Eibach Spring Install
Excited to finally install Eibach springs which was a breeze. Definitely replace isolators if putting new springs. As far as the lowering spring install it was an absolute breeze with now problems. If you have access to a lift it definitely makes things easier. The lowered drop was supposed to be approximately 1.5" on a 2004 but I only dropped 1" a little disappointed but I'm sure once they break in it will be a 1.5" all around.Helpful (3)

The spring are really nice! The only reason i dont give five stars is i thought it would lower me just a little bit more then they did. This is the second set of these springs i have bought for this car. The first set ended up bottoming out, almost, over time. These seem much stronger, (the others were on the car 15 years), as the car with this set has the nice agressive stance, vs being just lowered an inch from the ground.Helpful (3)

Really love the look of my car now and these springs dropped it a good amount. Paired with Eibach pro dampener kit.Helpful (6)

Not much drop
Only lowered the car a 1/2 inch, not worth the work involved or the money. Should have bought Ford Performance B springs.Helpful (10)

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.Helpful (10)

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.Helpful (11)

will these eibach springs fit my V-6 hardtop or only will they fit on a 2004 V-6 convertible
Hi, these Eibach Pro-Kit Springs will only work with 79-04 V8's and 99-04 V6 Convertibles because of the spring rates, we do have a set of springs for 79-04 hardtop V6's Item #47501 Here's the link http://www.americanmuscle.com/eibach-pro-springs-79-04-v6.html
Do these springs work for any other vehicle other than a ford
These do not work with vehicles other than noted on the product listing.
Hi, I've got an 02 V6 Coupe. You recommended to someone else, https://www.americanmuscle.com/eibach-pro-kit-spring-set-79-04-coupe.html .... The Eibach Kit for 4cyl and V6. You've apparently Dropped that Product... Any other suggestions.

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.
I have them on my 2001 V6 3.8 convertible Can put long tube headers on it and not have bottom out issues Thanks
You can put the Eibach Pro-Kit Lowering Springs with long tube headers without the issue of them bottoming out.
Hey Randy, You will still be able to use the stock shocks and struts with out a problem!
Unfortunately we cannot confirm that these springs will fit on a Ford Ranger as these have only been tested on Ford Mustangs.
The Eibach Pro-Kit Springs are designed for the convertible V6's and V8 coupes only.
You will most likely run into rubbing issues with 20" rims and the Eibach Pro-Kit Springs (79-04 V8 Coupe; 99-04 V6 Convertible; Excludes 99-04 Cobra). The biggest wheel that we recommend putting on the 1999 to 2004 body style is an 18" wheel.
No. Springs will not increase your gas mileage.
That is one of the most popular combinations - 315/35-17 and lowering springs. You won't have any rubbing or clearance using that wheel/tire combo and these Pro-Kit Springs. Check out the customer images for some examples - they look awesome!
Yeah they work. Look real nice to. Do yourself a favor and rent a spring compressor and get some bailing wire makes for an easy install
If you have an '03 V6 Convertible, this is the right kit for you. However, if you have an '03 V6 Coupe, you'd need this kit instead: http://www.americanmuscle.com/eibach-pro-springs-79-04-v6.html. You will want to purchase the CC plates to correct your alignment. General rule of thumb, any drop over 1" requires the CC plates to adjust the suspension to the proper toe and camber. Doing so ensures full life of your suspension parts and will prevent uneven and excessive tire wear. I'd also suggest purchasing new polyurethane front and rear spring isolators. They won't crack or dry out like the stock rubber does and they provide a cushion for a quieter ride. You certainly can use your stock shocks and struts without any problems. However, it's recommended to replace them to get the best handling and ride comfort you can while lowering your car. If you'd like some pointers on exactly what parts you want to get with your springs, please give us a call! We can answer any questions you may have and make sure you have the set up you are looking for!
