Review & Install Video
Hey, guys. Adam here with americanmuscle.com. Today, I'm bringing you a detailed overview and installation of the KONI Sport Adjustable Shock, Strut, and Eibach Pro-Kit Lowering Spring Kit which will be available for all 2011 to 2014 GT, V6, and BOSS 302s.
So in this video, of course, I'll be going over all the details you need to know about the KONI Sport Adjustable Shocks and Struts as well as the Eibach Pro-Kit Lowering Spring Kit. Now, there's a lot of details to cover in this video simply because this is an absolutely huge upgrade for your suspension on your late S197. Now, for the shocks and struts, I'll be going over the ride quality you can expect with them installed as well as their materials and construction. For the Eibach Springs, I'll be detailing the specs, all you need to know about the drop for your particular model from the GT, V6, and BOSS 302 as well as the performance and handling benefits of adding these to your ride as well. I'll top the video off with the install which I'll let you know upfront here will get two out of three wrenches on a difficulty meter because it is a little bit more involved than a direct bolt on but it's not gonna be the hardest job in the world.
The KONI Sport Adjustable Shock, Strut, and Eibach Pro-Kit Lowering Spring Kit will be for any 2011 to 2014 GT, V6, or BOSS 302 owner who's looking to seriously improve and upgrade their suspension and handling package for their late S197. This will involve the ability to adjust and fine tune their shocks and struts while getting an aggressive appearance with a pretty noticeable drop in ride height, anywhere between an inch and an inch and a half on a progressive lowering spring.
So obviously, there is a lot to talk about in this video so I'm gonna break it down piece by piece like I said in the beginning. I'm gonna start with the KONI Sport Adjustable Shocks and Struts since they will play a huge part in the handling, performance, and the ride quality of your S197. The KONI Sport Adjustable Shocks and Struts, otherwise known as the KONI yellows, are just one step up from the KONI orange STRTs, which you might recognize from the site, but of course, these will give you a full range of adjustability on your shocks and struts depending on your personal feel so you can change exactly how the ride will feel that day.
Now, with that said, it all comes down to personal preference, again, but you can loosen or stiffen the dampening with just a simple turn of the knob. A clockwise turn on the knob will loosen the compression and rebound ratio and of course, just a counterclockwise will stiffen it back up.
So these are actually gonna be constructed from KONI out of a gas-pressurized twin-tube design here with a larger diameter piston for optimum street performance, and of course, track as well.
Now, they wouldn't be the KONI brand name without that yellow finish and a KONI logo printed right on the side here. Now, the twin-tube gas-pressurized design, I just mentioned a second ago, is going to be found with a lot of options in this price range but KONI has been making variations of the shock and strut for literally decades now so they've built a pretty well-known name, and that's a name that I even use on my own Cobra so I can tell you firsthand this comes with a very comfortable ride, and of course, it can really take a beating.
Now, obviously, there's a lot of goodies that go into this package. So the KONI shocks and struts you see here with all the adjustabilities I just mentioned are obviously gonna be best suited for a set of lowering springs. Now, you can save yourself the hassle by picking up this particular kit because they're grouped perfectly with the Eibach Pro-Kit Lowering Spring Set so you don't have to go shopping around finding for the best match because it's already done for you.
Eibach Pro-Kit Lowering Springs will work perfectly in conjunction with your KONI sport adjustable shocks and struts to drastically improve the handling performance and ride quality of your Mustang.
Now, when you lower the center of gravity on your Mustang, not only are you getting an aggressive muscle car stance but you're also gonna reduce squatting during acceleration, hard body roll while hitting the corners, and of course, nosedive or excessive nosedive in those hard-braking situations.
Now, with that said, this is gonna be perfect for those daily drivers, track queens, or even those weekend warriors. Now, this offers a lot of different drops in ride height for the different models of the '11 to '14 Mustangs so bear with me a second while I get you the specifics.
Now, if you're rocking a GT from the '11 to '14 family, whether it's a Coup or Convertible, expect a 1-inch drop in the front and a 1.5-inch drop in the rear. If you've got a BOSS 302 of the same generation, expect a 0.6-inch drop in the front and a 1-inch drop in the rear and finally, if you've got a V6, whether it's a Couple or Convertible, expect a 0.8-inch drop in the front and a 1.2-inch drop in the rear.
