Review & Install Video

Hey I’m Justin with, and I’m taking a closer look at eibach’s pro system plus suspension kit fitting all 2011 and newer Mustangs. Eibach is without a doubt one of the biggest and most trusted names in aftermarket suspension, outfitting everything from the most hardcore professional race team, to the Mustang sitting in your driveway. This kit is Eibach’s one stop shop for a more responsive, better handling car with an improved stance to top it all off. This kit doe include a few different components, so let’s break them all down. The pro system plus centers around Eibach’s pro kit springs and pro damper shocks and struts, these professional race springs lower the car a somewhat conservative 1” up front, and 1.5” in the rear. Of course when you lower the car, you’re lowering the center of gravity which will not only improve your handling, but it’s also going to help your stance as well by eliminating some of that wheel gap. If you’re looking for a more radical drop, then I suggest checking out Eibach’s sport system plus kit, which is especially the same kit I have here but offers a bigger drop thanks to different springs. The dampers do play a big role here as well because they are specifically matched to the pro kit springs, basically what this means is the dampers are valved or tuned to work better with the stiffer springs while still maintaining excellent ride quality. The second big player in the pro system is the addition of Eibach’s anti roll sway bar kit. This kit consists of the 3 way adjustable 36mm front bar, and a solid 25mm rear bar. You may or may not know, sway bars are without a doubt one of the biggest cause for reducing your body roll, and improving turn in response on your car, ultimately making your ride more predictable when pushed to the limits. Another nice thing with these sway bars is all the hardware that’s included, I mean we’re looking at high quality polyurethane bushings, with greasable fittings which is going to help reduce any squeaking, and ultimately prolong the life of the bushings themselves. Finally, they’ve provided nice solid Bullitt M links, which I will say are a huge improvement over your factory links. Since you are replacing a majority of your cars suspension, just be prepared to set aside a full Saturday or Sunday in the garage to tackle this install. Keep in mind, whenever you tweak this much of the suspension, you might end up throwing your alignment out of whack, so if you notice anything out of the ordinary in the test drive after the install, then don’t hesitate to give your local alignment shop a call, just to get everything checked out. So with this setup from Eibach, you can expect a huge change in your cars handling thanks to all the different components used with this kit. Kits like this are so great because they take all the guesswork out of trying to piece together different parts to improve your cars handling. So check out Eibach’s pro system plus kit available right here at

What suspension kit should I use? I want to get a full suspension kit through American Muscle but I'm not sure how low I should go with it. My plan is to add a Cervinis side exhaust kit but I've heard you have to be careful with lowered mustangs if you use that setup. I'm leaning toward one of the Eibach kits. What should I do?


  • get the body kit first.install it on the stock chassis with the tires and rims you are going with then choose which lowering kit will meet your ground clearance needs.

Did you have to add and castor/camber plates with this kit? Hi, I want this kit but don't want to chew through tires any faster then I already do. I didn't see any castor/ camber plates on the Blackout product list. Do I need them? If not I'll be ordering today! Thanks


  • If you don't plan seriously tracking the car then you can just get the adjustable bolts to get your car back into alignment. This is the link for the bolts.

    Much Better than I expected

    First, let me tell you that I researched this decision for @ 1 year. WHY you ask? I began by researching the spring rates of Many different companies including Eibach, Ford Performance, Steeda, Steeda Lite, Maximum Motorsports, HandR etc, etc. What I found was most companies springs are a fixed rate spring that is 20 - 30 stiffer than the stock variable rate spring. Therefore, I decided that these fixed rate springs would be far less forgiving for daily street or highway miles and would be somewhat uncomfortable over potholes or highway expansion joints in my 14 GT Convertible over the stock springs. I read and researched forums where people replaced only the springs and were not happy with the ride quality or the drop. I can say that this is the best of both worlds. The stock shocks were not designed to match up with higher rate springs, and therefore, will not drop the car as much as Eibach states. By replacing both the stock shocks and springs with a system that is engineered specifically for this combination is a no brainier. I used to ride motorcycles and upgraded my shocks on a bike to a Penske shock and spring and the difference was huge. I also researched the Sport-Plus kit and contacted Eibach to find the spring rates on this system. The spring rates were almost identical, but with more of a drop. Replacing stock components with this system firmed up the ride, and removed the floating over road dips. The car lowered the amount that Eibach states, maybe a bit more that they claim which is great. I get a smooth ride but not soft and mushy as the stock ride in a convertible is. Nosedive under braking is almost non-existent. Turns are tighter but not bone jarring hard. If you are considering replacing your springs, please make sure you also replace your shocks with a system that is engineered to match the components. By going with this system, I was assured that it will work as their engineers intend it to. I hope to upload some potot's later this week to show the difference in stock and the new ride height. By the way I'm 57 years old and this is my 3rd mustang. I just wish I would have changed out the springs and shocks on my 2001 Cobra convertible, because I would have kept the car.

