Review & Install Video

Hey, Justin here with, and I’m going to be talking a little more about the Eibach Pro kit springs, fitting your 2011 and newer Mustang. If you’ve been modding cars for any duration of time, then chances are you’re very familiar with the name Eibach, that’s because they are without a doubt one of the biggest and most trusted names in aftermarket suspension, and have been for quite some time. So what can you expect from Eibach’s pro kit springs? Well, drop wise the pro kit is pretty conservative compared to other springs, take Eibachs sport line for instance, the drop is roughly a half inch to an inch in front, and about an inch to an inch and a half in the rear depending on your ride. We do list the model specific drops under the description tab on this product page. So basically, if you don’t want your ride to be slammed, the pro kit is a great choice, having said that the drop is enough to get rid of some of that unsightly wheel gap, ultimately giving your ride a more aggressive stance. So you know what to expect from the Pro kit appearance wise, but what about your handling performance? Well, a good set of progressive rate springs like these Eibachs are going to do more than you think. They’re going to help eliminate squat on hard launches, nose dive during braking, and body roll on the corners. Basically the car is going to feel more capable and more responsive all around, ultimately making for a better driving experience. So, does installing these new springs mean you have to change out your shocks and struts? Well, that’s up to you, ultimately you can’t go wrong by pairing these new springs up with some performance shocks and struts, that are better designed to work with that lower ride height, and higher spring rate, however since the pro kit does offer a pretty mild drop, your factory stuff should work fine as long as everything’s in good shape, however if it’s not then you might want to consider upgrading or even checking out Eibach’s pro system plus, which does come with everything you need to completely revamp your suspension. Installing a new set of springs isn’t exactly something I’d recommend for the first time wrencher out there, this is because you need to use some specialized tools like a spring compressor, to remove the factory springs and install the new Eibachs. Because of this we highly recommend leaving this one in the hands of the professionals, on the other hand, if you know your way around the garage, and you have access to all the tools needed, just leave yourself about 4 hours to get the job done. Whenever you alter the ride height of your vehicle, you should ideally take it to an alignment shop just to get everything checked out, especially your camber. If you do need some additional adjustment, Eibach offers a very affordable solution in the form of their Camber adjustment bolts, just be sure to let the springs settle about a week or so before you take the car in. So if you’re looking for a relatively mild drop that will have a big impact on your car’s handling performance, then be sure to check out Eibach’s pro kit springs available right here at

Performance Handling. These Eibach Pro-Kit Progressive Rate Springs will lower your Mustang's center of gravity, reducing squat during acceleration, body roll in the corners and excessive nose-dive under hard braking. A set of Eibach Springs are great for daily driving, street, and even track use.

Aggressive Appearance. Not only does the Eibach Pro Kit Spring Set improve the handling of your Mustang, but it also improves it's appearance by lowering the ride height to get rid of that ugly 4x4 look that they roll out of the factory with for a more aggressive stance.
  • Lowers 2011-2014 GT Coupe: Front - 1.0", Rear - 1.5"
  • Lowers 2011-2014 GT Convertible: Front - 1.0", Rear - 1.5"
  • Lowers 2012-2014 BOSS Coupe: Front - 0.6", Rear - 1.0"
  • Lowers 2011-2014 V6 Coupe: Front - 0.8", Rear - 1.2"
  • Lowers 2011-2014 V6 Convertible: Front - 0.8", Rear - 1.2"

Progressive Design. Eibach's proprietary progressive spring design provides the ultimate balance to deliver aggressive good looks and high performance handling, without ever compromising safety or ride quality.

Better MPG. Independent testing has shown that lowering a car's ride height improves aerodynamic efficiency by forcing more air over the car and less underneath reducing drag, resulting in higher top speeds at the track and better fuel economy on the highways.

Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your stock size wheels and tires, as well as AmericanMuscle's pre-configured wheel and tire combo kits (specific to your generation), to assure proper clearance with no rubbing issues.

Application. This set of four Eibach Pro Springs are designed for use on the 2011-2014 GT, V6 and BOSS Mustangs.

Ask a Question

Is an adjustable panhard bar really needed with this set? And how are the speed bumps?


