Review & Installation Video

Review & Install Video

Hey guys, Stephanie with here with my review and an install of the Eibach Pro-Street Coil Over Kit available for all '79 to '04 Mustangs except those with IRS of course. In this video we're going to go over a few different topics with this coil over kit but mostly we're going to talk about the performance abilities of this kit and the install. I'm going to cover the install in more detail later. But I'll tell you right now that this install is straightforward but it is a little bit of work, so I'm going to call it a two out of three wrenches on the difficulty meter. The Eibach Pro-Street Coil Overs are going to be for the Mustang owners out there that are looking to get away from the fixed drop of a lowering spring and for someone that's looking for more of a basic coil over kit. There are a couple of options out there when it comes to coil overs and the adjustability that they offer, and this kit offers height adjustability. Even being more of a basic kit, a set of coil overs like this one is going to have a big impact on handling. If we look at coil overs compared to lowering springs, just know that we aren't comparing apples to apples. Typically a lowering spring is going to be best for someone that's looking to simply lower their car and doesn't mind a stiffer ride. The spring rate in the lowering spring is not going to be as aggressive as in a coil over because they're mostly designed to be used with the stock shocks and struts. Coil overs like these, on the other hand, come with shocks and struts that are set to take the abuse of a lowered car, and these are going to be designed to work with the coil over spring rates. If we look right into this kit, right away we're going to be talking about height adjustability which I think is one of the biggest pluses when choosing a coil over setup as opposed to the traditional aftermarket static spring setup. We're going to see that coil overs offer a fully customizable range of height adjustment. This kit offers a drop for the front and rear of the car that'll allow you to lower the car up to two-and-a-half inches. This means that you can set your ride height anywhere in the range of adjustment depending on what you're looking for. This kit gives you height adjustability. The compression and rebound on the shocks and struts are already predetermined for you which is what makes this more of a basic kit. The shocks are monotube shocks and they also come with spherical upper bushing mounts which are going to be more performance based than your factory setup and they're going to function better with the coil overs. This kit is going to include two front strut assemblies, two rear shocks, two rear springs, helper springs and your adjustment tool. Your adjustment tool is going to be your way to adjust your coil over height which you can see your threads right here in the actual strut body. Now, this is better than your other type of coil over where you literally need to turn a spring perch to compress the spring against the top hat in order to change ride height. The problem with this is that it puts preload on the springs and you're already setting yourself up to lose some handling performance. So this is a better design because you're actually expanding or compressing the length of the coil over itself. This isn't going to change the compression of the spring and it's a better way to adjust height. Getting into some more of the specifics about the construction here, other than the fully threaded body you're looking at stainless steel. The springs are linear springs which give you nice handling performance, and the springs are designed for the abuse of the coil over. Of course, these have a factory style bracket which makes these a direct replacement and a direct bolt on. When we start to look at price you're going to notice that this kit is one of the less expensive options when you look at coil overs. It has a price tag that's very close to the $1500 mark. You do have some other options when it comes to coil over kits, and they do offer different things. Just make sure that you guys check them out and get what you're looking for. This is a bolt on kit, guys, and it'll work for both coupe and convertible models. There's no permanent modification necessary but there is a fair amount of work involved with the install, a few hours or so, so I'll call this a two out of three wrenches on our scale when we look at overall difficulty. The work is straightforward and ultimately you're going to need a decent socket set, jack and jack stands or a lift to get the job done. Again, it's nothing too hard but just a little time consuming. You have to break down everything like your calipers and rotors and get your old shock and strut and spring setup out. Then, you've got to get your new setup in. Don't forget you might need a little extra time to get the ride height dialed in to your liking. You may end up having to do a few adjustments to get the car to be where you want it to be, and then you have to make sure it's even on each side. You're going to want to make sure that you're setting it up for whatever you plan on doing for your car and for the performance that you want out of it whether it be a drag strip, a cornering beast or just a low car in general. Keep in mind that after tweaking this much of your car's suspension and ride height you're probably going to need a good alignment to make sure everything's good and in spec. Okay, so overall the Eibach Pro-Street Coil Over Kit is a high-quality kit that's going to offer a lot of room to adjust ride height. Its design means adjustment on the strut tubes themselves which is superior to other methods and offers a wide range of adjustment. As always, don't just take my word for it especially when it comes to something of this nature. I always encourage you to check it out more online for yourself and look at your other options out there. I'm Stephanie, and for all things Mustang, keep it right here at

Lowering Springs no longer required? Will I no longer need stock springs or lowering springs on my mustang if these are installed? As I understand it, these would move the spring out to the shocks and struts. Am I correct? Help would sure be appreciated. Thank you!

