Better Handling. Give your 2005-2010 GT 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 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.

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.

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.

A real improvement over the stock height and handling. They brought the car down a little lower than I expected but I love it! The ride is surprisingly smooth with no bounce...

That stance though

Moderately easy install. Great product. Roughly 2 inch drop in the back and close to 1 1/2 inch in the front. Nice stance, excellent handling combined with a new st brace.

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??

Answer This Question

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.

  • When installing lowering springs, we normally recommend replacing your shocks and struts if they haven't been replaced recently. This would let you keep a good ride quality even after lowering your Mustang. We also recommend installing caster camber plates to keep your alignment within spec. Finally, we recommend installing an adjustable panhard bar to realign your rear axle since the car has been lowered.

Answer This Question

I have a 08 GT with 19" 245 fronts and 275 rear tires. I want to order the Eibach sportline springs and plan to order an adjustable panhard bar at the same time. Will I need new caster-camber plates to properly align the front end??

Tim

Helpful (0)
  • Caster camber plates are possibly needed, bu as it turns out it isn't quite a guarantee. Every Mustang reacts differently and you can actually buy them accordingly if you want to. However, to be fair, chances are you need them and installing them regardless definitely doesn't hurt.

  • The Eibach Sportline Spring Kit - Coupe & Convertible (05-10 GT) will work with the wheels you have on your car. You should have no problem with clearance.

Can these springs be used on a V6 Model as well? I ask because on a mustang forum where a member was outlining how to do a V6 to V8 swap, he said the Eibach springs are interchangeable between models.

  • The Eibach Sportline Spring Kit - Coupe & Convertible (05-10 GT) have a guaranteed fitment for 2005-2010 Mustang GT's, however some modifications can be made. To confirm, give Eibach a call!

    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

    Easy install, perfect look.

    For only $200 this is probably the best bang for your buck. The look alone would be worth it, but ridding the body roll makes this an absolute five star purchase. Install was a breeze absolutely no trouble. I used the install video I found on YouTube which was a walk in the park. If I was in a hurry to get the job done I think start to finish could very easily take under two hours. As for the scraping everyone talks about, I have little to none. Given my tires aren't low profile I do have about an inch or so more clearance than most S197 drivers.

    Exactly level

    The sportlines ended being exactly what I was looking for. They almost completely eliminated the tire gap in the front and rear along with making the car perfectly level. Before install, I had about 1.5" front and 2.5" rear gap. Now I would say there is maybe 1/4" inch in front and rear. Change the compete look of the stance. Have bottomed out a couple times now, so you gotta watch those speed bumps. Ride is slightly rougher, but is worth it. No more roller coaster when getting on the brakes. Ended having to install camber bolts. Negative camber was noticeable right away. Installed the factory strut mounts 180 degrees out, with the arrow pointing outward to gain .5 degree in positive camber right off. Took about 3 hours to install.

    What a difference an inch makes.

    So glad the spring is here! Or shall I say springs. Ordered and received the springs in about 5 days and waited for the weekend to slip them on. I planned a half day to swap the new ones in but was delighted by how fast and easy it all went! Less then 3 hours and it was all done. I love the look and feel of my stang since lowering it. The ride feels about the same but I have noticed the braking nose dives seem to be a thing of the past. The only negative is obviously needing to get a full alignment but no biggie. I will tell you I had no idea there were so many speed bumps and dips around here!!

    The pressure of the front wheels may make some noise while driving the car in unclear street or when you turn the streeting wheel to left or right

    You never get unsatisfied with Eibach, I recommend it because it I'll help you controlling your car way better than the factory sespenssion.

    Wow! Better than I expected.

