What Are Ford S550 Mustang Coilovers?

Coilovers 101

Coilovers replace the factory shocks and struts with height-adjustable shock absorbers paired with springs in a single integrated unit. This provides complete control over the suspension’s ride height, compression/rebound damping, spring rates, and more. Coilovers transform handling by allowing customization of the suspension geometry for your Mustang’s suspension setup and driving style. They open up tuning possibilities that are just not possible with lowering springs or the stock suspension.

Coilovers vs. Standard Suspension: What Sets Them Apart?

Unlike the stock suspension, coilovers allow you to independently adjust ride height, shock stiffness, and spring rates. This means you can slam your Mustang closer to the ground for that neck-breaking stance while retaining a comfortable ride. Corner weight and alignment can be perfectly dialed in for owners who prefer setting their S550 up for track days. Adding a set of custom coilovers opens suspension tuning possibilities far beyond the factory setup. A set of quality coilovers are often the foundation for building the perfect suspension configuration.


The Performance Benefits of S550 Mustang Coilovers

Improved Handling and Durability

Coilovers allow ultra-precise tuning of compression and rebound damping and significantly improve your Mustang’s driving dynamics. This reduces body roll in corners, improves traction, and provides more responsive steering and turn-in compared to stock suspension. You can also adjust each coil-over's settings to tailor the ride quality to your driving style and road conditions. Your Mustang will carve up corners and make your favorite roads even better than before.

The Perfect Suspension Setup

With coilovers, you can slam your Mustang’s ride height for an eye-catching lowered stance. Independent adjustability also means you can have an aggressive ride height while keeping your ride comfortable. For the track, the camber can be increased for sharper handling and weight can be shifted for balanced cornering. Coilovers give you the ability to create your ideal suspension setup for the street and track.

Head-Turning Aesthetics 

Nothing transforms the look of an S550 more than a lowered ride height. A mild 1-2 inch drop enhances your Mustang’s muscular stance while 3 inches or more provide head-turning slammed looks. Lowered ride height complements wider wheels and tires perfectly, making your setup stand out from the crowd. Coilovers make it easy and safe to get the exact look you’re after.


What Makes A Quality S550 Mustang Coilover?

Material and Build Quality

Look for coilovers constructed from high-grade stainless steel and aluminum components. Sealed cartridges and quality internals ensure smooth adjustment and long-term durability for street or track use. Top brands like KW Suspension use inverted shock designs that place the piston at the bottom for improved oil control. We recommend purchasing coilovers that are rigorously engineered to ensure a long service life.


Most adjustable coilovers allow fine-tuning of rebound, compression, and ride height independently. This allows dialing in the perfect balance of handling performance and ride quality. Look for camber plates to help realign suspension geometry at lowered heights. Easy-to-use adjustment knobs are convenient for quick tweaks. More adjustability gives you the ability to dial in your coilover setup.

Custom Spring Rates

Spring rates affect ride quality and handling. Stiffer springs carry more weight and resist compression for improved cornering and control. Softer springs absorb bumps better for a more compliant daily driver. Most coilover manufacturers nowadays offer standard and custom spring rates to match your needs. Understanding these dynamics will help you when choosing the ideal setup. Think carefully about how you want your Mustang to handle and ride and be sure to do some research before pulling the trigger!


How To Install Your Ford S550 Mustang Coilovers

What You Need to Know and Tools Required

Before installing coilovers, be sure to read all instructions thoroughly first. You’ll need basic hand tools like ratchets, sockets, jack stands, and a floor jack. Allow 2-3 hours for DIY installation. A vehicle hoist makes the job significantly easier. Replacement components like camber bolts should be on hand. Don’t forget an alignment is required afterward.

Alignment and Adjustment

After installing your new coilovers, getting an alignment is important to ensure ideal suspension geometry and prevent uneven tire wear. Adjusting ride height and dampers requires careful testing and tuning to match your goals. Take the time to properly dial in rebound, compression, and adjust height to maximize performance, and consider visiting your local race shop if you are unsure about setting up your suspension for track duty.

How To Maintain Your S550 Mustang Coilovers

Routine Maintenance 

Periodically inspect coilovers for damage, leaks, and noise that may indicate issues. Check torque specs and re-tighten components as needed. Keep dirt and debris off shafts and seals. Overall, quality coilovers can last 50,000+ miles with proper maintenance. Some brands also offer rebuild services at a fraction of the cost of a new set, ensuring your Mustang keeps going while keeping your bank account happy.

Common Issues

Clunking noises over bumps can indicate worn bushings or joints needing replacement. Binding or stiff adjustment may mean dirt contamination needs cleaning. Excess oil on shafts indicates worn seals. Strange handling could point to malfunctioning dampers needing a rebuild or replacement. Catching these issues early can prevent further damage from occurring and the potential of a car accident.

Aftermarket Catback Exhaust

Let your Mustang's engine truly roar with an aftermarket exhaust system. From a simple axle-back to a free-flowing catback, an aftermarket exhaust allows your S550's engine to rev freely and breathe easier. With a performance exhaust, you'll feel a rush of power and enjoy the sweet soundtrack of performance.

Performance Air Intake

Complement your free-flowing exhaust with a cold air intake or short ram system that feeds cooler, denser outside air to the engine for better throttle response and exhilarating power gains. Aftermarket intakes remove restrictive components and maximize airflow, adding more power across the board. Choose between an open-element filter or a sealed box design to dress up your engine bay and add some easy power.

Aftermarket Exhaust Headers

Take your Mustang's performance to the next level by replacing the restrictive factory manifolds with a set of tuned long tube headers. Properly designed stainless steel headers reduce turbulence and increase exhaust flow for substantial power gains, especially in the upper RPM range. But proper ECU tuning is a must with Mustang GT headers to realize their full potential.

Frequently Asked Questions (FAQs)


What are the signs that it's time to upgrade to coilovers?

If your Mustang exhibits excessive body roll, nose-dive under braking, inside wheel lift during hard cornering, or has a bouncy uncomfortable ride, it may be time for coilovers. A desire for a lowered stance or tuning potential is also a good reason.

How do coilovers affect the warranty of my Ford Mustang S550?

Aftermarket coilovers themselves typically won't void the factory warranty, but damage or issues arising from their use may not be covered. Lowering beyond a certain amount can void alignment/suspension warranties. Check with your dealer.

Can I install coilovers on my Mustang S550 myself?

With automotive experience and proper tools, advanced DIYers can install coilovers at home in 2-3 hours per axle. But a professional shop with a lift simplifies the process considerably. Both methods usually yield good results.

How often should coilovers be replaced or serviced?

Quality coilovers can last 50,000-75,000 miles or more. Rebuildable high-end models may go 100,000+ miles with proper servicing. Expect 2-5 years of use depending on miles driven and conditions.