  • Yes and No, it really depends on what you’re looking for. If lower your Mustang is the only goal in mind cheaply as possible, then No. If getting the most out of handling ability as well, then Yes. When you drop the rear 1.5” the axle will lean 3/8” off center to the driver’s side. Not really noticeable by sight, but when you take a left hand curve your Mustang will generate more body roll to the right in comparison. Also the panhard is perfectly in line with the axle limiting right to left handling differences felt at factory level so for me it was important to have all four wheel in perfect alignment to maintain even handling characteristics, which can only be achieved with the adjustable panhard bar. I haven’t had any issues with speed bumps, but I’m also watchful for them as well. One time I thought I might have bit off more than I can chew and I drove slowly so not to bounce downward on the backside of a rather large speed bump and I was successful without bottoming out. If you go slow enough you will not get hung up and should have an opportunity to back off if you were to hear the slightest scrape.

Does you recommend camber bolts for this product? I have 2012 GT with the Brembo kit


  • Yes, as long as it is not a track car. On the street you are fine using Camber Bolts as the Eibach Pro Kit only lowers the car about an inch in the front and 1.5" in the rear. Although this doesn't seem like much - (its not) BUT- it gets rid of the factory wheel well gaps that are so ugly. The factory suspension will only allow so much camber adjustment, so with these bolts you can fix that small amount of negative camber that will happen. Plus the camber bolts are very cheap - vs. wearing out your tires at an accelerated rate with the negative camber. How can you lose?

I'm looking to purchase either these springs or the entire kit. I just need to verify that my Nitto NT555 G2 255/40R19 front and 295/35R20 rear tires will clear with the estimated drop of 1" front and 1.5" rear on my 2014 Mustang GT convertible.


  • These springs will fit with your NITTO NT555 G2 255/40R19's & 295/35R20's as we are able to confirm fitment of those tires with upwards of a 2" drop.

Hello! I have a 2010 Ford Mustang, does this fit to this model?

I just install these springs on my 2014 GT Track pack. I think my rear wheels dont drop the 1.5" . Stil look with a big gap. Will the spring sit whith the time or no? Is the rear shock of the track pack are different? Thanks.


  • Track Pack equipped Mustangs use different springs than standard Mustangs, and will sit slightly lower than their non track pack equivalents, so the full 1.5" of drop would not be seen on a Track Pack car with the Eibach Pro-Kit Springs. The rear springs will take time to settle, since less weight is on them. once they have settled by going through their paces with driving, you should begin to see your final ride height.

I just need to verify that my Mickey Thompson street comp 255/35r20 front and 305/35r20 will fit on 2014 mustang v6?


  • With these or any lowering spring, the largest we can guarantee fitment for up to 2 inches would be a 255 up front and a 275 in the rear. So it will be very possible that your 305 will rub.

    Almost perfect, should be OEM spring.

    I didn't want a super aggressive drop on my Mustang, I just wanted to firm up some of the floatiness of the suspension. I debated adding stiffer shocks, camber bolts, adjustable panhard bars, and stronger shock mounts, and eventually just put the springs on by themselves. It worked out fine that way. I installed the Eibach Pro kit on a 2012 V6 Mustang coupe base model. Install wasn't too tough. The springs can all be changed without a spring compressor. Put stands under the engine cradle, and put a jack under the conrol arm and slowly lower it to take the tension off the spring. It's easier and safe if you go slowly. It took me about 3 hours to change out all the springs. The back was maybe 45 minutes, front 2 hours overall. Handling is firmed up by about a third, but the ride is still a little softer than I would've liked. I didn't want a race car ride at all, but I was expecting a little firmer handling than I got. It's overall a VERY easy daily driver, absolutely this is the spring Ford should have as stock. My only complaint is that this didn't lower the rear as much as it says it will. I took meticulous measurements and found only a 7/8" drop front and rear. It says in the description to expect a 1.2" drop on the rear of the V6. Nope, the rear still rides with a little too much gap. As for the axle, it shifted about 1/8" to the driver side. No biggie. Overall well worth it, but if I had to do it again I would have liked another 15% more spring rate and a little less fender gap. Its still an easy daily commuter car that could use a bit more control in aggressive cornering. I will post pics, its a Grabber blue V6.

    • Response from AmericanMuscle

      It's possible if you just installed the springs, that they still need time to settle to the estimated drop. Springs don't show the exact full drop immediately after installation. Hope this helps!

    Great improvement

    Just purchased these springs and installed them. It took about 2 hours to complete both ends. I did not want a significant drop so I went with the Pro Kit. These take away that 4x4 look of stock and give you a perfect height. I was on the wall on choosing Pro Kit/Sportline, but I think I made the right choice. Awesome spring for the money and the ease of install was good.

