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.

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

Would these be compatible with my 2000 convertible GT?

  • These springs will bolt on to your car however they are not set up for the weight of your car and will react differently than a coupe model. We do not have the Sportlines for the convertible models but we do have the pro-kit for your car! https://www.americanmuscle.com/eibach-pro-kit-spring-set-94-04-convertible.html

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.

  • These will not work with the 2003 V6 Coupe as the spring rates of this product is specific for the weight of the V8 Coupes and the V6 Convertibles.

will these springs work on a 2001 gt convertible?

Finny19

  • These springs do not work on GT Convertibles. The v8 engine mixed with the convertible is just a little bit too much weigh for these springs to take, so we offer springs specifically designed for GT convertibles.

    I bought these springs for my 2002 gt convertible and it immediately changed the look and feel of the ride! It will take a few days to break but it's totally worth the wait!! A must buy for the look depending on your application no scrapping even with a chin spoiler!

    Hugs corners!

    Finally got rid of the ugly wheel gab with the 2 inch drop for convertible. Also the car handles in corners better with the help of koni racing shocks. Even new gts and genesis coupes and hang with me in corners. And that's what it's all about, the corners.

    Ibach sport line Springs

    To start off with the shipping was fast I got the springs within three days the installation was a breeze I started off by jacking up the rear end with the axles on jackstands took off the swaybar jacked up one control arm loosened and took out the bolt lowered the control alarm and pulled out the spring put the new spring in pigtails facing the driver side Jack the control alarm up put the bolt and lowered and repeated the process on the other side then installed the rear sway bar the front I put the jack stands on the K member in the middle I loosened all my bolts struts spindle Took off the brake caliper loose in the tire rod and sway bar from the top I jacked up the a arm took the bolts out of the strut lowered it down ball joint came out sway bar link came out which drop down the a arms pulled out old my spring put new one in and jacked the A arm back up I put it back together In reverse from what I took it apart repeat on the other side the way The sport lines made my Car look amazing Handling the stability in cornering and breaking is what every mustang should have came with factory with the look alone is worth it and then installation was about three hours with the proper tools

    Need more low!

    I installed these with the Eibach Pro Damper Kit. Took a few days for it to settle, scared me at first because I didn't think it was going to drop. My car sits a little uneven, but not noticable unless you're staring at it over and over. Wish they lowered me a bit more but it looks awesome compared to stock. Car handles like a dream

    Perfect drop do your research

    I kept bouncing back and forth between the sportline and h r super sports, so glad I chose these!!!! The worries about running with or without isolators shouldn't be a concern if you do your research and know what drop you want. Currently im running no isolators in front and only the top isolators in the rear, once it settles I assume another 1/2" in the front but over all no noises or issues! Love eibach and their product.

    Just Wow !

    I installed these because I noticed a crack on my spring, but when I finally removed the old oem ones they broken at the bottom on both sides and to make it worst the polyurethane mounts were melted on to the lower control arm. So I advise buying the new polyurethane mounts. Just in case also bring a flat head screw driver, pressure pliers and a hammer To remove those melted parts. As for the new springs it was night and day. I paired them with the eibach shocks and struts and took a 25mph exit at 55mph hugging the yellow line ! Thanks AM !

    Fantastic Product

    Great product. Makes the car look so much better than before and did not really effect the ride quality. Obviously being a stiffer spring its going to ride a little harder, but not much. Easy install, if you know what you are doing.

    Love the agressive stance!

    Easy to install, made the car drive much better. Love the agressive stance it gave my car. Says they aren't for the 99-04 convertibles but they will work! Not sure why they say they won't maybe the extra body weight of the convertible! Very happy with this purchase have two other mustangs and will be ordering these springs!
