    Review & Install Video

    The Eibach Sportline lowering springs are going to be a good option for the owners out there who are looking for a progressive-rate spring that'll give an aggressive drop and aggressive handling. The spring is perfect for those owners out there that are willing to sacrifice some of the nicer amenities of a soft ride quality in order to gain one of the biggest drops from a lowering spring. These springs will lower the car 1.7 inches in the front and 1.5 in the rear. As far as the install goes, you're looking at a two out of three wrenches on the difficulty meter and you can plan on spending a half a day to get the install done. The Sportline springs are a very popular aftermarket spring. Not just for these cars, but across multiple generations, because of the amount of drop that they offer. Right now, this kit is going to be your go-to choice if you're looking to drop the car as low as possible on a lowering spring. Even though these offer a lot of drop, the Sportlines feature a progressive or dual-rate spring, which is always a great choice for a streetcar. Because it'll be relatively comfortable in cruising, but progressively get firmer when you start pushing the car and that's reflected in the spring rates. Some of the benefits of using a progressive-rate spring like this include improved roll control over a traditional linear spring, especially when paired with a set of matched sway bars, like the Eibach sway bars. Ride quality is something that's going to be subjective. But I can at least give you an idea of what to expect here. Taking into consideration the fact that these offer a good amount of drop and that they are progressive, you can definitely expect a firmer ride quality. You are going to notice more bumps in the road and have more of what I call a "sporty" ride quality. But it isn't a bad ride quality at all. Another thing that I wanted to bring up here is caster camber plates. Caster camber plates are always going to be a good idea when you lower your car. But they don't really become necessary until you hit one and a half inches or lower. In this case, I'd say that a set of CC plates are needed if you don't already have a set, since these offer a big drop. That way, you know that you'll be able to get your car limit back in spec after the install. Speaking of extra things here, it's also always a good idea to pick up some new spring isolators, especially if they have a lot of miles on them. These springs are still going to allow the car to clear the stock wheels and tires. But they'll also clear the preconfigured wheel and tire combo kits that we offer here on the site for the specific generations, so you won't have to worry about rubbing. I do want to specify that these will fit the '79 to '04 V8 coupes and the '99 to '04 V6 convertible Mustangs. They will not fit the '99 to '04 Cobras due to the IRS. When it comes to price, you can expect to pay just north of the $250 mark for these springs. If this price sounds a bit high for you, you can always shop around for another brand and save a little bit of money. SR Performance is very budget-friendly, and Vogtland, ST Suspension, and Ford Performance all have similar offerings for a touch less than these springs. As far as the install goes, this isn't a difficult install, but it does involve a lot of work. I'm going to call this one a two out of three wrenches on the difficulty meter. You're looking at spending a half a day in the garage, and you'll need an assortment of wrenches and sockets, and of course a spring compressor, and a jack and jack stands if you don't have access to a lift. This is all straightforward and it's something that most people can handle themselves. You're going to have to break down everything like your calipers and rotors, and get your old shock and strut, and spring setup out. Luckily, since this kit is a direct replacement, it makes the install easier. Your springs and struts install separately. So you're looking at needing to slide the front struts into place and getting the top nuts back on, as well as getting the spring seated and in place. The rear is a little bit different, but you're still looking at needing to remove your factory component. After the springs are installed, the shocks can be installed and those go in the same way the factory ones came out, and that's pretty much it. Keep in mind that after tweaking this much of your car's suspension, you're going to need an alignment to make sure everything still looks good and is in spec. That's going to do it for my review of the Eibach Sportline spring kit for the '79 to '04 V8 coupe and the '99 to '04 V6 convertible. But you can check these out more online right here, at americanmuscle.com.

    Better Handling. Give your Mustang the sportscar type handling it deserves with an Eibach Sportline Spring Kit. This lowering spring kit lowers your Mustang's ride and center of gravity even more than the legendary Eibach Pro-Kit, for maximum improvement in acceleration, cornering, and braking performance. A set of Eibach Sportline springs are the no-comprimise choice for the enthuisast that still needs a streetable car.

    Maximum Lowering. Eibach's Sportline Spring Kits are designed to deliver the lowest possible drop for a racecar like look and handling while still maintaining exceptional ride quality.

    Progressive Design. Eibach uses their proprietary progressive spring design to create the Sportline springs. The result is a spring that delivers the maximum lowering and aggressive stance a true enthusiast demands, without compromising safety or ride quality.