  • You're correct Sir, The Eibach Pro-Street Coil Over Kit completely replaces all factory designed shocks, struts, and typical rear independent coil springs setup.

Why change to a coil over system? Are there any benefits to coil over kits opposed to getting new shocks, struts, and springs?


Helpful (3)
  • Not exactly from the should I buy this or that stand point but in the long run, yes. The real question is this adjustable enough for you? If ride height is all you are looking for then consider the weight savings in the form of smaller springs and being able to get tubular a-arms. Also everything in this kit is matched to work together, None of that "Will these spring work with these shocks?" type stuff. Also consider the fact these are adjustable for ride height. If you decide your car is sitting too low or too high put it on the jack stand and take the wheels off and make an adjustment. Something you can't do with springs. I like mine alot on my 04 and the ride was smoother compared to my previous lowering spring type setup I had before.

clearance issues? Just wondering with this kit is there gonna be clearance issues with the tires? I plan on running stock rim's and tires for now (88gt) but someday i plan on going with some after market rim's.


Helpful (3)
  • Normal off set of factory rims allows for the most clearance. However factory wheel set-up will limit the benefits of coil over kits severely. To get the most out of coil over kits would require specialized A-arms, rear control arms, and high performance wheels. Basically complete suspension overhaul should be the end result goal with race entry level coil over kits.

Would i need to buy the irs for the coilovers or can I install without them?


Helpful (0)
  • Hello, This system fits all models EXCEPT irs fitted mustangs. So no you would not need irs in order to install these coil overs


I want to know all additional components are necessary for a complete install. For example camber plates, new ball joints, any connectors needed, new stabilization shocks for the rear (i.e. To keep wheels on the ground with acceleration) etc. I have over 100,000 miles on it now so it probably should be upgraded. Thank you.

    Excellent quality product!!

    I haven't installed my Eibach coilover kit yet because my car is in storage now. But I can say that the quality of the parts is really good and carefully wrapped. The transaction and shipping with/from American Muscle were easy and fast. I recommend them for all your Mustang needs. The only "bad" thing I found was that the Eibach caster/camber kit is not sold on the American Muscle Web site, I have to buy it elsewhere since I am not sure if the other brand's kits work with those coil overs.

    Eibach pro street s

    Kit was fairly easy to install however they leave out one major detail. Eibach has recently changed the front strut overall length requiring you to have buy adapter perch feet that are about 70 bucks for the front. If you have spherical bearing camber plates, the only way to allow the threaded portion of the strut to protrude through the plate is by allowing the vehicles full body weight to compress the strut on the ground. It took a while to figure this out by calling maximum motorsports and eibach directly multiple times. The eibach tech on the phone and in emails said that they are going to implement a TSB into thier instructions for the pro kit s and perch feet adapters for spherical camber plates. Although once I had the suspension dialed in at my local alignment shop, the car drives like a dream. I highly recommend doing this mod because my acceleration and body roll have improved drastically from lack of body flex, NOTE: changed both RLCA'S and RUCA'S at time of install. Just frustrating that the instructions or lack thereof made this take way longer than it should of. The part number for the perch feet adapters is eibach p/n 5.1018k.