    Great mod

    I bought these to make my '12 GT look more like a sports car and less like a 4x4. For those who are wondering, these springs work with the factory hardware. YOU DON'T NEED to buy anything else. A little stiffer ride, but much better cornering and handling. I picked up 1 or 2 mpg's as well. Great product.

    Dude.... ya!!!

    My 2014 Ford Mustang does not look like a Ford Raptor anymore... yippppy!!!!! I just got the springs installed with a WhiteLine panhard bar. I did not get an alignment done because I want the springs to set or whatever they say. But after the springs and bar were installed, I took it for a drive and it was very nice. I am also happy with the way it sits. As of right now, the front is .5 inches lower and the rear is almost 1 inch lower. The ride is a little stiffer and I like it. I haven't really taken it on the back roads but from a few fast turns, it sure is more stable. Less nose dive, less squat, better and more stable turns.... basically everything everyone is saying. My local shop charged me $280 and it took them about 3 hours. Over all, I am very happy so far and I can't wait for the springs to settle so I can look even lower. So as I stated earlier, I didn't get an alignment done and the car drives very good. I can't tell if it's off or not but I will get an alignment done soon.... I also bought the camber bolts just in case I need them during alignment. Shipping took about ten days but that's not a big deal and it was a pleasure dealing with American Muscle as usual.

    Eibach Springs

    I looked at several brands of springs before I settled on the Eibachs and I think I made the right decision. I wanted to get rid of the factory height but I didn't want to slam the car. If you want a really low car these are not what you want, but if you want a good ride with a lower spring this is the ones. I did use an adjustable panhard bar and had to go about 1/4 inch shorter than stock.

    Great Upgrade!!!

    I had a professional shop install these springs for me which took a whole afternoon. I immediately noticed the 4x4 look was gone and my car sat level and in an aggressive manner. The handling capability wasn't very good compared to the way the stang drives now. It feels much better all around and handling has improved greatly. I definitely recommend these for every stang out there... it really is a night and day difference.

    Nice drop, better handling, stiffer ride.

    Provides the perfect stance-received a lot of compliments on the improved look. Not a slammed look but takes away the tire gap. Handling definitely better, much less nose dive on braking and less squatting on acceleration. Ride is a little stiffer. Definitely must buy a pan hard bar but nothing else is immediately needed. Shocks/struts eventually and maybe that'll help with the stiffer ride. This was my second mod and would recommend to anyone

    Worth the time and expense.

    Easy to install except for one part which took a long time to figure out. Without an impact wrench it is hard to take the top nut off of the stack tower. The nut on the 2011 is in a recess. I eventually had to grind down a 22 mm open end wrench so that I could hold the nut and turn the top nut with a socket wrench. The front springs took around three hours to install (I am a neophyte and not a pro). The back springs took 30 minutes. Great ride and it looks really good. Worth the effort. The best tutorial is the pictures included with the American Muscle Ford K springs.

    Perfect for Daily Driver.

    I started out with a track pack mustang, so my springs were already stiffer than the regular GT. I was surprised by the ride I get out of the new Eibachs, actually softened the ride over the smaller road imperfections which are abundant where I live because of lack of street maintenance here. I like the look of the lowered car very much, it's really the reason I bought these springs in the first place, the smoother ride is just a bonus. Even though the ride is better the nose does not dip any more than it did before under braking, or rise any more than before on brisk acceleration, pretty much the latter is a daily occurrence. I don't know if you would want to race with duel rate springs like these, but they work great on my daily driver. What a great product, I highly recommend.

    Less is more... The perfect stance

    Perfect drop without looking overly exaggerated, and definitely gets rid of that nose dive during heavy braking and rear end dive during heavy acceleration. You don't have to worry about scrapping in steep driveways, because mine is pretty steep and didn't scrape while backing out and turning sideways. I paired these with the Koni yellows and Steeda panhard bar to center the rear end all at once, and the car has way more stability and control in the turns from the stock track pack suspension. Definitely more fun to drive during spirited driving. Feels smooth and almost stock while driving you just feel bumps in the road a little more but nothing to significant, but definitely a minor trade off to have a suspension that's ready to carve corners. If you're doing it yourself and its your first time like me, make sure to be careful when doing the front springs because the strut mounts can come apart when removing them from the front springs and cause the ball bearings inside to come out everywear which will cause you to have to reassemble the strut mounts which was very tricky (something that is not mentioned in the diy videos). The fronts took a while but the rear springs where a piece of cake.
