  1. FAPO PF Coilovers for Audi Q5, A4, A5, A6, A7, S4, S5, RS5 (2017-2024)

    FAPO PF Coilovers for Audi Q5, A4, A5, A6, A7, S4, S5, RS5 (2017-2024)

    Best Overall for Performance Customization

    View Latest Price

    This FAPO PF Coilover kit stands out for its comprehensive adjustability, especially with 32-level damping and height modifications, making it a versatile choice for enthusiasts who want precise control over handling and stance. Compared to the Rev9 Hyper-Street II, which offers similar damping flexibility, the FAPO’s mono-tube design enhances heat dissipation during aggressive driving, a key advantage for track use. However, its need for professional installation and the fact that it doesn’t accommodate factory ride height may deter casual users seeking a straightforward upgrade. This kit is ideal for those seeking a highly customizable suspension experience and are willing to invest in setup and installation.

    Pros:
    • Highly adjustable damping with 32 levels for fine-tuning handling
    • Full height adjustment to achieve desired stance
    • Mono-tube design improves heat dissipation and response
    • Suitable for aggressive driving and track use
    Cons:
    • Requires professional installation; not beginner-friendly
    • Does not support factory ride height; lowering only
    • Ride comfort may be compromised at maximum lowering

    Best for: Performance-oriented drivers who want maximum customization and are comfortable with installation complexity

    Not ideal for: Casual drivers or those seeking a plug-and-play upgrade without modifying ride height or suspension geometry

    • Compatibility:Audi Q5 2nd Gen FY 2018-2024, A4 5th Gen B9/8W 17-24, S4 B9 18-24
    • Adjustable damping:32 levels
    • Height adjustment:Yes, lowers by 1-3 inches
    • Spring rate:Front: 8 kg/mm, Rear: 10 kg/mm
    • Spring preload:7-10mm
    • Tube diameter:2.09 inches
    • Piston size:1.77 inches
    • Warranty:1 year
    Our verdict
    “This kit is perfect for enthusiasts demanding precise handling and customization, willing to handle installation complexity.”
  2. Rev9 Hyper-Street II Coilover Kit for Audi A4 / S4 (B9) 2018-2020, 32-Way Damping Adjustment

    Rev9 Hyper-Street II Coilover Kit for Audi A4 / S4 (B9) 2018-2020, 32-Way Damping Adjustment

    Best Value with Precise Damping Control

    View Latest Price

    The Rev9 Hyper-Street II offers a compelling balance of features for the price, with 32-way damping adjustment and full-length height control, making it a solid choice for those who want a lowered stance without sacrificing handling precision. Unlike the more advanced FAPO kit, which emphasizes heat dissipation and durability, Rev9 prioritizes affordability while still providing customizable ride quality for street and spirited driving. The lack of included installation instructions and the focus on lowering-only setups means it’s better suited for experienced DIYers or professionals. This kit suits drivers who want a flexible suspension upgrade at a more accessible price point.

    Pros:
    • 32-way damping adjustment for tailored handling
    • Full length height adjustment for lowered stance
    • Affordable compared to premium options
    • Good for street and spirited driving
    Cons:
    • No installation instructions included; requires professional setup
    • Designed primarily for lowered vehicles; does not support factory height
    • Limited to street use; track performance may be compromised

    Best for: Budget-conscious enthusiasts who want adjustable handling and a lowered stance without extensive setup complexity

    Not ideal for: Beginners or those needing a factory ride height compatible setup or daily comfort focus

    • Compatibility:Audi A4 / S4 (B9) 2017-2020
    • Excludes:Electronic suspensions
    • Front Spring Rate:10 kg/mm
    • Rear Spring Rate:5 kg/mm
    • Damping Adjustment:32-way
    • Shock Type:Mono-tube
    • Full Length Adjustment:Yes
    • Independent Spring Tension:Yes
    Our verdict
    “This coilover kit offers excellent damping adjustability at a budget, ideal for DIYers seeking a lowered but customizable ride.”
  3. Rev9 Hyper-Street II Coilover Kit for Audi A4 (B8) Sedan 2009-2016, 32-Way Damping Adjustment

    Rev9 Hyper-Street II Coilover Kit for Audi A4 (B8) Sedan 2009-2016, 32-Way Damping Adjustment

