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.

Perfect height!

I installed my 20 inch Lorenzo's a few days ago, but the Stang needed a finishing touch. These Eibach lowering springs were the perfect addition to keep her from looking like a 4x4! Highly recommended ...

camber plates do i need to buy camber plates with these springs or is it ok is i get these springs and everything is stock?

mystang99

  • Only items you will definitely NEED will be the springs, and a pan hard bar. Camber varies from car to car, I've read some people that got the pro kit springs and needed camber plates but I've also read people with sportlines that didn't need any camber adjustment. Also, if the camber plates are too much money for you, there is always the camber bolts for around 26$ and they should do the trick for you! Also, an adjustable upper control arm will help adjust your pinion angle due to how low the drop is!

hi i have a mustang gt 2005 and i was wondering what are the best springs i can buy because i want my car lower but i want it to ride normal too, i have 20inch rims i wanted to look good

mustangGT2005

  • These r just about the best springs for the price ride and overall quality but replace your factory shocks and struts with aftermarket one for the best ride possible u will loose some ride quality but not much with the shocks and struts

Can I add 20" wheels with these springs? I currently have the stock wheels on the car, but I plan on getting 20" wheels next year. Will the 2" drop in the rear be too much later for the 20's. Thanks any help would be greatly appreciated.

Will this effect pinion angle significantly? Will i need to buy adjustable Upper control arms to fix the pinion angle, or is the effect not enough to cause problems?

Robear192

  • With this big of a drop, you should be adjusting your pinion angle. Your acceleration and driveshaft may change without the adjustment as the angle will be too off. Either an adjustable upper control arm or two lower adjustable control arms will do the trick.

    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.

    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.

    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.

    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!

    This is a must for your S197 coupled with some 19 inch wheels. I love the look with all most no fender / wheel gap and with my 19 chrome billets...MAN FREAKING SWEET! Off the line it seems as my car is faster as there is no lag. I love these!!! The ride is a lot stiffer which to me if fine.

    SICK!!

    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...!!! Thanx AGAIN "AM" for excellent service...!!!

    I was so impressed with the stance of my mustang after install. She's a little stiffer but not that bad. If u have a 2010 make sure u have deep well metric sockets and a long pry bar other than that u don't need to b a shop monkey to install. Took me about 3 1/2 to 4 1/2 hrs. Drop was 1.5 front and bout 2 rear, looks mean as he**!!!!

    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.

    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
