Review & Installation Video

Review & Install Video

Hey, guys, Stephanie with americanmuscle.com, here with the Eibach Sportline lowering springs for the 2005 to 2010 GT Mustangs. We're gonna be talking about a few different things with these springs, but mostly we'll talk about what you can expect from these springs in both the performance and looks categories, and we're also gonna talk about the install as well. I'll talk more about the install later, but you're looking at a two out of three wrenches in the difficulty meter. The Eibach Sportline lowering springs are gonna be a good option for the GT owners out there who are looking for a spring that'll give an aggressive drop and more aggressive handling. This 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. Lowering springs have a big impact on these cars. They can completely change the looks of the car without having to change a lot, and the Sportlines offer one of the largest drops for these cars. The Sportlines are gonna drop the GT about 1.6 inches in the front and 2 inches in the rear. Like I said, it doesn't get much lower than this for the S197 from a spring, and this is an aggressive drop. The drop will change slightly depending on if your car is a coupe or a convertible, due to the weight differences between the models. Depending on your wheel and tire setup, this drop is going to eliminate nearly all of the wheel gap that the GT has from the factory and it's gonna leave the car sitting just above the wheels and tires. Now, a one-inch drop is pretty standard across the board for the S197, and I'd say that one inch lower is pretty significant for these cars. I mean significant in both looks and performance changes. So that means that the over one-and-a-half inch to two-inch drop that the Sportlines offer is one of the greater drops that you're gonna be able to find. This drop will lower the car's center of gravity enough to create more track-like handling capabilities. These springs are really gonna reduce squat during acceleration and reduce wheel hop as well. You're also looking at much less body roll during cornering and less nosedive during braking. Lowering the center of gravity this much means that these springs are really gonna change and tighten up the handling of these cars. Now, if you think that this is too much drop or if you really want to hang on to some of those softer ride quality characteristics, Eibach also makes a Pro-Kit lowering spring. Those springs drop the car a touch over one inch all the way around and they will ride differently than the Sportline kit, a little bit more comfortably. To really lay this out, I would say that the Sportline springs are more aggressive and better suited for some track use or those that are really looking for high performance and forceful looks. They're an all the way around more aggressive spring. The Pro-Kit springs, on the other hand, are a great option for those that would like to lower the car and reduce wheel gap but that want to keep the ride quality and streetability in the forefront of their mind as well. This doesn't mean that the Sportline kit won't work on a daily driven car. It'll work just fine. It really all comes down to your personal preference and what you want out of the springs. The Sportline springs, like the Pro-Kit springs, are still a progressive spring. Progressive springs concentrate on providing balance at all times in order to improve handling. Like I said earlier, these springs do provide an aggressive drop but they are still gonna work with both the factory wheels and the preconfigured wheel and tire kits that are on the site. These springs aren't gonna make the car difficult to drive places but you will need to be a little bit more careful. They are gonna be stiffer than the factory springs as well, so you will notice some more road noise. But, I wouldn't say that these give a bad ride quality at all, it's just not as soft as factory. I do want to say that a lot of times when you're shopping for lowering springs, you're also shopping for things like adjustable caster camber plates and a new set of both shocks and struts. In this case, I wouldn't say that caster camber plates are necessarily required, but I will say that a one-and-a-half inch drop is about the limit of where you would need a set of adjustable CC plates in order to get the alignment within spec. It is going to be close, so a set wouldn't be a bad idea at all. At the end of the day it never hurts to have caster camber plates, so if you've got the extra cash, I'd say go ahead. As far as shocks and struts, this goes back to the drop too. I'd say that you can get away with the factory shocks and struts in this case, for at least a little while anyway, but it is gonna come back to how many miles that you have on these components. If your shocks and struts have a ton of miles on them, I would replace them, but if they don't, you can always consider picking up a new set anyways. When it comes to price, these springs are gonna be one of the middle of the road options. They're not the most expensive but they aren't the least expensive either. They cost just under $200, which is slightly less expensive than the Pro-Kit springs. If you're just looking to get your car lower and you aren't concerned with ride quality, there are some other options on the site that cost a little less and will get you where you need to be. On the other hand, if you are concerned with keeping a nicer ride quality and getting as low as possible, then you're shopping in the right place. So the install here is going to take about four hours. I'm gonna call it a two out of three wrenches on the scale. You will need some knowledge to complete this install, so I'd recommend having a knowledgeable helping hand or taking this to a shop for the install, especially since it's always a good idea to get an alignment after the install anyways. This install can be done on jack stands if you don't have access to a lift, but as usual, a lift would be your best bet here. You're gonna need a few tools, including a spring compressor, so make sure you have that before you start the install. You're gonna need to get down to the spring and strut assembly, so everything like the wheels, brakes, and ABS lines will need to be moved out of the way so you can pull the assemblies out of the car. The spring compressor will help you remove the spring from the strut and install the new front springs, which are compressed and installed the same way. The strut assemblies go back in the same way they came out, and the install is the same for both sides. The rear is nearly the same. You will need to disassemble some items to get to the springs, but ultimately you'll be able to lower the rear axle enough to the point where the springs will be free. Just like the front, the rear springs install the same way that they were uninstalled. You install your rubber insulators and your new bump stops are installed, and after the new springs are in, you can begin reinstalling the shocks and everything else that you uninstalled. That's about all it's gonna take. Like I mentioned earlier, a fresh alignment after the install isn't a bad idea. Wrapping things up here, the Eibach Sportline lowering springs offer a spring with an aggressive drop and improvements in handling to make for a car that feels track ready. They drop the car about 1.6 inches in the front and 2 inches in the rear and will leave the car sitting just above the wheels and tires. The springs are not difficult to install, they're in the middle of the pack as far as pricing goes, and you can check them out more online right here at americanmuscle.com.

