Description
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 stock 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.

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 ...

If I was to buy these would I need to replace the stock shocks and struts because of the depth of the drop?

Would these work on 94-98 V6? I know if they do the drop wont be as big but if they work the drop should still be over an inch. Right?

  • Oh yeah well over an inch! worth the buy for sure!

would these work on 2000 GT convertible ? if it fits for V6 convertible wouldnt it fit for v8 convertible ?

bamplaya32 Year: 2000 Model: GT

  • The spring rate with these springs are designed the hold the weight of the listed year and models to obtain the 1.7" front and 1.5" rear drop. You should stick with springs designed for the V8 convertibles for your 2000. I've attached the Eibach Pro-Kit below so you can take a look. It's a very similar kit, offers great handling and daily driving characteristics as it's also a progressive rate spring, but will hold the weight of your car much better than this Sportline set. Hope this helps!

    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!!!!!!!!!!!!

    GET THESE SPRINGS!

    Want a BADASS looking pony? Get these springs. Pictures do not do this product justice, as I'm sure every owner will attest. If you are looking to give your mustang a conservative 'slammed' look without running into clearance issues, these are for you. A serious improvement in ride over stock. I rarely got second looks on my redheaded stepchild SN-95, now everyone wants to talk. It's that big of a difference. Don't second guess yourself like I was, well worth $250, especially when hotrod shops want $350 ... Thank you American Muscle, I will be a customer for life.

    Amazing

    These springs got rid of that ugly 4x4 stance stock sn95s have and made it look low and mean. although you have to take speed bumps with care the handing it so much. well worth the money

    Highly recommend

    Installed in about 2 1/2 hours with the help of a friend. Ran into no problems. Springs fit perfect. I do recommend buying the isolaters as mine were dry rotted. I got exactly 2" of drop right off the jack. Filled up with gas right after and it dropped even more with a full tank. Ride is fine. I can tell a little stiffer when hitting bumps but the overall ride wasn't changed. Great springs!

    (Un)settling Springs

    I bought these springs elsewhere because I didnt want to wait for them to ship and we installed them within a few hours. the install was simple as can be and the outcome was id say a 50/50. The rear end dropped right away and we were thrilled with what we saw. However the front has yet to "settle" and sits maybe a 1/2" below stock ride height. We installed these a month ago and I daily my car and have put hundreds of miles on since the install. The iso's are out so that it at least looks a little lower. Overall i think im going to have to cut them in order to get them closer to where they are supposed to be... Im on the fence to recommending them or not
