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?

Jackson

  • The Eibach Sportline Spring Kit will fit 20 inch wheels. However fitment will depend on the tire size you add as well.

Will these fit the 99 v6 coupe? If so will it actually lower it? Thanks AM

IsaacScoots

  • Although advertised and designed for the 99 V6 convertible, it will certainly fit the coup as well. The convertibles are heavier than the coups, so the springs will be more stiff than intended, and the Mustang won't drop as much as advertised, due to its lighter weight in comparison.

will these springs fit my 2001 v6 coupe mustang?

NathanD

  • These will bolt up to your car however they will not drop the car as far as they say they will as these springs are meant for the heavier convertible models. We do carry the Eibach pro-kit springs for the coupe V6 models. https://www.americanmuscle.com/eibach-pro-springs-79-04-v6.html

Would these be compatible with my 2000 convertible GT?

RomanD

  • 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

    Simply....awesome.

    These took me and a buddy 2.5 hours to install this morning. The pictures I have submitted are taken immediately after install, so the springs haven't settled yet but you can notice the definitive drop in ride height. I absolutely LOVE it. I'm expecting about another 1/2" drop up front, and maybe 1/4" rear drop over time as the springs settle in. The stance these springs provide is so very appealing to the eyes. I just can't get over the difference these springs make after install, going from the 4x4 look to the aggressive racy look. The ride quality is exactly what I expected. You feel bumps in the road more, but unlike a lot of people, I enjoy the racy feel of the lowered vehicle more than a ride where you don't feel a thing. If I wanted the ride feel of a sedan, I would have bought a Cadillac, not a Mustang. The handling is excellent as well. A lot less(if any) body roll through corners and freeway on/off ramps. I just can't get over the difference these made. 100% absolutely love these springs, the look, the handling and the feel the car has when driving down the road.

    These springs are awesome!!!!!!!!!!!

    The Eibach Springs were an excellent upgrade for my stang. it looks great and handles like a dream. other than feeling just about every bump in the road. these spring are a great choice to up the looks and handling on your car. it took me an hour and a half to do the install but i also had a lift. the install was pretty self explanitory. i do recommend new sping isolators when doin the swap i put polyurethane ones in from PROTHANE and i love it. well worth it!!!!!!!!!!!!

    Nice drop

    These springs provide a substantial drop but more in the front. I previously had H&R sports and now with Eibach sportlines, the back is the same (1.5") and the front is closer to 2" (.5" more than H&R) Overall a good spring but maybe too low in the front as I now worry about hitting my 2 extra quart ATF pan on dips and bumps.

    They look great, not as low as I want still but definitely better than the 4x4 stance of the stock ones lol. The only reason my ride quality isnt the best is becaue its still on stock shocks but other than that these springs are a must

    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.

    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
