Revolutionary Suspension and Handling
The S550 Mustang generation brought a significant change to the table with its revolutionary suspension system. In 2015, Ford made a pivotal decision by abandoning the Live Rear Axles (LRA) in favor of Independent Rear Suspension (IRS) across all Mustang models. This move marked a significant milestone in the Mustang’s history, as it replaced a design staple that had been in place for over 50 years.
The introduction of IRS was a game-changer for the Mustang, dramatically improving its handling characteristics. With better wheel control, reduced body roll, and an enhanced ride quality, the S550 Mustang outperformed its predecessors, including the track-focused Boss 302 model, without sacrificing its straight-line performance.
Independent Rear Suspension Upgrade
The shift to IRS was not just a change; it was an upgrade that brought the Mustang’s handling to the next level. By allowing for more precise control over the rear wheels, IRS enabled the S550 Mustang to corner more effectively and maintain stability at high speeds.
Track-Ready Performance
The S550 Mustang’s performance capabilities were further enhanced with the introduction of Performance Package options. These packages included larger wheels equipped with sticky summer tires, upgraded brakes, and chassis bracing designed specifically for track use. The pinnacle of track-ready performance was achieved with the Shelby GT350R, which featured carbon fiber wheels, aerodynamic improvements, and track-tuned MagneRide dampers that adapted to changing road conditions in milliseconds.
The S550 generation’s focus on performance and handling cemented the Ford Mustang‘s reputation as a serious contender in the world of racing. With its advanced suspension system and track-ready performance capabilities, the S550 Mustang remains a beloved model among enthusiasts and a benchmark for performance.

Top Modifications for Your S550
S550 Mustang enthusiasts know that modifying their ride is key to unlocking its full potential. With a range of performance upgrades and exterior enhancements available, you can tailor your vehicle to your driving style.
Performance Upgrades
To enhance your S550 Mustang’s performance, consider upgrading its air flow systems. Cold air intakes and high-flow filters can improve engine breathing while producing a more aggressive induction sound. Exhaust upgrades, such as axle-back and cat-back systems, offer improved exhaust flow, weight reduction, and a more aggressive exhaust note.
For substantial power gains, supercharger kits are available for all S550 engine options. These bolt-on systems can add 150-300 horsepower, depending on the engine and supporting modifications. Suspension upgrades, including lowering springs, performance shocks, and sway bars, can dramatically improve handling. Aftermarket wheels and sticky performance tires enhance grip and reduce unsprung weight.
Exterior Enhancements
Exterior modifications can not only improve the Mustang’s appearance but also enhance its aerodynamic performance at higher speeds. Aggressive front splitters, side skirts, rear spoilers, and hood vents are popular options. Upgrading your headlights can improve vision and performance at night, while aggressive bumpers can make your Mustang look more serious.
By incorporating these modifications, you can take your S550 Mustang to the next level, enhancing both its performance and style.
What to Look for When Buying Used
When considering the purchase of a used S550 Mustang, several key factors should be evaluated to ensure a well-informed decision. We will guide you through the essential checks to perform.
Common Issues to Check
Inspecting a used S550 Mustang involves checking for potential issues that could lead to costly repairs. For instance, some early models experienced problems with the air conditioning system and climate control functionality, which are part of the HVAC components. Ensuring these systems are functioning correctly is crucial.
- Verify the air conditioning system is working properly, as repairs can be costly.
- Check the vehicle’s service history to confirm regular maintenance, particularly oil changes, has been performed.
- Inspect the condition of the wheels and tires for signs of aggressive driving or curb damage.
Mileage and Maintenance Considerations
When evaluating a used S550 Mustang, understanding the impact of miles and maintenance history is vital. Many S550 Mustangs were used as weekend cars rather than daily drivers, so a lower-mileage example isn’t necessarily better than a well-maintained higher-mileage car.
It’s also worth noting that modifications can affect the vehicle’s reliability and potentially void any remaining factory warranty. Unless you’re purchasing from a reputable truck or car modification shop, be cautious of heavily modified examples.
- Consider the maintenance history and how the car was used.
- Be wary of heavily modified examples unless you can verify the quality of parts and installation.
By carefully inspecting these aspects, you can make a more informed decision when purchasing a used S550 Mustang.
Price Range and Value
The S550 Mustang offers a compelling blend of performance and value across its range of models. With base EcoBoost models starting around $20,000-$25,000 for used examples with reasonable miles, it makes performance accessible to enthusiasts.
Mustang GT models command a $5,000-$10,000 premium over EcoBoost variants, reflecting their V8 power. Special editions like the Bullitt and California Special carry a 10-15% premium, while rare Heritage Edition models with supercharger packages command higher prices.
The track-focused Shelby GT350 represents the high end, with clean examples ranging from $45,000-$65,000. When comparing the S550 Mustang to competitors, it often provides better value retention, especially for special editions, making it a sound investment for collectors.
Notably, the value proposition extends to the truck market, with Heritage Edition F-150s offering Mustang-inspired performance with utility, albeit at a significant premium over standard models, and without the need for air suspension upgrades.