Better Handling. Give your 2005-2010 GT the sportscar type handling it deserves with an Eibach Sportline Spring Kit.

A set of Eibach Sportline springs are the no-comprimise choice for the enthusiast 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.

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 Eibach Sportline springs is designed for 2005-2010 Mustang GT coupes and convertibles. Sold as a set of four.

Ask a Question

What shocks and struts will work best with this kit? Is the Ford Performance Dynamic Shock Strut Kit a could match?

Scottyboy

Has anyone who installed these springs run into any driveline vibration issues? Should I plan to purchase an adjustable upper control arm when I have these springs installed on my 2008 GT? How important is it to get the proper pinion angle??

Tim

I have a 2008 GT with 19" tires (255 front and 275 rear). If I go with the new caster camber plates, will I need upper or lower control arms to dial in the pinion??

Tim

  • You should not need new control arms. Though, depending on if the bushings or arms in general are worn, it would be a good idea to eventually replace them.

Will these springs work with a set of 19x10 and 19x11 wheels with Nitto NT555 G2's 285/35/19 Front and 305/35/19 Rear? If not, would it be a better bet to get the pros instead of the sportline or a different brand like BMR? Also, will the Koni Yellows be a good mate with these springs or is there a more compatible option?

Stunttumbler

  • The sportlines would be pushing your clearance with these sizes on your car. A safe bet to go with would be the pro-kit or the BMR springs yes! Either way they would mate with the Koni yellows just fine!

Ok I've got a set of Shelby cs1 wheels and I'd like to know of this kit would work. Ill be running 295/30/20 tires on the 20x11 rears. Also I'm running a turbo kit and the wastegate hangs low, has anyone seen any of these issues

JonathanW

  • The Eibach Sportline Spring Kit should not have issues with clearance with the wheels and tires you described. When it comes to clearance for your wastegate, we recommend measuring ground clearance with the waste gate at stock ride height, and removing 2" from this measurement to see if this will still have adequate clearance, as every turbo kit is different and on some, even installation can vary enough to change clearances like this.

Will these springs work well with gt500 strus and shocks. What shock / strut combo do you guys recommend

JonathanW

  • The Eibach Sportline Spring Kit can be used with GT500 Shocks/Struts, but it is recommended to step up to an aftermarket shock/strut such as Koni, Bilstein, or Eibach due to the aggressive drop of these springs to ensure the best ride and handling, as well as preventing premature failure of shocks/struts.

    Sportline Springs from Eibach

    I've had these from allmost the begining and at every show at least two or more people will ask me how the car can sit so low and "race like". I use 0.5 degrees negative camber, otherwise you will have to much and your car will look like a Honda civic !!! Look at my Grabber Orange GT and judge for yourself. I also use Eibach 20mm wheel spacers on my factory rims with tire size front to rear of 255/45-18 to 285/40-18. Killer !! All parts including Nitto tires are from AM.com , great servise.

