1. Ford Performance M-5300-W Track Handling Pack: Best Track Handling
The Ford Performance Track Handling Pack is a comprehensive kit that includes lowering springs, specially valved dampers, and larger sway bars. Based on owner feedback and the spec sheets, it delivers a sharp reduction in body roll and improved steering response while maintaining a compliant ride for daily use. We appreciated the direct engineering support from Ford, which ensures parts are tested to meet safety standards.
However, this kit is not for those seeking extreme lowering or adjustable damping. The fixed drop of about 1 inch may not satisfy track enthusiasts who want coilover adjustability. If you want a simple, reliable upgrade that works out of the box, this is a top choice, but serious racers should look elsewhere.
- Engineered by Ford Performance for 2011-2014 Mustang GT
- Includes matched dampers, springs, and sway bars for balanced handling
- Reduces body roll and improves cornering grip significantly
Pros: Factory-engineered system with warranty; Noticeable handling improvement without harshness
Cons: Premium price point
2. Bilstein 5100 Series Shock and Strut Set: Best Value Upgrade
The Bilstein 5100 set replaces the factory shocks and struts with monotube gas-charged units that provide better control and stability. In our evaluation of owner reviews and manufacturer data, these dampers offer a significant upgrade in handling without breaking the bank. They reduce float and improve steering feel, making the Mustang more confidence-inspiring in corners.
That said, the 5100s are not adjustable and can be firmer than some drivers prefer on uneven pavement. If you want a simple, durable shock upgrade for daily driving and occasional spirited driving, this is a solid choice. But if you need adjustability or a softer ride, consider other options.
- Monotube design for consistent damping and heat dissipation
- Improves control over bumps and reduces nose dive under braking
- Long-lasting build quality with corrosion-resistant coating
Pros: Excellent durability for the price; Noticeable improvement over stock dampers
Cons: No ride height adjustment; Stiffer than stock on rough roads
3. Eibach Pro-Kit Lowering Springs: Best Lowering Springs
Eibach Pro-Kit springs are a popular choice for Mustang owners seeking a moderate drop and better handling. Our research shows they reduce body roll and give the car a more aggressive stance while retaining acceptable comfort for daily driving. The progressive rate helps absorb small bumps better than linear springs.
The main drawback is that these springs are often used with factory dampers, which can lead to a bouncy ride and reduced damper life. We recommend pairing them with aftermarket shocks for best results. If you want a simple spring upgrade and are willing to replace dampers later, this is a good value, but those seeking maximum adjustability should consider coilovers.
- Progressive rate design for improved ride comfort and reduced body roll
- Lowers center of gravity for better cornering stability
- Compatible with factory dampers, but best with upgraded shocks
Pros: Affordable way to improve looks and handling; Progressive springs maintain decent ride quality
Cons: May cause premature wear on stock dampers; Not as aggressive as coilovers
4. KW Variant 3 Coilover Kit: Premium Adjustable
The KW Variant 3 coilover kit offers the highest level of adjustability with separate rebound and compression settings. Based on manufacturer specs and owner feedback, these coilovers provide exceptional control on track days while remaining civil on the street when dialed in correctly. The stainless steel bodies ensure longevity even in harsh climates.
However, this system is expensive and may be overkill for drivers who only want a mild drop. Setting up the dampers properly takes time and expertise, and a poor setup can ruin the experience. If you are a serious enthusiast who values precise handling and is willing to invest in professional tuning, the KW V3 is a top-tier choice. For most daily drivers, a simpler kit may be more appropriate.
- Independent adjustment of rebound and compression damping
- Stainless steel construction resists corrosion
- TUV certified for safety and quality
Pros: Excellent damping adjustability for fine-tuning; High-quality materials and build
Cons: High cost; Requires professional installation and setup
5. Steeda Sport Progressive Springs: Best for Daily Driving
Steeda’s Sport Progressive Springs aim to enhance the daily driving experience by reducing body roll and improving stability while maintaining a compliant ride. Our analysis of owner reviews indicates that these springs offer a subtle improvement that most drivers will appreciate without the harshness of some sportier setups. They are a great first step for those new to suspension modifications.
That said, these springs are not designed for aggressive track driving. The progressive rate can feel soft during hard cornering, and the drop is modest. If you want a firm, race-ready suspension, look elsewhere. But for a comfortable daily driver with a touch of sportiness, these springs are a solid choice.
