    Review & Installation Video

    Review & Install Video

    Hey guys, Stephanie with americanmuscle.com here with an overview of the KONI STR.T Shock & Strut Kit for 2011 to 2014 GT, V6, and Boss Mustangs. In this video, we're gonna over a few topics when it comes to this shock and strut kit. We're gonna talk about the benefits of this kit, the performance you can expect from the kit, and we're also gonna talk about the install as well. I'll get into more detail with the install later, but I can tell you right now that the install for this is going to be a two out of three wrenches in the difficulty meter. The KONI STR.T Shock & Strut Kit is gonna be for the S197 owners out there that are looking for entry-level performance from a nonadjustable shock and strut setup. This kit would be a good option for you if you're looking for an OE replacement, or they can complement a set of lowering springs, or if you're looking for a smaller upgrade and you're on a budget. Now, I say that about lower springs because, usually, when you lower your car with set of springs, you also shop for shocks and struts. If you run your stock shocks and struts with lowering springs, they'll not only wear out the shocks and struts faster, but you also won't get the most performance or the best ride quality from the springs. Shocks and struts like the STR.Ts here are more capable of working better with a lowering spring because they're designed to work with a firmer spring rate and lowered ride height. So it's nice that this kit'll work in both cases, whether you're just looking for a stock upgrade replacement, or you're looking for something that'll work with lowering springs. These are considered the entry-level kit. These are the KONI Orange, which is one step below the KONI Sports or the KONI Yellows. Even though this is an entry-level kit, you are still getting a bump in performance over your stock components. Now, while these are performance oriented, you aren't getting the most performance-based kit with these here, either. These are nonadjustable, as opposed to an adjustable option that you have. That means that they have a fixed damping rate, and these have a standard twin tube gas pressure design and a steel body. But like I said, these are still upgrades over the factory shocks and struts. When it comes to price, you're looking at spending just south of $500 for this kit. Now if you're just looking for a basic set of shocks and struts and you're really on a budget, there are some other options on the site that are even less expensive, but just know that the KONIs here have been around for decades, so they're tested, proven, and reliable. The install here is gonna be your normal shock and strut install that should take about four hours to complete. I'm gonna call this a two out of three wrenches on the scale. You need a spring compressor and a lift would help you out here as well, but the job can be done with a jack and jack stands. You're gonna need to get down to the spring strut assemblies, so everything like the wheels, the brakes, the ABS lines will need to be moved out of the way so you can pull the assemblies out of the car. A spring compressor will help you remove the spring from the strut and install the new front struts, which install the same way that the factory struts came out. The install's the same for both sides. The rear is where things are a little bit different, but it's nothing crazy here. Just like the front, the rear springs and shocks install the same way that they were uninstalled. No surprises here. Once that's done, you can bolt everything back up and you're ready to go. Wrapping things up here with the KONI STR.T Shock & Strut Kit. This is KONI's entry-level kit, but it's still gonna offer performance benefits over the factory components. This can work as a factory upgrade replacement, or it'll work with a set of lowering springs to give you better handling performance. You can check this kit out more online for yourself, and for all things Mustang, keep it right here at americanmuscle.com.

    Superior Suspension. Improve overall ride handling and road hold while minimizing bounce and body roll with the KONI STR.T Shock and Strut Kit. The set includes four quality KONI components, two front struts and two rear shocks, that have been completed in a classic orange finish. Together they deliver a noticeable upgrade to your 2011-2014 Mustang's suspension system with consistently reliable performance.

    Bang for the Buck. The KONI STR.T Shock and Strut Kit is considered an entry-level performance kit, which means it's an excellent choice for the value-conscious driver. If you're looking to replace older OE parts with a quality set that offers an upgraded sense of road hold, safety, comfort and stability, look no further. It's all here.

      You may need an extra pair of strut mounts handy

      Everything installed with no issues with the product. Just had a strut mount come apart during transition, but was able to get it back together seemingly issue-free with some luck. Paired them with the Eibach Pro Springs which really stiffened up the ride quite a bit while dropping it about another inch from factory Performance Pack springs.

      Night and day difference

      The body roll on my 13 GT was really bad stock. It drove like a boat. With the koni socks and struts the body roll was all but eliminated. When you turn the wheel the car responds , when you hit the gas there is no more squat you just launch forward and same for nose dive during hard braking. Solid investment!

      Great Product

      I purchased these shocks and struts for my '12 GT and paired them with HandR Super Sport Lowering Springs. I thought I was going to lose a good amount of ride quality; I did not. The car rides great and handles really well. I am very happy with these. They took about 5-6 hours to install with one mechanic and a few knowledgeable helpers.

      Decent

      Rear shocks went in easy enough (2 bolts, 1 in trunk, 1 underneath). Torquing the trunk bolt is a pain, might need crows feet. Also be sure to torque at ride height otherwise you can damage the bushings (which are already fragile compared to stock ones). Front struts are a pain because of trying to torque the replacement lock nut. (DO NOT USE THE STOCK TOP NUT - THE THREADING DOESN'T MATCH). Didn't include any instructions or values, so I used Ford OEM recommended values. My stock suspension was leaking everywhere, and now it's a lot more responsive and stiff.

      So glad I got the Koni orange struts and shocks. Car feels more planted to the streets and freeways as I drive. Handling improved a great deal. For an improvement over you stock struts and shocks these are worth the money. My daily driver is very happy car! Should got them a long time ago. Shop installed in just under 3 hours. Springs, Struts, and Shocks.