    We went back and forth between buying the Eibach Pro and Eibach Sportline springs. Talked to local speed shops, looked at pics, etc. Finally decided on the Sportline because we just thought the drop looked better on the cars that we saw pics of. Must say, I can't be happier. The springs were bought as a birthday gift for my 17 yr old son. We immediately had them installed on his 2006 GT at our local shop (cost including alignment and tax $411). The before and after look on this car is dramatic. The springs give it a snug squat on the front end (tire is almost "under" the wheel well) and the rear is barely 2 fingers of play. It has the same flat stance as a GT500, zero rake. The car has stock bullitt style 17" wheels, they fill out the wheel wells nicely and the low stance actually makes them look wider. The car now rides tighter, no body roll on turns and very little noticeable dive and/or squat. The ride is now firmer for sure,,you'll feel more of the road. But this is a sports car, so thats what we want. Over all, for just the appearance alone I'd give these springs top marks. So happy we did it,,,and as always pleased with the customer service and responsiveness of American Muscle.

    easy peezy

    I bought these springs and had a buddy come over to help me with the install. We got the front done in about 2 hours minus the time wasted trying to find a spring compressor since none of the local parts stores had one for rent. MAKE SURE YOU HAVE A STRUT SPRING COMPRESSOR! You won't be able to do the front safely without it. Once we got the front done i realized my jack was too big to get out from under the car so make sure you have something that is low enough should you buy these. The rear is incredibly easy, all you have to do is set the car on jackstands on the body and take your sway bar and shocks off and push on the axle and your rear spring will come out. The new spring is so short that you can push it up into it's place and still have room, just make sure you keep pressure on the rear end or else you will break something. When it was all said and done i pulled the car out and took a good look at a picture from before the drop and what it looked like now and it is beautiful. If you want an affordable and good looking drop then these are for you.

    Great Buy!!

    I did my research on quite a few different springs and kept coming back to these. And, boy am I glad I chose these ones! It took about two and a half hours (including a couple breaks) for me to install these, along with an SR adjustable panhard bar. This was all done in my driveway with basic power tools. I also rented a strut spring compressor from the local auto parts store. If you don't have a compressor or any pneumatic tools, an electric impact works great too. Just out of curiosity, I watched the video that AM provided for installation of aftermarket springs when I was finished and they do a great job of explaining everything. Even if you're not all that mechanically inclined, it's a lot easier than you might think. Even at home without a lift! The rears took me about 15 minutes. It was adjusting the panhard bar that took the longest time because I wanted everything to be perfect. It takes away that 4x4 look and makes it look like the mean pony it is! Now for the ride quality. I'm not one that's just in it for the looks, but it is a MAJOR plus! The handling has improved tremendously (even with the stock shocks/struts, which I still have on). I do a fair amount of mountain driving on the weekends and the difference is quite amazing. The body roll has decreased immensly, and it feels like it is on rails compared to stock. Yes, it will be more of a rough ride, but what do you expect? If you want the slammed look and for your mustang to ride like a Cadillac then you're in the wrong place, OR you might as well fork over the dough for airbags (which isn't exactly my cup of tea). You will definitely have to be weary about the bumps you take, but that is to be expected. Money well spent! I would definitely recommend these to anyone that wants to improve the handling and looks of their mustang!!

    Best Mod I've Bought!!

    I bought these springs for my 2010 GT and am so glad I did! The change in looks alone was worth every penny and the improved handling is a plus. Now my Stang looks very aggressive and like the muscle car it is. I have received countless compliments and of course that just makes it even more worthwhile. I was slightly hesitant at first as I had lowered my 08 Gt and the ride really suffered. But not with these! I can not tell a difference from the stock ride other than now i have to be more careful over speed bumps (go slower) but that is a small trade off to the way my ride looks and handles. I had a shop install mine for around $460 but I'm sure if you have the correct hardware and knowledge it can be done by yourself at home. Bottom line is I freaking love this mod and am so glad I purchased it! AM rocks!!

    Riding Low

    This Eibach lowering kit is awesome! i did alot of research before making my final decision on this kit. alot of people said that the ride quality wasnt that great but my opinion was that if you cant handle the rough ride for improved handleing you probably shouldnt be driving a sports car. but the way my car handles now is amazing, no more sag or lunge when going through the gears and it just feels like the power is going to the ground. the installation went very easy about 2 hours for the front and 30 minutes for the back all doing it in my garage with the required hand tools. my only bad note was that i wish AM was offering a kit that was a little bit lower. but overall great product and i will continue to do business with AM!
