Description
Performance Handling. These Eibach Pro-Kit Progressive Rate Springs will lower your Mustang's center of gravity, reducing body roll in the turns, squat during acceleration, and excessive nose-dive under hard braking. A set of Eibach Springs are great for daily driving, street, and even track use. Classic Muscular Stance. Not only does a set of Eibach Pro Kit Springs improve the handling performance of your Mustang, but they also improve it's overall appearance by lowering the ride height to eliminate the huge tire to fender gap, for a classic muscular stance.
  • Lowers 2003-2004 Coupe: Front - 1.0”, Rear - 1.4”
  • Lowers 2003-2004 Convertible: Front - 1.0”, Rear - 1.4”


Progressive Design. Eibach's proprietary progressive spring design provides the ultimate balance to deliver aggressive good looks and high performance handling, without ever 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.

Application. This set of four Eibach Pro Springs are specifically designed for use on both the coupe and convertible 2003 to 2004 SVT Cobra with independent rear suspension (IRS).

Great ride/ lower than I thought.

The install of the Eibach pro-kit was very straight forward, if you follow the instructions you will not have any issues at all. The car did drop more than I had thought, however, it is a spot on "stance"

The stance of my cobra looks a whole lot meaner and the ride is also comfortable. Highly recommend anyone who desires a nice clean look with a comfort feel when driving. The cobra seems to handle better

    Great ride/ lower than I thought.

    March 31, 2011

    The install of the Eibach pro-kit was very straight forward, if you follow the instructions you will not have any issues at all. The car did drop more than I had thought, however, it is a spot on "stance" and looks great! If you have a vert watch the brace that sits lowest on your car, this is the lowest point and it is very low.

    Awesome product, easy to install and gives the car just the look I was after. The ride is so much better than stock with these springs installed and the car responds quicker to very little steering input. Thanks Eibach Engineers!

    Lowering_kit_on_IRS_suspension_Cobra

    April 27, 2012

    This kit goes on really easily and the springs fit nearly perfectly in the factory position on the front and rear. The front took a couple of hours not rushing the job. The rear on the IRS looks complicated, but a total of 6 bolts and a floor jack under the differential and the springs will literally fall out. Assistance on the reinstallation would be a plus, but if you carefully jack up the IRS assembly to just the right clearance the springs will stay in place and you can jack up the IRS to re align the bolts and in less than an hour the rear will be done. The ride is very solid and the lowered look is just about perfect. The ride is very nice for daily street driving and I cant wait to run it on the 3.7 mile course in Sebring for a track day for a real test. I added the D spec Tokico shocks and the Eibach anti roll bar kit too, a nice combination and I highly recommend it !

    Awesome looks and easy install

    April 02, 2012

    I bought the Eibach Pro-Kit and installed it tonight. Anyone who buys this kit needs to follow the instructions for installing the H&R race springs because it is spot on. I have a shop, but not a hoist, I used floor jacks just like the instructions said. It took exactly 2 hours and 11 minutes. That included re-installing the wheels and roughly 4 beers. Right after install I measured a drop of 3/4" in the front and 1 1/4" in the rear although it will likely settle some more. Anyone looking to lower their Cobra should consider these springs.

    Eibach pro springs!

    November 22, 2013

    The springs are amazing. It didn't give the slammed look but definitely gave it a more aggressive look. Handling is awesome and the ride couldn't be better. Recently took my bottom isolators out of front and rear to drop it a little more. Doing this generally gives it around 1/4 drop