    Best for Classic B8 Owners Needing Custom Tuning

    View Latest Price

    This Rev9 B8 coilover kit continues to deliver on damping flexibility with 32 levels, making it a good choice for owners of older A4 models who want to tailor their ride. While it shares many features with the B9 version, the B8 setup is best for those who prefer a more traditional, non-electronic suspension. Its independent spring tension and ride height adjustment allow for a range of tuning options, but it does not restore factory ride height, which could be a downside for those seeking a more comfortable daily driver. Compared with the B9 model, it’s a more affordable option that still offers solid handling tuning but lacks some modern refinements.

    Pros:
    • 32-level damping adjustment for detailed tuning
    • Independent spring tension and height adjustments
    • Durable steel alloy shocks
    • Affordable for older model upgrades
    Cons:
    • No included installation instructions; professional setup recommended
    • Cannot restore factory ride height; lowering only
    • May require technical expertise for optimal setup

    Best for: Owners of B8 A4/S4 models seeking customizable suspension with a budget focus

    Not ideal for: Those looking for a factory ride height or primarily street comfort on a daily driver

    • Spring Rate Front:8 kg/mm
    • Spring Rate Rear:5 kg/mm
    • Damping Adjustment:32-way
    • Compatibility:Audi A4 / S4 B8 2009-2016
    • Installation:Professional recommended
    • Note:Lowering kit does not adjust to factory ride height
    Our verdict
    “This coilover kit suits B8 owners aiming for custom handling adjustments without the need for factory ride height restoration.”
  4. Godspeed MonoSS Coilover Suspension Kit for Audi A4 / Quattro (B8) 2009-2016

    Godspeed MonoSS Coilover Suspension Kit for Audi A4 / Quattro (B8) 2009-2016

    Best Street/Track Hybrid Performance

    View Latest Price

    The Godspeed MonoSS coilovers are built with quality in mind, featuring Japanese KOYO bearings and a monotube design for durability and smooth response, particularly suited for street and track use on B8 models. The 16 rebound force levels provide a decent range of damping options, but fall short of the 32-way adjustability found in other kits like Rev9 or FAPO, meaning finer tuning is limited. Compared with FAPO’s more adjustable and higher-spec kits, Godspeed focuses on providing a reliable, high-performance setup for those who want a good balance of street comfort and track readiness without the complexity of extensive adjustments.

    Pros:
    • Japanese KOYO bearings for smooth operation
    • Durable steel construction with high-performance springs
    • Monotube design improves response and heat dissipation
    • Suitable for street and track day use
    Cons:
    • Limited damping adjustment with only 16 levels
    • Not designed for extensive tuning or lowering beyond a certain point
    • Installation should be handled by professionals for best results

    Best for: Drivers who want a reliable, high-quality coilover for street and occasional track use without complex tuning needs

    Not ideal for: Tuning enthusiasts seeking maximum damping adjustment or factory ride height compatibility

    • Spring Rate (Front/Rear):10 kg/mm / 6 kg/mm
    • Damping Levels:16 rebound force levels
    • Shock Tube Diameter:52mm
    • Shock Material:Seamless steel
    • Adjustability:16 levels of damping
    • Warranty:1 year
    Our verdict
    “This coilover kit offers durable, reliable performance with sufficient adjustability for daily and spirited driving, ideal for those prioritizing quality over maximum tuning options.”
  5. Rev9 Hyper-Street II Coilover Kit for Audi S4 (8K) 2010-2016, 32-Way Damping Adjustment

    Rev9 Hyper-Street II Coilover Kit for Audi S4 (8K) 2010-2016, 32-Way Damping Adjustment

    Best for Customization and Fine-Tuning

    View Latest Price

    This kit stands out for its 32-level damping adjustment, allowing precise control over ride comfort and handling, which makes it more suitable for enthusiasts who want tailored performance. Compared with the AdlerSpeed 18-Way Damper Coilovers, it offers even finer tuning options, though it lacks installation instructions, increasing complexity for new installers. The mono-tube design with steel alloy bodies ensures durability, but it does not restore factory ride height, so it’s better suited for those seeking adjustable performance rather than a simple drop. Its independent height and stiffness adjustments improve handling without sacrificing ride quality, making it a strong choice for custom setups.

