Complete Guide to Suspension Parts for 2016 Mustang: Upgrades & Replacements

The 2016 Ford Mustang, part of the S550 generation, offers a modern independent rear suspension and a refined front setup. Whether you’re looking to restore worn components or upgrade for better performance, choosing the right suspension parts is crucial. This guide covers the key components—struts, shocks, springs, sway bars, control arms, and bushings—with practical advice for your S550. We’ll help you understand what each part does, when to replace or upgrade, and what to consider for your driving style.

Understanding the 2016 Mustang Suspension System

The S550 Mustang uses a MacPherson strut front suspension and an independent rear suspension with a multi-link setup. This design improves ride quality and handling over previous generations. Key components include:

• Front struts – combined spring and shock unit, also called a coilover assembly.
• Rear shocks – separate from the springs, mounted to the lower control arm and body.
• Coil springs – support vehicle weight and absorb bumps.
• Sway bars (stabilizer bars) – reduce body roll during cornering.
• Control arms – connect the wheel hub to the chassis, controlling wheel motion.
• Bushings and ball joints – allow for articulation while isolating noise and vibration.

When to Replace vs. Upgrade

Replacement is necessary when parts are worn: leaking shocks, sagging springs, loose ball joints, or torn bushings. Typical signs include excessive bounce, uneven tire wear, knocking noises, and poor steering response. For daily drivers, OEM-equivalent parts restore factory comfort and handling.

Upgrading is for enthusiasts seeking better performance—autocross, track days, or spirited street driving. Upgrades can improve cornering grip, reduce body roll, lower ride height, and provide adjustability. Common upgrades include lowering springs, adjustable dampers, thicker sway bars, and polyurethane bushings.

Front Suspension Parts for 2016 Mustang

Front Struts and Coilovers

Front struts are a critical wear item. For a 2016 Mustang, you have three options:

• Factory replacement struts – match OEM performance. Brands like Motorcraft, Monroe, and KYB offer direct-fit units. Cost typically ranges $150–$300 per pair.
• Performance struts – stiffer valving for reduced dive and better control. Koni Sport (adjustable) and Bilstein B6/B8 are popular. Expect $400–$800 per pair.
• Coilover kits – combine spring and damper in one adjustable unit. Full coilovers (e.g., KWV3, Steeda Pro-Action) allow ride height and damping adjustments. Prices start around $1,000 and go up to $3,000+.

For street use, performance struts with your stock springs or mild lowering springs offer a good balance. Coilovers are overkill for daily driving unless you track the car.

Front Springs

Springs determine ride height and stiffness. Factory springs have a moderate rate. Lowering springs (1–1.5 inches) from Eibach, Steeda, or Ford Performance reduce the center of gravity and look aggressive. Keep in mind: lowering may require camber adjustments and can make the ride firmer. Progressive rate springs provide better comfort than linear springs for daily use.

Front Control Arms and Bushings

The S550 Mustang uses forged aluminum front control arms (lower arms). These are durable, but the rubber bushings wear out, causing alignment shifts and clunks. Upgrading to polyurethane bushings or adjustable control arms (e.g., Steeda, BMR) improves steering precision. For most drivers, new OEM bushings or a premium replacement arm (with ball joint) from Moog or AC Delco is sufficient.

Sway Bar (Front)

The front sway bar connects the left and right control arms, resisting roll. A thicker bar (e.g., 32mm vs 28mm stock) increases roll stiffness and reduces understeer. Adjustable bars (like those from Eibach or Hotchkis) let you fine-tune balance. For street use, a 1-step thicker bar with poly bushings is a cost-effective upgrade.

Rear Suspension Parts for 2016 Mustang

Rear Shocks

Unlike many cars, the S550 Mustang separates the rear spring and shock. Shocks mount to the lower control arm and the body. Choices:

• OEM replacement – Monroe or Gabriel. $50–$100 each.
• Performance shocks – Bilstein B6/B8, Koni Sport. $150–$300 each, often adjustable.
• Coilover conversions – some replace the rear shock and spring with a coilover unit (e.g., Viking, QA1). These require additional parts and are more for track use.