    So I'm a High Performance Drivers Education instructor for PCA and other clubs, and have owned GT3, Porsche Turbo, and other high end cars, tracking all of them. When I bought my Mustang, the first thing I thought was "WOW Ford has come a long way" And "Boy we need to lower that suspension." Having played with cars for more than two decades I knew I wanted a matched shock/strut and spring combo, and I've always been a fan of adjustable swaybars, so I went with the Pro PLUS kit for my 2012 GT. The rear system installs in less than 2 hours, start to finish. However, the front suspension will take longer and you will need specialty tools to aid you. I am fortunate that I own a very well equipped shop with TWO lifts, and the front setup still took 3 hours. Be careful installing the swaybar, as clipping it upside down puts it very close to the crank pulley/serpantine belt. Now for the good... This suspension transformed this Mustang. For a live axle car, I'm floored at how it transitions from corner to corner, and how it now puts the power down mid corner! The only DING to the package is this: Eibach went thru great pains to provide really nice hardware throughout the system. They also provide camber bolts for the front suspension so you don't have to worry about an alignment. However, lots of people are ordering the kit and not buying the camber bolts. Eibach should add it as an OPTION or just include the bolts and charge the customer accordingly. Otherwise, this is a GREAT KIT and my first mod after only a month of owning the car. No squeeks, not rattles. And the car is truly transformed!!

    Great Look and Ride

    This handling kit gives your Mustang the ability to actually hit 1G turns on your Track Apps before breaking the rear tires loose. It's very exciting! Now that I have installed this kit the car just "feels" in tune with the road. I also have my steering in "Sport mode". The appearance this kit gives the car is just fantastic. It takes you from, "I have a mustang" to "I have a MUSTANG!". Other pieces I would suggest picking up would be a PanHard Bar. I picked up the BMR. When you lower the car there is a good chance the axle will shift slightly to the driver's side. Install a good PanHard Bar to correct this; it's easy to install while you're doing the back sway bars from the Eibach kit. Also picked up the Eibach camber adjustment bolts. Alignment guy told me those were a ton better then the factory installed ones and thanked me for supplying them when he did the alignment.

    Great System

    The system was all in the box. I just had to install and I was good to go. I didn't need a caster/camber plate but I think I probably should have gotten the GT500 plates just to be safe. I also got a BMR Panhard Rod with it to ensure my rear end wasn't going to be out of alignment. It proved to be extremely necessary. Love the system, very quiet and rides smoothly. I have had eibachs in my Mustangs in the past and I dont think ill use anything else. I do wish they had more detailed instructions with the product but I managed to find some 3rd party instructions online and got it done in a day.

    Great Kit

    I Love this kit. The car handles the way it should and the stance is perfect for me (not too low to be a nuisance because it’s daily driven). The actual drop ended up being a full inch in the front and rear. Eibach advertises 1.5 inch in rear but after 2 weeks, it’s still an inch which is ok with me because we have my son in the back seat most of the time. The ride is not harsh like I thought it would be. It is nice and tight in the turns and stays much flatter than stock. I did need the camber bolts to bring my alignment back into specs, but I ordered them at the same time as the kit so no big deal (was expecting it). I also installed the K&M Adjustable PHB at the same time which allowed me to center up the rearend after all was done. I think I may be saving gas because I don’t have to slowdown in turns like I used to. My only beef was the instructions contained no torque specs. At first I didn’t have the rear sway bar tight enough which caused a knocking sound when I went over bumps. The tech guys at American Muscle worked with me to figure out the source of the problem. After torqueing the sway to 75 ft lbs, that solved the problem.

    Eibach Pro-System plus

    I recommend this product for anybody looking to improve handling and give you car that aggressive look. The job took less than a half day. The shocks and struts were packed nice ready to go and installed nicely. However, Eibach forgot the bushing kit for the swaybars so I had to resuse the original Ford gear and widen them to accomodate the larger sway bars. I called American Muscle Customer Service and they were more than happy to run the missing pieces down. I expect them this week. The ride is tight with no body roll and the alignment turned out to be dead on at the end of the project. The project car was lowered as they stated and has a great stance. That ugly wheel gap is gone and now have a mustang with a 5.0 that can carve some serious corners. Had Eibach shipped the bushings for the sway bar, the project would be done. Not a big deal because putting them on will take less than an hour when they arrive. I recommend this product highly and for the price and free shipping, it's unbeatable.

    The good & the bad:

    The good: This kit completely eliminated body roll and immensely improved the car's handling. The car now takes corners like a champ and feels incredibly firm. The bad: The rear developed a squeak after the installation (just needed lube/adjustments, no biggie) but after looking everything over at the shop, the mechanics told me the left shock is busted and the right one is on its way. This is only after a few months after the install mind you.. If you're planing on doing work to the suspension I would buy the parts separately (and not get eibach shocks) to avoid multiple installation fees.

    How to change your car from a furious slider to a balanced carver.

    In short this kit is amazing. Though I do not recommend the installation to be done at home, it seems simple enough. Be fair warned that you will need camber bolts to correct the alignment once finished, or at least i needed it for my 2013 Mustang. A panhard bar is recommended however I do not have one installed and alignment looks and feels perfect. The ride is of course rougher, but more connected to the road. I live in Norfolk, which can really eat away at your suspension. This kit keeps those wheels planted even going around a corner that has small potholes everywhere. Could not ask for more control. If you do not have recaro seats like me then you will still slide in your seat but your car is going to stay planted without question. No more huge nose dives, and no more front lift when you are gunning it, the kit makes my car feel like a well balanced car finally. Could not ask for more of an outstanding product (besides camber bolts to be included)
