    Review & Installation Video

    Review & Install Video

    Now, the Eibach Sport-Plus Suspension Kit that we have in this video should appeal to any S197 owner out there, looking to drastically change both the appearance and handling performance of his or her ride. Using a couple of key components from one of the most trusted names in aftermarket suspension. This does include a set of front rear adjustable sway bars, a set of dampers, and the very popular sportline springs, which will give your coupe or convertible a very aggressive drop.As far as bracing is concerned, you're gonna be looking at right around $1,100 for the Sport-Plus Suspension Kit, making it one of the most affordable currently on this site that does toss in some dampers. Installation will be two out of three wrenches on the difficulty meter from me, but we will have a little bit more detail on that later on.But let's first start with the drop because this kit will certainly cater to those S197 owners out there who prefer more of that slam look, and thanks largely in part to the sportline springs which are included here. They are a very popular spring by themselves. Check out the product page, read up on some of the reviews, check out the costumer submitted images and you'll get a better idea of what I'm talking about.Now, if this really isn't your bag, you don't like the slam look, you prefer maybe a more mild drop, then may I recommend checking out the Pro-Plus Suspension Kit instead. Essentially, the same exact thing you see in here but it's gonna swap out your sportline springs for the Pro-Kit springs and offer a less aggressive drop. But let's hang out on those sportline springs a little longer here guys, because in my opinion it is one of the most important factors with this kit as we are talking about that bigger drop and it continues to make them the popular choice we keep talking about for, not only the S197, but also other generations as well.Let's break down that drop specifically here guys, with the sportlines in your S197 and you're gonna be looking at one and a half inches upfront and a whopping two inches for the rear. That's a pretty big drop guys, in fact, one of the biggest ones you can currently get for your S197 in the category. So, long story short, if you wanna go low, the sportlines continue to be the spring of choice.Getting a little further into the sportline springs, you're gonna find that progressive spring rate and that's something I always like to see on a street car because it's gonna give you the best of both worlds. It's giving you that softer initial spring rate, making things a little bit more comfortable while cruising, but then these guys tend to firm up progressively as they get compressed. So, you're gonna get a little bit more performance when these things are really pushed hard, and the spring rates are gonna reflect that.Specifically, you're looking at an initial spring rate of 183 pounds for the front spring and a pretty big range for the rear guys, 103 pounds is your initial spring rate, all the way down to 217 pounds once it is compressed. And this is just gonna help kind of give you what I talked about earlier, that softer, comfortable ride while cruising and then help firm up once you push these things hard in turns onto that secondary rate. And this will help improve your roll control overall according to Eibach when you use with those sway bars, which we'll talk about a lit bit more in a minute.Now, along with that improve roll control, you're also gonna be looking at less nose dive under hard braking and less squawk under heavy acceleration, and just general improvement all around. The car should just feel a little tighter and a little bit more responsive with the springs installed. And then, of course, there's one of the biggest benefits of the sportline springs and that is just general improvement to your appearance. Again, if you're a big fan of that slam or low look, the sportlines will never disappoint. One thing to keep in mind though guys, because you're getting that big drop in the rear, again, 2 inches back there, you can expect more of a leveled look with your Mustang, as opposed to keeping that drop 1.5 inches on all 4 corners maintaining the slightest bit of that nose down rates. So, something to consider there.Ultimately, I always encourage you to check out some customer submitted images to get a better idea of how your ride might sit with these springs installed. One thing I do enjoy about this particular kit is that Eibach has included their Pro-Damper shocks and struts. The reality is if you throw the sportline springs and that big aggressive drop on some high mileage factory dampers, it's just gonna be a recipe for a bad time, poor ride quality and ultimately poor performance as well. Eibach recognized this and decided to toss in these two dampers for this particular kit. At the end of the day, the Pro-Damper shocks and struts are just better suited to handle the added stresses of an aftermarket lowering spring, that lower ride height and the firmer spring rate that might otherwise tax your factory dampers a little faster. And ultimately, it's just gonna improve your ride quality and the handling performance along with the springs and sway bars.But I do want to point out that the Pro-Damper shocks and struts are not adjustable, meaning you can't soften or stiffen them up depending on your preference. Now, if that's something you had to have with a handling package like this, then my recommendation to you would be check out the Ford performance adjustable handling pack as they do offer adjustable shocks and struts. But the springs and dampers are only two-thirds of the equation here gang, as you can see, we're missing, or we haven't talked about yet, Eibach's adjustable front and rear sway bars which are also included in the Sport-Plus Suspension Kit.Specifically, you're looking at a tubular 36 millimeter front bar and a solid 25 millimeter rear bar. And again, guys, just a huge improvement over the factory sway bars in many ways. Now, the tubular option upfront will be nice because it will help save some weight compared to this big heavy solid options but without really compromising any rigidity.Now, as an S197 owner and as someone who has driven a bunch of these things in stock and modified form, my general feeling is that they are a tad underbarred from the factory. Meaning, you get that understeer and that push or plow feeling through the turns, adding a set of sway bars like this will drastically improve the handling and the overall feel of the car. It's gonna help turn in responsiveness, the car should feel a little bit more flatter in the turn and you can actually dial in a little bit of oversteer as well, helping the car rotate through the turn, something that really isn't present in factory form.Both the front and rear sway bars are three-way adjustable and this is one of those things that I encourage you guys, you're gonna have to play with it on your own time before landing on your ideal settings. Now, I'm sure some guys, like your Vaughn Gittin Jr.'s out there, prefer a little bit more oversteer where as other driving styles might prefer more of a neutral balance. So again, just play with the settings a little bit before landing on your optimal setting, is my recommendation to you.Another recommendation, start with the middle hole on both bars, getting set up for the very first time that would be the best bet, and then just kinda go from there. Now, if you wanted to soften the bar essentially you go from the hole farthest away from the bar itself or if you wanted to tighten things up a little bit, you go to the hole closest to the bar itself. So, my piece of advice for you there guys, when setting these things up for the very first time.Now, as far as construction for these sway bars, well, cold-formed high strength steel is what you're gonna be looking at here guys, aircraft grade of course, finished off in this red powder coat which will just help reduce any corrosion and also look pretty cool underneath the car when installed. I will say the Eibach kit does come with a lot of extras including bump stops, rear sway bar links but it does not include front sway bar and links, and that is something I would recommend picking up especially with the sportline springs in place, having a set of adjustables to adjust them accordingly, will certainly be a great idea. Let's talk about that installation briefly, guys, and I had this one pegged at a two out of three wrenches on the difficulty meter at the top of this video. Not necessarily because this work is difficult per say, there's just gonna be a lot of steps involved installing the springs and sway bars and so on.Again, two out of three wrenches on the difficulty meter, maybe a few hours from start to finish, less or more depending on your expertise and your setup. As far as tool list, well, basic socket set is going to be the biggy in addition to a few open-ended wrenches, definitely gonna need your spring compressor for this install as well guys, don't forget that. And last but not least, a lift or Jack and Jack Stands should help you get the job done.Wrapping things up, the Eibach Sport-Plus Suspension Kit will offer a huge bang for your buck. The improvement handling performance alone will certainly be worth the price of admission, the factor in that awesome ride height, thanks to the sportline springs, and you got a can't miss turnkey package for any S197 owner out there. So, that is my review of the Eibach kit which you can grab right here at