    Improved Composure and Confidence

    My initial impressions are very good for this product. Although I have not had the car aligned yet, I did take it for about a 10-mile shakedown to make sure everything was working properly. What I found was that the suspension had much improved composure, ride quality was about the same - if not a bit softer than stock - and overall confidence in what the car was doing increased a lot. The shock control was lightyears ahead of the stock KYBs - but mine had over 100,000 miles on them so it wasn't a fair comparison in some ways. I was particularly impressed by the lack of lateral movement in the rear axle with the new setup. Most everything fit together as advertised. The only exception was some hardware washers that I purchased at the suggestion of LMR's video instructions. It will help you get more threads through the shock tower if you use their trick. I used a combination of Eibach's instruction manual and LMR's video ( I would HIGHLY recommend doing this install with a buddy. I was fortunate enough to have my dad help me. There are parts of the job, especially the rear end, that you basically need two people because you need one person to operate the jack while someone else moves things (like the shocks) into place. Overall this kit just plain rocks. The ride height adjustability is awesome, the new-found control is awesome, and the ability to adjust your stance at any time is great. To adjust the ride height, you simply use the the Eibach tool to twist the collars up or down depending on whether you want it higher or lower. Wonderful product! Very grateful to Eibach for making this.

The product fit well and the performance & ride quality were great. Ride height adjustment was simple & the car looks great. I would reccomend this product to anyone interested in getting Coil-Overs & wanting to lower their car for great looks & performance.

    Confidence Inspiring Handling for your Mustang!

    This is what you need if your trying to get your Mustang planted, want a coilover kit, and you are on a budget for it. The springs and struts are matched perfectly to each other. The rear install can be done in an hour tops but the front is a little more complicated and requires some expertise or prior knowledge on this type of install. It took me a good 8 hours on this install however because Eibachs instructions are garbage and don't contribute any tips to get the job done. They lowered my car in the front as far as I would ever plan on going (about 1 inch gap left between tire and fender) but I didn't quite get the low I wanted out of the most likely due to it being similar setup to lowering springs. On that note you can do this install easily without spring compressors and a spanner wrench. The helper springs provide this little luxury without complicating the installation. You would however need a spanner wrench if you were looking for the ride height to be more tuned towards a drag setup I believe but I have made adjustments with the provided tools with the tires off. The kit will need to be paired with a sway bar kit to keep the car more level but overall I am very happy with this buy. On a final note that doesn't have anything to do with the product is shipping. It took 2 weeks to get here because they are made to order and shipped directly from Eibach. So if you are thinking about it I don't think you have any regrets buying this one!

    Excellent Product Very Easy to Install

    I love these coil overs for the mustang, They were easy to install but with problem i encountered, I didn't have the tools to complete the job. Other then the pictures being very hard to decipher the directions were very straight forward. I had to spend around 500 dollars to throw everything together by a professional installation at a local ordinary repair shop due to my valiant attempt with horrible tools went unsuccessful. The drop on my mustang is about 1.5 inches in the front and its a thread higher in the back to give it a much more aggressive look with out losing stability in the rear. These deliver a very smooth ride with that race car stiff feeling around the bends that we all crave, I highly recommend this if you are skilled and have the tools to complete the job, I do recommend this product to those who are not a skilled mechanic or technician to bring it to a local repair or speed shop.

    A little dissapointed

    I'm not sure what's going on but I've had these coils since November last year, and the ride quality isn't all that great. My ride is rough but not in a good way, I expected it 2 feel firm and sporty but it doesn't. I also still experience body roll and over steer....mind you I have coils sway bars camber plates bump steer kit and upper / lower control arms in the rear. I was sure to expect a sporty ride but I don't have it, I'm confused. Also the front coils make a creaking noise ever time I go over slight bumps or enter my drive way.

    Superior Quality

    These coilovers have a great range of height adjustment. They are very easy to adjust with the tools that were provided. I am amazed at how well my 01 GT hugs the road around corners. I don't feel like the lowest height setting is "stupid low" because it's my daily driver and I get around just fine and smoothly. The suspension is a bit stiffer than stock, but I personally love it. These coilovers will definitely change the look of your Mustang at any height setting, as it's a major improvement over the ridiculous stock height.

    I was riding on stock struts for about 150000 miles and needed and upgrade. The handling improvement is night and day. Feels like a completely different car. I love the fact that I can change the ride height depending on what kind of driving I'm doing. Installation was not that bad. I recommend the bump steer kit and ball joints.