    Ive been lookn at every type of spring, and hight combo for months now...reading all the neg. and poss. of them all. For me, if im gonna spend the money, id rather have a noticeable difference. well, I achieved that goal! these springs are perfect. I replaced the rear shocks and I gotta say, it doenst ride bad at all! reading some of these blogs about how rough the ride was, I hesitated for a bit...but now that they are in my own car...I gotta say those people should NOT be driving a mustang. Had a shop friend do the install (with shocks, and all new brakes) in 3hrs with an alignment. I would highly recommend these to anyone wondering if they are too low or too rough. If you want the even stance of the car instead of the rear being up in the air...GET THESE! after thousands of dollars spent w A.M. these springs continue to keep me coming back every time I want a mod. THANKS AGAIN AMERICAN MUSCLE!

    NOT too stiff...!!!

    I based my purchase of the guy who stated... "if you think these spring's ride too rough then , you probably should'nt be drivin' a Mustang"... I changed em over with NO drama, NO camber Plates and NO camber Bolt's (which I bought JUST in case)... when a suspension is lowered, it's usually for better handling and more camber equal's better steering response but, even with the 1.6' drop it BARELY add's any camber...!!! For you "Shade Tree" folk's, I only added a QAURTER TURN of "toe out" to each side and it handle's like a DAH-REEEEEEAM and I HIGHLY recommend these spring's... buyin' a second set for my daughter's TOO...!!!

    LOW!

    I put the rears on in less than an hour with some help and the fronts took about an hour exact. It looks great this low but it does bottom out a lot so you will have to consider your ride height when entering parking lots and driveways. As far as ride quality goes, it's rougher than stock. If you wanted a smoother ride you could upgrade other suspension components. Don't get me wrong though, it's worth it and it doesn't ride like a go-cart. lol

    If it could go wrong, it did. Not the parts fault, just my car was fighting me all the way. First things first... If you have a vert be prepared to remove the rear support brace. Took about 4 to 5 hours... End result, well worth it. Well worth the time, effort and cost. Shopped, and researched for well over 6 months... Glad I went with the sportlines...

    AWESOME Appearance and Ride

    Products installed: EIBACH Sportline Spring kit and J-M Caster/Camber Plate kit. Installation instructions from EIBACH and J-M were spot-on and made the installation easy. Performed the installation by myself with the tools recommended by AM. The hardest part of the process was getting the spring compressors in the best position to remove the OEM rear springs. Installation of the rear EIBACH springs was a piece of cake. Installation of the front springs and caster/camber plates following the instructions was smooth and easy. Once the installation was completed...the difference in ride height and stance was incredible! Handling is solid and firm and ride quality is awesome! Every where we go here in Germany, our "Pony" turns heads and people stare and point at the car. My colleagues and friends say the car looks amazing with the 20" Foose Legend wheels and the lowered stance. Thanks to American Muscle for helping to make our 'Stang a head-turner and pure fun to drive! Check out the pics and see for yourself!!!

    Roughest car I've ever driven

    I'm not really sure what I expected going into this... certainly not a broken spine every time I hit a bump, but that's what I got! I love the more aggressive look the drop gives to my '08 GT, so it's definitely worth it. I can hardly notice any body roll while cornering now, however there is noticeably more understeer. I guess I need grippier tires on the front to get the best use out of them.

    No more 4x4 look!

    Talked to at least a dozen people about what springs to get for lowering my 2007 Mustang Gt. Had a tough time choosing between the Steeda's and the Eibach's. As you can see , chose the Eibach Sportline, because of the reputation and the feedback from previous people who had them on their Mustangs and loved them. Stance is perfect and ride is good on good roads, noticeably firmer on marginal to bad roads, but acceptable considering what I wanted to accomplish in handling and looks. Easy install, even includes new bumpstops. Dropped the car 2 inches rear, 1.5 front.

    Awesome Springs, Nice Drop, But be careful..

    I believe that mustangs desperately need to be lowered with their massive amount of wheel gap from the factory so I bought these springs which was the lowest drop I could find for springs alone and it lowered a good aggressive amount and looks great! The handling has significantly increased and feels awesome in the road. However, I am about to purchase a new set of tires and wanted an extremely wide rear tire, but now I can't buy them too wide cause they will now rub the edge of the fender so I don't know I guess that's a negative about them but not really the springs fault so I can't really complain