        Can I run 305/35R19 tires on the rear with this kit with out rubbing?

        I have a '14 Mustang V6 Coupe with BBK long tube headers installed. The bottom joint of the headers sit maybe 1/4 to 1/2 inch below the subframe. Will the drop of the Sportline springs be too much for my car?

        • The Eibach Sport-System-Plus Suspension Kit will be a nice size drop and will work with the headers. However, if you live in an area with many potholes or speed bumps then you may want to look into a lighter drop.

        Adjustable height?

        • This Eibach Sport-System-Plus Suspension Kit uses upgrades shocks/struts but are not adjustable. If you are needed a suspension upgrade in which will be adjustable, you will want to consider a set of coilovers or air suspension.

            No more drag slicks

            Great kit easy instal, quality, and performance lowered the car more than expected. Most spring manufactures over rate their spring lowering not eibach it was right on the money. I may go with their drag springs so I can put a taller tire and my rear slicks back on.

            Low we will go!!!

            Kit was an easy install, and lowered the car significantly. Handling improved immensely - the car sticks like glue now and looks great with my 35 series 20" tires. Only issue is I think I went too low. I'm dragging on speed bumps and the odd driveway onto the street, so I'll probably be getting a little taller springs. Its really hard to look cool when that dragging noise coming from the bottom of the car. For a Track this is an awesome solution.
