One of the most popular mods that every S550 Mustang owner is looking for is a good set of performance lowering springs. With so many options available, it can be difficult finding the perfect drop for your Mustang GT, Mustang Ecoboost, Bullitt, or V6 (Coupe & Convertible kits available). As the S550 Mustang experts, we are here at LMR, we have broken down each 2015 to present S550 Mustang's best-lowering spring kit we offer and give you all of the details you want to know.
All specs are taken from the manufacturer's site. Actual ride height differences will vary from car to car, and springs will settle after a few weeks of driving.
S550 Mustang Lowering Spring Guide
Starting at number one are the SVE Lowering Springs! One of the first things you may notice from the factory is that your S550 sits a tad higher in the front than the rear. The easiest way to solve this problem is to go with a set of our SVE progressive springs! Not only will you reduce the center of gravity and body roll of your car, but you’ll enjoy daily driving. When you do lower your S550, it’ll reduce the squat during acceleration and excessive nose-dive during hard braking.
This is the perfect suspension kit when driving on the street or the track. These springs will close that wheel gap while also providing a level stance for your Mustang. The progressive rate in these springs will provide an excellent ride quality similar to OEM quality.

ABOUT THE BRAND
Eibach makes the most nuanced performance suspension products in the world for your Mustang or Ford Lightning. When other suspension components sag, wear out or create sloppy handling or a bone-crushing ride, top street tuners—like top race teams, from F1 to WRC, from Le Mans to NASCAR—inevitably turn to Eibach.
Eibach integrates the same technology in their street springs as in their legendary race springs. Eibach uses the world´s finest Hi-Ten spring steel, produced to exceedingly precise tolerances. Eibach uses world-renowned German CNC coilers, as well as many unique machines engineered and built specifically by Eibach—simply state-of-the-art technology in every step of the manufacturing process.
At number three is the one and only Ford Performance. With the Ford Performance quality, Ford Performance gives your S550 the most when lowering your car. These springs lower your EcoBoost, 5.0, GT350, or Bullitt to get rid of that awful fender gap and increase the handling. As one of the most popular brands in Ford Motorsports, Ford Performance offers some of the best-lowering springs available for your S550 Mustang.

Frequently Asked Questions
How Do I Lower My S550 Mustang?
Lowering your S550 doesn’t take a specialist. Yes, it will take some time, but even a new S550 owner with some knowledge can get the job done! Here’s a list of parts that you’ll need (excluding the lowering springs that you just purchased):
Jack and Jack Stands (Lift accessibility if possible)
18mm Socket (Deep & shallow)

Spring Compressor
Door Panel Removal Tool
Hammer
If you’re ready to start the installation, check out our step-by-step video and article installation guide!
Are Lowering Springs Worth It On An S550 Ford Mustang?
100% yes, they are! This is one of the best low-budget and high-performance mods you can do when getting started on your build. Not only will your S550 look better, but the grip and suspension response you’ll receive will benefit you when driving! Nobody likes wheel gap, so take the opportunity to make the change and make your S550 a beast today!
Will Lowering Springs Affect Ride Quality?
In a sense, yes, your ride quality will be affected. When you retain your OEM struts and lower your ride, your car will be more rigid and less smooth, and you’ll sense most bumps. However, the tradeoff is a more aggressive stance and a better grip.
These Mustang lowering springs fit Ford Mustang GT, V6, Shelby GT500, Bullitt, etc.