Rear Springs

Independent rear suspension (IRS) has separate springs. Lowering springs for the rear are common, but you must maintain proper geometry. Progressive rate springs help avoid bottoming out. For a daily driver, stick with stock or mild lowering (1.0–1.2 inches).

Rear Control Arms

The IRS has multiple control arms: upper, lower, toe links, and knuckle links. Factory parts have rubber bushings that allow compliance. Upgraded adjustable arms (Steeda, BMR, Eibach) allow toe and camber adjustment, crucial after lowering. They also eliminate bushing deflection, improving rear stability during hard cornering. For street driving, simply replacing worn bushings with polyurethane (Energy Suspension) is often enough.

Rear Sway Bar

A thicker rear sway bar (e.g., 24mm vs 20mm stock) reduces body roll and can increase oversteer tendency. Many enthusiasts pair a thicker rear bar with a mild front bar to balance handling. Adjustable end links (Steeda, BMR) allow preload tuning.

Additional Components and Considerations

Bushings and Ball Joints

All suspension pivots have rubber bushings. Over time, they crack and wear. A full bushing kit (like Prothane or Energy Suspension) replaces front lower control arm, rear control arm, and sway bar bushings. This tightens up the feel without the cost of new arms. Ball joints are typically integral to the control arm; replace the whole arm if worn.

Camber Bolts and Plates

Lowering the 2016 Mustang often introduces excessive negative camber in the front. Camber bolts (Moog, Steeda) can adjust front camber within a limited range. For track use, camber plates (like Vorshlag) provide more range and are stronger. Rear camber is adjusted via eccentric bolts or adjustable control arms.

Strut Tower Braces and Chassis Braces

While not strictly suspension, these add bracing to reduce chassis flex. A front strut tower brace (e.g., Steeda, Ford Performance) ties the strut tops together, improving steering response. Rear braces (like the Steeda subframe braces) reduce wheel hop. For daily driving, the effect is subtle; more beneficial for track use.

Choosing the Right Upgrade Path

Budget-Friendly Replacement

If your 2016 Mustang has high mileage (over 80k) and the suspension feels loose, replace worn parts with quality OEM-style components. Recommended: Monroe struts/shocks, Moog control arms, and standard bushings. Cost under $500 for all four corners plus alignment. This restores factory ride quality.

Street Performance Upgrade

For spirited street driving, a combination of lowering springs (1–1.2 inches), performance struts/shocks (Bilstein B6 or Koni Sport), and a thicker rear sway bar greatly improves handling without sacrificing daily comfort. Add poly sway bar bushings. Budget $1,000–$1,500 plus installation.

Track/Competition Setup

For autocross or track days, invest in adjustable coilovers (KWV3, JRZ), adjustable front and rear control arms, camber plates, and a full set of poly bushings. Sway bars should be adjustable. This is a comprehensive setup that allows fine-tuning but costs $3,000+ and requires professional alignment and setup.

Installation Tips and Alignment

Most suspension components require specialized tools (spring compressors, torque wrenches) and jack stands. If you’re not experienced, have a certified shop install them. After any suspension work, get a professional alignment. Specs for the 2016 Mustang include front camber: -1.0° to 0.0°; caster: 5.5° to 6.5°; toe: 0.10° to 0.20° per side. Rear camber: -1.0° to 0.0°; toe: 0.15° to 0.25° per side. Adjustable parts allow optimizing for handling or tire wear.

Final Recommendation

For most 2016 Mustang owners, a practical upgrade path is: start with new performance struts and shocks (e.g., Bilstein B6) and mild lowering springs (Eibach Pro-Kit). Then add a thicker rear sway bar with poly bushings. This combination transforms the car’s attitude— reduced body roll, better turn-in, and a flat cornering stance—while keeping decent ride quality. If you track the car often, step up to adjustable coilovers and control arms. For worn-out stock parts, simply replace with OEM equivalents and enjoy a fresh ride.

Remember to always replace hardware (nuts, bolts) that are single-use, and use proper torque specifications. The 2016 Mustang rewards well-chosen suspension upgrades with a more engaging driving experience. Invest wisely based on your driving style and budget.
