Description
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.

Hey, Justin here with AmericanMuscle.com, 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 AmericanMuscle.com

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

CoreyM

  • 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?

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

Chris3103

  • 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.

Paired with FRPP shock/struts? Is there any reason that these springs can't be paired with FRPP shocks/struts on a 2011 V6? I was looking at the FRPP lowering springs but like the idea of the lesser drop with these springs.

LandToSea

  • Pro-Kit springs work well with FRPP shocks/struts compared to other spring sets with more lowering so you don’t over stress FRPP set-up. If you go pass 1.0” I would recommend changing out FRPP to customized Eibach shocks/struts designed to handle lowering stress loads compression without risking shocks/struts blowouts resulting from excessive wear. Also V6 lighter frontend weight distribution is less likely to over compress FRPP struts compared to heaver V8, which will allow normal strut life. Eibach camber bolts may be necessary for realignment.

    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.

    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.

    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.

    Springs give the car a perfect stance

    The springs provide the perfect drop. Installation was relatively easy, however pay close attention to the strut mounts. I installed these with a friend in about 2.5hrs.

    Not Bad

    Just got these installed couple of days ago and they're not bad at all. The ride quality feels stock if not smoother w/ less body roll. Did not need camber bolts for alignment, it was quick an easy

    Nice Drop

    As advertised. Nice all around drop but gap is still there especially in the back. Ride quality is actually less bouncy from stock track pack suspension but is a bit more harsh. Corners much better and reduced wheel spin on take off. I can actually use 1st and 2nd gear! Would definitely recommend and installed in about 6 hours.

    2014 Mustang gt Vert

    Installed these on my 2014 gt vert, all i can say is wow...it's a different car 100%...corners flat...no longer feels like a boat...minimal brake dive...ride maybe 10% rougher..but thats perfect...took me a bit longer to install as the spring compressors i had were junk...other than that the fronts went on easy...rears, i didnt remove the sub frame vert braces...just lowered the axle as far down to rest on the braces...then jacked up the opposite side until the car almost came off the jack stand, then wiggled out the opposite spring. ...super easy! you will need the adj panhard bar as mine was 3/4 inch to the drivers side. not sure on alinement yet...i want to let it settle abit before i do that. overall...best 250 spent...i just got the Koni Str.ts...will report on those once installed...

    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

    Pretty much as advertised

    I'm pleased with this install. It dropped my car 1" in front and 1-3/8" in back. Ride is firmer. I plan on upgrading to adjustable shocks and struts in the future. No bump steer, but the car does want to track uneven surfaces slightly more, especially under braking.