    Recommended Upgrade. When installing new springs you should also replace your old worn out rubber Spring Isolators with a new set of Polyurethane Spring Isolators, see drop down option above.

    Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your factory 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 Eibach Sportline springs is designed for 1979 to 2004 V8 Mustang Coupes and the 1999 to 2004 V6 Convertible Mustangs. Will not fit 1999 to 2004 SVT Cobra's with Independent Rear Suspension (IRS). Sold as a set of 4.

    Will these fit the 99 v6 coupe? If so will it actually lower it? Thanks AM

    • Although advertised and designed for the 99 V6 convertible, it will certainly fit the coup as well. The convertibles are heavier than the coups, so the springs will be more stiff than intended, and the Mustang won't drop as much as advertised, due to its lighter weight in comparison.

    I have a 1996 convertible GT and was wondering if these would fit.

    • The Eibach Sportline Spring Kit would work with the convertible models, however, is not set up for the weight difference from the convertible to the coupe models and will react differently.

    I have a 2000 gt 275 in front 315 in rear will these work thank u

    • The Eibach Sportline Spring Kit will work with those tire sizes as long as the wheel offset is correct. All of our Mustang wheels will allow this to work, as well as any aftermarket wheels sharing the same offset for that given size.

    I am planning on putting 20" Rovos on my 2002 GT. Will these springs be too low?

    • The Eibach Sportline Spring Kit will fit 20 inch wheels. However fitment will depend on the tire size you add as well.

      Eibach Sportline Lowering Springs.

      Installed these on my 2001 GT combined with new damping adjustable shocks and struts (KYB AGX) Steeda bumpsteer kit and the ride quality and looks are great ! Compared to stock , the car corners way better and goes over bumps much smoother. Used the SR Performance Polyurethane Spring Isolators kit for the rear (top and bottom) , and only used the top isolators in the front (didn't use the bottom ones). Got about a 2" drop all around. Took about 4-5 hours to install (front and rear springs bumpsteer kit).

      Awesome quality !

      Eibach is quality springs the best alternative to coil overs cause lowering springs are the cheap option but if you don't got $2000 to blow I highly highly suggest these springs. Quick note if you have an x pipe be careful your clamps will scrap going into certain driveways if they're steep

      As expected from Eibach

      Previous owner cut springs leading to a bunch of issues.If you’re going to put money into your car do it right the first time. Nice drop unfortunately the car has 20s still no rubbing or clearance issues. All my mustangs have some type of Eibach kit on them worth it every time

      Lowering springs?

      I saw the American Muscle video on this product and they said that it will lower the front 1 7 inches and the back at just little over an inch. I installed this springs a little over a week now and I cant tell much difference in height. Yes, it is a little lower but not what was advertised and not what I was expecting for the money. I probably would not do it again, because its does lower the car enough for the money. I installed them on my 2003 Mach 1. I hope this review helps you all in deciding how to make your purchase.

      Solid springs

      Lowered the car and the looks are a thousand times better. Bigger drop than expected. Ride quality is definitely affected but its not an unbearable ride , bumpy roads are bumpy but its something to be expected with lowering your car. I do scrape here and there on speed bumps and big dips something im still adjusting too. Im on stock 17s. From what I read on here I needed caster camber plates to realign the car after lowering but when I went to get my alignment I was told they were not necessary so I returned them. (Hoping what they told me is true and don't have issues down the line) overall great product and very happy with the looks.

      Eibach sportline springs Amazing look.

      The drop on the eibach sportline lowering springs was exactly what I was looking for. Expensive compared to others but had the drop I wanted on my 1996 GT convertible. I scrapes here and there but to me worth the looks. Handles amazing compared to the stock springs, ride a little bouncy but what do you expect from stock struts and shocks. That will be next on my list, thanks AM!

      Lowering springs

      Very easy to install, the whole job took about 4 1/2 hours and that was shocks, springs and caster/camber plates. Of coarse it helps when your car is rust free. The springs set the car just where I wanted it, the ride is a little more harsh but that is to be expected, highly recommend these springs.

      I was excited in getting the springs. When i installed them i was happy that i was getting rid of the big gaps in the wheel well. The back was perfect. But i was disappointed in the front. Even though it drop 1.7 inch i still have a 2 1/2. Gap. Iwant to go lower but dont know what to do since i just spent money on these. But besides that the springs work great and the rear looks awsome.
