was confirmed by my trusted service advisor at Ford, Steeda, and American Muscle. (Welding also tends to void certain parts of your vehicle warranty. Yes, I know about the Magnuson–Moss Warranty Act, however welding in a part is a very big grey area in relation to warranty. In addition to that, it also is hard to remove said item once it has been welded in....) (If you do choose to weld this brace on, remove all items from the area to be welded, clean up the area to be welded, and REMOVE YOUR CAR BATTERY TERMINAL CONNECTIONS. ) To install this piece, you must remove the carpeting from the trunk of your car. Before you literally take the carpeting out, you can easily just pull back the carpet material covering the the shock towers and also the spare tire well. Once tucked safely away from the strut tower, you must grab yourself two wrenches. One large wrench and then a small crescent wrench. It doesn't hurt to grab some WD-40 or another penetrating oil or lubricant. Spray said lubrication onto both shock tower bolts, and allow it to sit and penetrate for a few moments. Once soaked in, place the large wrench on the nut that is holding your shocks, then place the small wrench on the very top of the bolt. Holding the bolt and stopping it from spinning, use your large wrench to loosen the bolt on the shock tower. Once significantly loosened you can put the small wrench down and use solely the large wrench to finish removing the bolt. At this point you can grab yourself a large socket wrench and continue removing the bolt, however using the plain wrench from before is just as easy. With the bolts removed, grab the brace and twist one end and extend the brace a bit. Extended, take your brace and lay it over the shock tower bolts, be sure that the brackets match with the sheet metal of the shock tower. The open end of the bracket should face towards the front of the car, while the closed off end should face towards the rear of the car. Now, check how the brace fits between the towers, to extend or retract the brace simply take it off the shock bolts and turn one of the brackets clockwise or counterclockwise. At this point you should just eyeball how wide it should be in relation to the shock towers. You want the brackets to come as close as possible to touching the body of the car on the left and right sides of their respective towers. Once this is accomplished simply get your brace to lay flat, to do this you just have to press down on the brace bar itself. The bolts keeping the brace flat should be loose from the factory, but if they are not simply loosen the two big Allen wrench bolts up a bit. Now all that remains is to re install the shock bolts onto the tower. Doing this is just a reverse operation of the removal process. You may not need to use the small wrench as much however. After all the bolts are nice and tight holding the bracket, be sure to tighten the bolts which allow the bracket to be extended or retracted. They are just two nuts on each side of the metal brace itself. With everything tightened and installed, press down on the brace and try to move it. If it is rock hard and feels solid you installed it correctly. If not, tighten the bolts just a bit further. Be careful not to over tighten the shock bolts, this can lead to breaking or snapping of the bolts and this is a very expensive and non warrantied mistake. Finally, push the carpeting back into its original position, you may choose to use a razor blade and cut notches into the side carpeting to allow it to fit over the brace, however unless you are a neat freak or perfectionist this is not necessary. Congratulations, you are now finished installing your rear shock tower brace, go out and test it out! Be sure to come back here and write a quick review about it, and share how cool this dual purpose modification is.

          rear shock tower brace and front strut tower brace

          Both braces have improved the Pony's handling, especially around turns. Body "dipping" or body flex has almost entirely been eliminated; although the ride is a little stiffer. Good value for the results. Highly recommend the installation of both braces without getting into expensive anti-sway bars.

          Rear Shock Tower Brace

          Well made product that easily adjusts to fit between shock towers. Instructions say it should be welded and bolted in place but I just adjusted length to fit tight and bolted it down without welding. I also installed a front shock tower brace which is bolted on so the welding seems to be overkill. With both braces installed you will definitely feel an improvement in handling with less sway in the car on turns.

          An eye opener

          I bought this last summer from AM...and just got around to installing it today. I took the car down to the speed shop in town where they custom fabricate race car chassis's, winged sprint cars, stock cars, etc. They do loads of tig-mig and Aluminum welding all day long...and were extrenely busy..for the upcoming season. The intitial fit was not quite there on my 2010 GT auto. Both mounting brackets were not quite flush with the body of the car, where they surround the rear shock mounts. No big deal, just some creative bending to get them flush. I had them tig welded, since tig welding is strong, and also results in zero sparks, etc. The trunk mat is 1st removed... which takes 6 secs. The side carpeting-liner is simply rolled back out of the way. We had some minor difficulty getting one of the nuts off with the impact gun. I have Roush shocks, and they also have 2 x flats at the very top of the threaded stud. It comes apart easily, using 2 x small wrenchs. Once tig welding completed, and my tour of their superb shop was complete... the neg terminal of the battery was re-connected. Then I drove home. Before I got 400' down their gravel driveway, I knew something felt different. With 29 K miles on the car, change anything, even subtle, and I feel it. Once on the main road, it was a 6 mile ride home. The back end sorta feels... tighter, or stiffer. It's like the back end is now solidified. The sheet metal on these cars is NOT thick per the race car fabricators at the shop. It's a LOT thinner gauge than I thought. I think what's happening is the flex and twisting and any side to side loading has been minimized a bit. The front end still needs work though. I have a BMR A frame brace to still install + a steeda FRONT strut brace. Steeda does indeed make a Front STB that will fit over a Roush M90 or TVS blower (with inlet tube on drivers side)and still be easily able to close the oem hood! So yes, it does make a difference, not huge, but enough that I could immediately tell something felt different. I'm surprised the car stays together, after seeing all that thin sheet metal. It also explains why it could easily flex, twist, etc.

          Yes, it does work.

          High quality construction. Fit & Finish is good. I got the Steeda rear shock tower brace installed and welded at a local muffler shop. You'll definitely need an impact gun to take off the flange nuts on the OEM shocks to install the brace. As Rob noted on his review, the brace does stiffen up the rear from chassis flex. I also installed a front strut tower brace I got from AM. I noticed that my 2011 Mustang GT is quieter inside the cabin and overall ride feels "tighter" around corners with this combo because of less chassis flex.

          Delivery was fast as usual. The brace definatley stiffens up the rear and makes my car handle way better, especially with the strut tower brace on the front as well. took it to a garage to have it installed as i dont really know much about welding. Took 30min for them to install it.