      Daily driver

      if you are looking for a quality replacement shock and strut, then these should be on your list. If you are looking for an upgrade, I would choose a different one. These might technically be an upgrade, but I wouldn't say a big change in handling characteristics were felt. I have these with the eibach lowering springs and daily drive this car.

      Handles the Dragon quite well.

      Everyone bleeds the yellow Konis but these actually performed beyond what I thought they could. Me and my brother took our Stangs to Tail of the Dragon and literally slaughtered that beast! He has a 15' S550 and I have 14' S197 and he could not lose me in the turns. Then I took the lead and he had to push his S550 to keep up. I am beyond happy with these and I'm glad I went this route.

      Installation Time: Weekend

      May 08, 2017

      Nice, trickier install than expected

      A friend and I installed the full set of Koni STR.T shocks and struts in my '11 Mustang GT convertible over the course of a weekend. I had been unhappy with the stock damping-- the car floated and bounced on the highway, squatted and dove accelerating and braking, and swayed and wobbled alarmingly when cornering. With the large tires and relatively soft springs the grip level was actually pretty high, I'm sure, but I was never comfortable using it since it always *felt* so unstable. Performance: With the Koni STR.Ts installed the difference is obvious. First the downside-- on rough pavement at lower speeds, you will definitely notice that it rides harder. The soft stock setup could absorb this kind of situation and yield a smooth ride. With the STR.Ts it's definitely firmer and you'll feel the bumps. It's not bad at all, plenty of cars are this firm stock, but there is a difference. The good part of the ride quality comes at higher speed, particularly on the highway. The increased energy being imparted to the springs at higher speeds was just too much for the stock dampers to tame, leading to the bouncing and heaving that was driving me crazy. It's a night and day difference with these new ones-- driving an asphalt highway onto a concrete overpass where the pavement is at different heights, there's now just a fwup fwup and hardly any body movement, whereas stock it pitched and bobbed up and down like a pogo stick with a blown shock. *Huge* improvement in ride quality here. Likewise dips in the road on fast two lanes are now handled smoothly without the deep body motions of the stock suspension. Finally handling; I doubt the limits are really much if any different than before, but because the car is more stable and feels more planted, I now feel like I can come closer to them. This is a street setup anyway; I was never on the limit and don't plan to go there now. But it makes brisk 8/10 driving much more pleasurable and confidence inspiring. So all in all, a definite improvement in enjoyment, although I can't attest to what if anything it would do in terms of a skidpad or lap times. Installation: So no doubt the pros and old hands will laugh at me here. I'm not much of a mechanic. I can change my oil and spark plugs, but I had never tackled a job like this before. Youtube install videos made it look reasonably straightforward though, and a much more experienced friend agreed to help out, so I decided to tackle it. The first gotcha we encountered was removing the shocks. If you just turn the nut on the top of the shock mount, it simply spins the shaft inside the shock. The top of the shaft has flat sides, so you need to use those to hold it still. It proved easier said than done, however. Even a 6mm wrench (smallest I had) was a bit too big. Vice grips kept letting go. Eventually we went out and bought the biggest strongest set of vice grips we could find, and that did the trick. Most of the videos showed using an impact wrench, which might have made it easy to remove, but my car being a convertible has very little room above the shock mounts (the well for the top when it's folded down intrudes) so the impact wouldn't fit. Retightening this nut once the new shocks were in was also difficult. You are supposed to torque them to a specific setting, but putting a socket on the nut covers the flat sides on the shaft, so once again the shaft just spins and the nut doesn't tighten. We had to get a crow-foot socket for the torque wrench so that the top of the shaft would not be obstructed and we could get the vice grips on it. The bottom of the shocks was pretty straightforward removing the bolt with an impact and tightening with the torque wrench. The next surprise was on the struts at the front. The brake line is held to the back of the strut with a bracket and what is essentially a large screw. The hole for this on the factory strut is threaded, so there is no nut. But the Koni was not threaded, and so the bolt wouldn't go in. We had to run out and buy a tap to make our own threads (8mmx1.25 is the size you need) which worked fine. I was very surprised by this oversight though, and this is why I'm dinging it one star for "Fit". The nut holding down the top of the strut gave us the same issue as the one on the shock-- turning it just spins the whole rod that the nut threads onto. We eventually managed to hold this in place somewhat using a strap wrench. This was not enough to hold it when slowly turning it with a torque wrench, but it did provide enough resistance to tighten it with an impact. The factory service manual gives a torque spec for this nut, but in all the howto videos they just go at it with an impact, so we did the same. Maybe I'm just uptight, but the fact that we couldn't be sure of the torque here left me a bit uneasy, but it seems to be fine. Only other thing to be aware of is that the Koni's come with a different size nut for the top of the strut. This was under a protective plastic cap and we almost discarded it as just part of the shipping protection. But the original Ford nut won't thread on, so we realized we had to use the new one here. I'm sure someone more experienced would have an easier time, and we did eventually get it done, but it took a full weekend, including a lot of time running around to parts stores looking for things that we hadn't known we would need. All in all I'm happy with the result. The installation is certainly doable if you know what you're doing, and even if you don't, but don't expect it to be a cake walk in the latter case. Recommended.