- Designed for improved ride comfort and reduced nose dive
- Lower center of gravity without sacrificing daily usability
- Direct fit with no modifications required
Pros: Noticeable improvement in ride quality over stock; Easy installation
Cons: Less aggressive than other options; Not ideal for track use
6. BC Racing BR Series Coilovers: Budget Coilover
BC Racing BR Series coilovers offer a budget-friendly way to get full height and damping adjustability. Owner feedback suggests they provide a noticeable handling improvement and allow for a custom stance. The 30-way damping adjustment gives flexibility to dial in the ride to some extent.
However, the ride quality is often reported as firm, especially at lower damping settings, and the build quality is not on par with premium brands. In areas with road salt, corrosion can be an issue. If you are on a tight budget and want adjustability for street and occasional autocross, these are a decent option. But for long-term durability and comfort, consider saving for a higher-end kit.
- Ride height adjustable with 30 levels of damping
- Pillowball upper mounts for precise steering
- Affordable entry into coilover adjustability
Pros: Great value for adjustable coilovers; Good for stance and mild performance
Cons: Ride quality can be harsh on rough roads; Durability concerns in harsh climates
7. Roush Performance Stage 2 Suspension Kit: Complete Handling Kit
The Roush Stage 2 kit is a complete suspension package that includes springs, dampers, and sway bars, all tuned specifically for the 2014 Mustang GT. According to manufacturer data and owner reviews, this kit delivers a noticeable improvement in cornering grip and steering response while retaining a reasonable ride quality for daily use. It is a popular choice for those who want a turnkey upgrade without the complexity of coilovers.
The main limitation is the lack of adjustability. What you get is what you get, and some drivers may find the ride too firm or the drop insufficient. If you prefer a set-it-and-forget-it solution from a reputable brand, the Roush kit is excellent. But if you want to fine-tune your setup, a coilover system would be more suitable.
- Roush-engineered system with matched components
- Includes front and rear sway bars for reduced body roll
- Vehicle-specific tuning for balanced handling
Pros: Comprehensive kit with proven performance; Good balance between comfort and control
Cons: Limited adjustability; Premium price for a non-adjustable system
Frequently Asked Questions
Will lowering springs damage my factory shocks?
Lowering springs can cause premature wear on factory shocks because they often have different spring rates and ride heights than the dampers were designed for. Many owners report that stock dampers become bouncy or leak after installing lowering springs. It is recommended to upgrade to aftermarket dampers designed for lowered springs to ensure proper damping and longevity.
What is the best suspension for daily driving on a 2014 Mustang GT?
For daily driving, the Steeda Sport Progressive Springs or the Bilstein 5100 shocks and struts are excellent choices. They improve handling without making the ride too harsh. The Ford Performance Track Handling Pack also offers a good balance if you want a more sporty feel. Avoid overly stiff coilovers if comfort is a priority.
Do I need a camber kit when lowering my Mustang?
Lowering a 2014 Mustang GT typically increases negative camber, which can improve cornering but may cause uneven tire wear. Most aftermarket suspension kits include some adjustability, but a dedicated camber kit is often recommended for precise alignment. Many owners install adjustable camber bolts or plates to dial in alignment specs.
How much does it cost to install a suspension kit?
Installation costs vary depending on the kit and shop. A spring swap can cost between $300 and $600, while a full coilover installation may run $500 to $1000 or more. Prices also depend on whether you need an alignment afterward. We recommend getting quotes from multiple shops and factoring in the cost of alignment.
Can I install the suspension myself?
If you have mechanical experience and proper tools (spring compressors, jack stands, torque wrench), you can install springs or coilovers yourself. However, for safety and proper adjustment, many owners choose professional installation. Incorrect installation can lead to poor handling or dangerous failure. Always refer to the manufacturer’s instructions.
Our Verdict
Our top pick for the best suspension for a 2014 Mustang GT is the Ford Performance M-5300-W Track Handling Pack, offering a complete, balanced upgrade with OEM-level engineering. For those seeking the best value, the Bilstein 5100 Series shocks and struts provide excellent durability and handling improvement at a reasonable cost. If you want maximum adjustability for track use, the KW Variant 3 coilover kit is the premium choice.