    Pros:
    • 32-level damping adjustment for precise tuning
    • Independent ride height and stiffness controls
    • Durable mono-tube steel alloy construction
    Cons:
    • No installation instructions included, requiring professional help
    • Does not restore factory ride height, limiting basic drop options

    Best for: Advanced enthusiasts who want detailed damping control and custom ride tuning for their Audi S4 (8K).

    Not ideal for: DIY beginners who prefer a straightforward installation or a kit with included instructions.

    • Compatible Vehicles:Audi S4 (8K) 2010-2016
    • Spring Rate (Front/Rear):8 kg/mm / 5 kg/mm
    • Damping Adjustment:32 levels
    • Type:Mono tube shock
    • Body Material:Steel alloy
    • Lowering Kit:Yes
    Our verdict
    “Ideal for experienced tuners seeking maximum damping adjustability for their Audi S4.”
  6. Rev9 Hyper-Street II Coilovers for Audi A4 (B8) Sedan 2009-2016

    Rev9 Hyper-Street II Coilovers for Audi A4 (B8) Sedan 2009-2016

    Best for Versatile Performance and Handling

    View Latest Price

    This set offers 32 damping levels and ride height adjustability, making it a versatile option for owners who want a sporty stance and customizable handling. Unlike the maXpeedingrods Coilover Kit, which emphasizes affordability, this kit leans toward more refined tuning with professional-grade mono-tube shocks and independent spring and height adjustments. While it doesn’t include installation instructions, its durable construction with high-quality materials makes it suitable for experienced DIYers or professional installers aiming for a tailored driving experience. It strikes a balance between performance and durability, especially for those who want to fine-tune their suspension without sacrificing ride quality.

    Pros:
    • 32 damping levels for precise ride control
    • Independent spring tension and ride height adjustments
    • High-quality mono-tube shock design
    Cons:
    • Installation recommended for experienced technicians
    • No included installation instructions can complicate setup

    Best for: Performance-minded owners who desire a high level of damping and ride height customization for daily driving or spirited outings.

    Not ideal for: Beginners or casual drivers who prefer a simple, plug-and-play upgrade without complex setup or tuning.

    • Fitment:2009-2016 Audi A4 (B8) Sedan / Quattro
    • Spring Rate (Front/Rear):8 kg/mm / 5 kg/mm

    Our verdict
    “Best suited for enthusiasts who want high-performance tuning for their Audi A4 (B8).”
  7. AdlerSpeed 18-Way Damper Coilovers Suspension Kit for Audi A4, A5, S4 (2008-2016)

    AdlerSpeed 18-Way Damper Coilovers Suspension Kit for Audi A4, A5, S4 (2008-2016)

    Best for Durability and Professional Tuning

    View Latest Price

    This kit is distinguished by its 18-way damping adjustment and highly durable materials, including electroless nickel-plated shock bodies and aircraft-grade aluminum springs, making it ideal for those who demand longevity and performance. Compared with the Rev9 Hyper-Street II options, it offers fewer damping levels but emphasizes robustness and corrosion resistance, suitable for high-mileage or demanding environments. Its professional-grade construction suggests it’s best for those with installation experience or access to tuning shops, as it doesn’t include instructions or simple DIY features. For owners who prioritize long-term durability and fine-tuning, this kit offers a solid foundation.

    Pros:
    • High durability with corrosion-resistant components
    • 18 damping adjustment levels for tuning flexibility
    • Excellent build quality for long-term use
    Cons:
    • Requires professional installation for best results
    • Limited to specific Audi models, reducing versatility

    Best for: Owners seeking a highly durable suspension upgrade with professional tuning potential for daily driving or track use.

    Not ideal for: DIY novices or those looking for straightforward installation with detailed instructions.

