    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.

    5 Top Rated Questions

    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??

    • While driveline vibration issues are not common, it is not a bad idea to correct pinion angle with an upper control arm to prevent unnecessary wear, as well as to prevent the possibility of driveline vibrations.

    Helpful (1)

    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??

    • 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.

    Helpful (1)

    Have a 2007 Mustang gt I have 255’s up front and 305 40 X 18 in the back, will it rub?

    • With a 2 inch drop in the rear, the 305/40R18 will be very close with a chance of rubbing. Honestly for a 305 tire, I would recommend not going more than a 1.5 inch drop as this generally will prevent any issues with rubbing.

    I have a 2006 gt with 18x10 rear 295 and 18x9 255 front will i rub

    • This can honestly depend on if the vehicle is lowered or not. On a stock height 06 Mustang GT, there should not be any rubbing issues with the 295s in the rear.

    Will i rub if i get these , 295/35/20 on the rear and with 255/40/20 in the front , thanks.

    • No, you should not experience any clearance issues with these lowering springs and the tire sizes you are looking to run. However, we wouldrecommend test fitting to be sure.

      Should have bought the Proline kit. Driveways small potholes just about anything you travel over bottoms out. Looks great but just needs to be up about 1/2 inch. No instructions included. Includes 4 bump stops. I fugured out one set goes on the rear end axle but not sure where the other set goes. Keep the Stock shock covers the ones that come with the kit are very light plastic.

      Eibach Sportline Spring Kit (05-10 GT)

      Springs helped the car greatly. Back end is just fine. Even though the front end looks wicked, these springs lowered the front end too much and I was scraping over speedbumps, potholes, etc. So I took it back to the shop and had the original front springs put back on after trimming them down a little. Now the car is basically level and the gap between front tires and fender pretty much matches the gap in the back end.

      Love the Sportlines!

      After obsessing through dozens of forums/reviews, put on Eibachs Sportlines for my 07 GT. They look great in orange coincidentally matching the Koni orange STR.T shocks and struts also available at AM I did at the same time. Good instructions, comes with new shorter bump stops at the rear spring. My goal was to visually lower for best reducing wheel fender gap and add better firmer handling in cornering. These are the lowest and the most level springs without going to the stiffer even lower HandR's. Still slightly raked but a very decent balanced looking drop. Huge difference looks a million times better. The ride.. I've read many times these are jarring or too stiff for some people. Don't be shy, if your a true driver and sporty cornering or race inspired corner addict or just want the look, these are ticket for splitting daily driver and track day. Yes nicely very firm maybe a little jarring occasionally over railroad tracks or man hole covers, but honestly they are not too stiff at all, retaining just enough compression comfort zone for city driving with some patchy roads, they're not annoying if you slow down or avoid obvious harsh road spots. Accelerating hard almost zero squat or front end lift, you can now feel seemingly power going to the wheels instead of the sloppy boat feel. Snap corners at 30mph little or zero body role on stock sway bars. Haven't tried highsiees corner yet. Freeway feels planted and firm, there's more of an "in touch with the road" feel at the wheel. A few moments I found myself wishing they were even stiffer, but probably glad they aren't haa! Car is way more fun to drive. At bare minimum get the adjustable caster camber plates and adjustable rear panhard bar. Rear end will shift over to the left at least an inch with this drop and must be adjusted back to center. I added taller balljoints and bumpsteer kit, but jury is still out on bump steer kit being necessary.

      Installation is something you can do yourself. Just take your time and follow the instructions. You will need the Camber bolt so go ahead and get it now. Oh and a panhard bar, you will need it also so go ahead and pick one up too. I went with the BMR, nice heavy bar with a single nut adjuster.

      Installation was roughly 3 hours using air tools and Jack stands. Very straight forward installation. Fitment is great quality. Ride height and stiffness is a night and day difference. Highly recommend these springs. Also recommend an adjustable panhard bar if you're buying these. My rear axle shifted to the driverside about an inch. I went with the BMR Double Adjustable DOM Panhard bar. It's color matches the springs. Like these springs, it is reasonably priced.