Now, the drops I just mentioned will be sitting on a progressive spring rate from Eibach which is gonna be perfect for the daily driver, the daily commute, or the guys out there hitting the track on occasion, taking those hard turns or hard cornering.
Now, with that said, the progressive spring rate is gonna be acting pretty normal and very comfortable under normal driving conditions but once you put a little bit more pressure on them taking it to the track or hitting those hard turns, they're gonna stiffen up and react to those cornering situations.
Now, as far as the pricing goes, if you're interested in the KONI Sport Adjustable Shocks and Struts and you're looking for a perfect Eibach combination, you can pick up this particular kit for about $850 and in that region. Now, it doesn't save you too much money from picking them up separately but it'll save you enough to make it worth it.
Now, in my personal opinion, the main purpose of this entire kit here is just, honestly, convenience. That way if you're picking up these shocks and struts and you're looking for the perfect lowering spring, you don't have to go through digging, swapping through page by page to find what fits perfectly. The Eibach kit and the KONI's have come together for the perfect kit and they work together really well as our customers have definitely confirmed. If you wanna check that out for yourself, we've got some customer reviews and testimonials sitting on the product page of the KONI and Eibach kit so you can check those out for confirmation of that fact.
Shifting gears over to the install portion of the video. Like I said in the very beginning, this isn't gonna be the hardest job in the world but it is a lot more involved than a direct bolt on so it will require some mechanical know-how and experience. Now, if you don't have that, of course, there's no shame handing this one over to the professional to get done properly. Now, if you are tackling this yourself, you wanna make sure you have the proper tools on hand such as a jack and jack stand or a lift if you have that, making it a lot more convenient. You wanna make sure you have a ratchet and full socket set on deck as well as a spring compressor to safely remove and install the springs.
Overall, this should take you about four hours if you're doing it yourself and it gets the two out of three wrenches on our difficulty meter. So just to give you a brief idea of what exactly you're gonna be working with, you're gonna, of course, wanna jack up the car and support it on jack stands or get it on a lift if you have access to one. Now, you're gonna start by removing one wheel at a time in the front and, of course, you're gonna have to drop the entire breaking system out of the way just to gain access to that factory strut.
So once you have that all taken care of, you'll pop open the hood and remove the nut holding your strut in place at the top of the strut tower while supporting it from the bottom. Move down to the bottom here and remove the lower strut bolt as well as the N-links and pull the entire factory strut assembly out of the vehicle and set it aside.
At this point, you'll need to use your spring compressor to install the Eibach Pro-Kit Springs onto your KONI yellows. Once you have that back in the vehicle, you can start by tightening everything down at the top of the strut tower to 30 foot-pounds and, of course, the lower strut bolts and the N-links to about 85 foot-pounds.
So once you have the fronts taken care of, the rears will kick off the exact same way. You'll remove the rear wheel, drop the entire brake assembly out of the way just to gain access to that shock. Now, the top nut on the shock will actually be located in your trunk so you'll have to move over that trunk liner on the sides and bottom to gain access to that. The lowers might be interfering with the rear sway bars so you might have to drop that out of the way to gain access to that.
Now, with that said, at this point, you wanna make sure you're supporting the rear differential housing before you remove any of these nuts. So once you get that top one taken care of, you can start lowering the jack, supporting your differential housing out of the way just to slip down that shock and spring. Once you've unbolted that rear shock and slipped that lowering spring out by lowering the differential, you can start by reinstalling all the KONI adjustables and the Eibach Pro-Kits right in the reverse order and you can top it all off with the exact same torque specs as the fronts. After that, you're good to go.
Now, at this point, you wanna make sure you're driving around on the new suspension setup. Let it break in before you make any adjustments, of course. Now, typically, I'd recommend leaving it right in the middle as far as adjustability goes before you start your ride. Once you break everything in, you can determine how you'd wanna adjust things and, of course, clockwise loosens, counterclockwise stiffens, and you can use the adjustability tool that Eibach and KONI have provided for you in the kit.
Now, on top of that, about four hours' worth of time in the driveway at home, two out of three wrenches on our difficulty meter. Overall, not the hardest job in the world, again, but it is a lot more involved than just a direct bolt on.
So if you're the owner of a 2011 to 2014 GT, V6, or BOSS 302, you might be looking at a complete overhaul of your suspension and handling package in which case, check out the KONI Sport Adjustable Shock, Strut, and Eibach Pro-Kit Lowering Spring Kit which can be found right here at americanmuscle.com.