    • Application:Audi A4, A5, S4 (2008-2016)

    maXpeedingrods Coilover Suspension Kit for Audi A4/S4 B6/B7 2002-2008, 24 Levels Damper Adjustable, Height Adjustable, Blue

    Best for Budget-Conscious Performance

    View Latest Price

    This coilover kit offers 24 damping adjustment levels and a generous height adjustment range, making it a compelling choice for owners who want a balance of performance and affordability. Compared with the Solo Werks S1 setup, it provides more damping levels, giving more tuning options without a high-end price tag. Its high-quality springs and corrosion-resistant components add durability, but installation can be tricky for beginners due to the multiple adjustment steps. It’s well-suited for street use, mountain driving, or even light track days, providing flexible performance at a more accessible price point.

    Pros:
    • 24 damping levels for versatile tuning
    • Height adjustable for aggressive stance
    • High-quality stress-tested springs
    Cons:
    • Installation may be complex for beginners
    • Adjustments require technical skill to optimize

    Best for: Budget-conscious drivers who want adjustable suspension for street and occasional spirited driving.

    Not ideal for: Less experienced do-it-yourselfers or owners seeking a simple, no-fuss upgrade with minimal setup.

    • Fit:Audi A4/S4 B6/B7 2002-2008

    Solo Werks S1 Coilover Kit for Audi 2008-2015 A4, S4, A5, S5, RS5, Allroad (Model S1AU006)

    Best for Durability and Ease of Adjustment

    View Latest Price

    This kit’s heavy-duty zinc-plated housings and 3-year warranty emphasize longevity, making it a reliable choice for daily drivers. Its simple height adjustment from 1.0 to 3.0 inches, combined with twin-tube shock design, offers straightforward handling improvements. While it lacks the fine damping control found in the Rev9 Hyper-Street II or AdlerSpeed kits, it compensates with easy installation and maintenance. Its corrosion-resistant features suit owners looking for a durable upgrade that doesn’t require complex tuning or professional setup, especially for those who prioritize longevity over extensive damping adjustments.

    Pros:
    • Durable corrosion-resistant construction
    • Easy height adjustment with D-shaped threads
    • 3-year warranty adds peace of mind
    Cons:
    • Fixed dampening limits customization
    • Compatibility limited to specific models

  10. Raceland Classic Coilovers for Audi S4 B8 Quattro (2008-2015)

    Raceland Classic Coilovers for Audi S4 B8 Quattro (2008-2015)

    Best Budget-Friendly Performance Upgrade

    View Latest Price

    The Raceland Classic Coilovers stand out for offering a solid balance between affordability and performance. Compared to more complex damping systems like the Rev9 Hyper-Street II kits, these coilovers focus on straightforward height adjustment, making them appealing for enthusiasts seeking a lowered stance without high costs. While they provide noticeable improvements in handling, stability, and grip, especially for daily driving, their lower end of damping customization means they lack the fine-tuning of premium options. The powder-coated components resist corrosion well, and the lifetime warranty adds peace of mind. However, the lower ride height might require wheel spacers or fender rolling for certain wheel setups, and installation could challenge those new to suspension work. This kit makes the most sense for budget-conscious drivers wanting a reliable upgrade that enhances handling without sacrificing daily comfort.

    Pros:
    • Affordable price point with solid performance gains
    • Adjustable height from 1 to 3 inches lower than stock
    • Corrosion-resistant powder-coated components
    • Backed by lifetime warranty and satisfaction guarantee
    Cons:
    • Lowering may require additional wheel fitment adjustments like spacers
    • Installation can be complex for those unfamiliar with suspension work

    Best for: Budget-conscious enthusiasts seeking a reliable, adjustable coilover that improves handling and stance.

    Not ideal for: Beginners or perfectionists who want extensive damping customization or complex suspension tuning.

    • Fit:2008-2015 Audi S4 Quattro
    • Spring Rates:515 lbs/in (F), Progressive (R)
    • Height Adjustment:1-3 inches lower than factory
    • Corrosion Resistance:Powder-coated components
    • Warranty:Lifetime
    • Installation:Complex for beginners
    Our verdict
    “This coilover kit is well-suited for drivers who want a cost-effective way to lower their S4 and improve handling without extensive tuning.”

Factors to Consider When Choosing Best Coilover Kits For Audi S4

Selecting the right coilover kit for your Audi S4 involves considering several key factors. Beyond price, understanding adjustability, ride comfort, and durability will help you make a smart choice. Proper fitment for your specific model year is also critical, as compatibility issues can compromise performance. Keep in mind that more adjustable kits often come with increased complexity, which might require more maintenance or technical knowledge. By weighing these factors carefully, you can find a kit that enhances your driving experience without unexpected surprises.

