    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.

    Would you need to replace the stock shocks/struts with this kit?

    • The Eibach Pro-Kit Lowering Springs will not require new shocks and struts in order for installation but will be a very considerable upgrade. Your original shocks and struts are not manufactures to handle the additional pressure of these lowering springs and will wear over time so upgrading sooner than later will be best.

      Only lowered the car a 1/2 inch, not worth the work involved or the money. Should have bought Ford Performance B springs.

      They ride great! Perfect for crusing around! And they help stop the excesive body roll of the stock springs. Hopefully they perform at the track.

      Eibach pro spring for coupe

      I installed these and the koni strt shock and strut kit. I was nervous that ride quality would plummet and I would hate my car. My car previously had the Bullitt suspension but with 160k miles, it needed replacing. The install took me about 8 hrs to laugh, curse, and toss a couple wrenches, as i had no impact gun or second set of hands. My patience paid off big time with this set up, it's more firm, like a sports car should be. The first impression was "what car is this?". The boat feeling is gone, the look is great. After driving around 30 mins, I headed back home through a 25 mph country twisty road. I thought I was alone, but someone in a blacked out Mercedes got right on my rearview. Unsure of what the outcome would be, I downshifted into 2nd just before the first turn. Mid corner, I left with authority, cautious of the gravel on the road. By the time I entered the next turn, the Mercedes was trying to catch up. I grinned so hard that it hurt. After we were back on a straight road, I just cruised, the suspension took all I threw at it. No tire chirp or body roll. The Mercedes driver was mad as he drove by and he sped off. Buy this kit only if you don't mind a permanent grin.

      Great Product....

      Actually improved ride and handling way more than expected....dropped the car by about 1" which was good enough for me. I purchased front and rear isolators as well and so far so good. Very happy with the overall package and performance without spending a fortune. Wish I had done it long time ago.....Definitely recommend!!!!

      Good Product

      Personally these were what I was looking for. Not a dramatic drop but a nice look for the car. I noticed no difference in the ride compared to stock. The install seems daunting but its really not hard, I recommend researching the install thoroughly before tearing into it. I left my front isolators out and only the bottom isolator in the rear in and I love the look.

      These springs are the ONLY way to go! Improved cornering and launch. And an awesome look! After install the springs take about 8 hours to settle in and gives the car an aggressive stance. Also, very easy install!

      Like stock!

      My 04 ride height is about an inch lower after settling. I notice it, but nobody else can. I didn't want the stiff suspension feel so I went with this pro kit. The car rides like stock due to the progressive spring rates. Also, when installing the rear, they don't tell you that your LCA won't line up with the axle so you have to jack up the front of the diff to align it.

      Great looking perfect drop

      I recommend these to any mustang owner these dropped it perfect and that was right after they got done give em about a solid week to settle oh yeah amazing looking. Ride is good. Now I had to go with these because I have cutouts and longtube headers other wise I'd go with the sportlines but if you don't plan on longtubes or cutouts or anything hang low for exhaust I'd go sportlines now you will suffer ride quality but who cares it's a mustang right lol but other wise go with these great looking Better than stock of course my girlfriend has sportlines on her 98 GT it looks so sick I love it but she don't have longtube headers she has shorty headers so she can go that low lol. Don't expect these to slam it because they won't even settled they won't now sportlines will but these settled look amazing good for me. Definitely get these. Oh rear you can do yourself easy front end do by shop with caster and camber plates. And price idk just call around and check

      Perfect height

      Got these to replace a broken front spring. Fronts are a challenge for one person to install without spring compressor. Lowered ride height is perfect. Suspension feels same or slightly stiffer. I paired these with Koni STR.T shocks.

      Love the ride, may not work for me with wheel tire combo

      I bought these to lower my '91 GT and make it handle better. Installed them with a set of KYB AGX front shocks. Both of these goals were mostly achieved, however, hard bumps, heavy braking, and any turning while moving faster than 15 mph causes tire rub in the front of the car on the top of the arch of the metal fender on both sides. Harder bumps also cause rubbing on the rear fenders. I am running (Front: 245/45 R17x8, Rear: 275/40 R17x9) with 1/2 inch spacers in the rear (to prevent the wheels from rubbing on the rear axle dampers). I put a set of twist in spring stiffeners in the rear and now that doesn't rub but I haven't figured out a solution to the front yet. Different wheels and rolling my fenders are out of the question so I may have to go back to stock springs. So in summary, love the springs but be aware of your wheel tire combo with relation to the amount of lowering.