Adjustability and Tuning Options

Look for kits that offer adjustable damping and height settings if you want to fine-tune your ride. More adjustment options, like 32-way damping, give you precise control over handling and comfort, but they can also add complexity. For daily drivers, simpler setups with limited adjustability may suffice and reduce maintenance worries. Consider your driving style and willingness to tweak settings when choosing a kit to avoid overcomplicating your setup.

Build Quality and Material Durability

High-quality materials such as anodized aluminum or stainless steel tend to last longer and resist corrosion. Cheaper kits may use inferior components that wear out faster or fail under stress. Durability is especially important if you plan to drive aggressively or in harsh conditions. Investing in a well-built kit can save money in the long run by avoiding frequent replacements or repairs.

Ease of Installation and Maintenance

Some coilover kits are designed for straightforward installation with detailed instructions, while others may require professional help. If you’re a DIY enthusiast, look for kits with comprehensive guides and user-friendly features. Also, consider how accessible the components are for future adjustments or repairs—kits that are easier to maintain can save you time and frustration over the years.

Price and Overall Value

While higher-priced kits often provide better adjustability and durability, they may be unnecessary for casual drivers. Conversely, very inexpensive options might save money upfront but could lead to compromises in ride quality or longevity. Determining your budget and understanding what features are essential for your use case will help you find a kit that offers the best value for your investment.

Compatibility and Fitment

Ensuring the coilover kit is compatible with your specific Audi S4 model year and trim is critical. Mismatched kits can lead to handling issues or installation problems. Always verify the product details and consult with the manufacturer or seller if unsure. Correct fitment ensures optimal performance and safety.

Frequently Asked Questions

Can I install coilovers myself on my Audi S4?

Installing coilovers on an Audi S4 can be a manageable project for someone with basic mechanical skills and the right tools. Many kits include detailed instructions, and online tutorials can guide you through the process. However, if you lack experience or want to ensure proper alignment and safety, professional installation is recommended. Proper setup is essential to avoid handling issues and uneven tire wear over time.

Will coilovers ruin my ride comfort on a daily driver?

Not necessarily. Quality coilovers with adjustable damping can be tuned to provide a comfortable ride while enhancing handling. Cheaper or overly stiff kits might sacrifice comfort for performance, leading to a harsher ride. The key is selecting a kit that balances ride quality with your driving style, and fine-tuning the damping settings can help achieve that balance.

How long do coilovers typically last?

The lifespan of coilovers depends on build quality, driving conditions, and maintenance. Well-made kits from reputable brands can last 50,000 miles or more if properly maintained. Regular inspections, cleaning, and adjustments can extend their life, but neglecting these factors might lead to premature wear or failure. Choosing a durable, high-quality kit is an investment in longevity.

Are adjustable coilovers worth the extra cost?

Adjustable coilovers offer significant benefits if you want to customize your ride for different driving conditions or preferences. They allow you to fine-tune ride height and damping for better handling or comfort. However, if you prefer a set-it-and-forget-it approach, a non-adjustable kit may suffice at a lower cost. The decision depends on your willingness to tweak settings and your performance expectations.

What should I prioritize if I’m on a tight budget?

For budget-conscious buyers, basic coilover kits like Raceland can deliver acceptable performance and improved stance. Be aware that these options might lack advanced damping adjustments or long-term durability, so they are best suited for casual use. Investing in a slightly higher-quality, mid-range kit could provide better reliability and a more comfortable ride without significantly increasing costs.

Conclusion

For most Audi S4 owners, the Rev9 Hyper-Street II offers a compelling mix of adjustability, durability, and value, making it the best overall choice. If budget is a primary concern, the Raceland Classic provides a straightforward upgrade, though with fewer features. Enthusiasts seeking a premium experience should consider the FAPO PF Coilovers for their combination of build quality and tuning options. Beginners or those new to coilovers will appreciate kits with easy installation and straightforward adjustments, like the Solo Werks S1. Ultimately, your choice should reflect your driving style, budget, and desire for customization, ensuring you get the best fit for your needs.
