The Infiniti Q60 Suspension Upgrade Guide: Transform Your Coupe’s Handling
You’re carving through a winding canyon road, and your Q60 feels like it’s floating instead of gripping—the body rolls, the steering feels vague, and you know this chassis deserves better. Here’s everything you need to know about upgrading your Infiniti Q60 suspension to match its sports car looks with genuine performance.
TL;DR
Upgrading your Infiniti Q60’s suspension can dramatically improve handling, reduce body roll, and give you a more connected driving experience. The main options range from budget-friendly lowering springs (around $400) to full coilover systems (starting at $660) and advanced air suspension (over $1,000). Quality sway bars can reduce body roll by over 200% compared to stock. However, AWD models require careful component selection due to different spring rates and fitment issues, with some owners reporting problems on specific setups.
Key Takeaways
- Lowering springs like ARK GT-S ($443) and Eibach Pro-Kit ($395) offer a 1.3-1.4 inch drop while working with OEM shocks
- Coilovers provide adjustable ride height and damping—the Air Lift Performance system offers 32-way damping adjustment and up to a 5-inch drop
- Sway bars dramatically reduce body roll—aFe CONTROL bars are 160-225% stiffer than stock
- AWD models have unique needs—the factory spring rates are softer (6-7k front, 3-4k rear) and some owners recommend stiffer springs (12k front, 8k rear) to prevent bottoming out
- Air suspension from Air Lift gives you on-the-fly height adjustment with 30 levels of damping via Bluetooth control
- Be careful with bargain coilovers—one Q60 owner reported poor experiences with Silvers NeoMax, calling the dampers “the biggest piece of garbage I’ve ever installed”
Understanding Your Q60’s Suspension
What’s Under the Car
The Infiniti Q60 comes with a sophisticated independent suspension—double wishbone up front and a multi-link setup in the rear. Higher trims like the Red Sport 400 include Infiniti’s Dynamic Digital Suspension (DDS) system that adapts damping in real-time.
Here’s the thing about that stock setup—it’s tuned for comfort, not cornering. The suspension prioritizes a smooth ride over flat handling, which means body roll during aggressive driving and less feedback through the steering wheel.
RWD vs. AWD Considerations
This is really important if you own an AWD Q60. The factory spring rates are softer on AWD models (6-7k front, 3-4k rear), and aftermarket kits often need adjustment. One Q60 owner who installed Silvers NeoMax coilovers on their AWD Red Sport found the car “bottoms out a lot” and “jumps on every bump,” eventually concluding the dampers were defective.
“AWD owners should consider stiffer spring rates—many recommend 12k in the front and 8k in the rear to prevent the car from sitting too low and restore usable travel.” — Q60 owner forum advice
Suspension Upgrade Options
Lowering Springs
Best for: Budget-conscious owners who want a sportier look and mild handling improvement.
Lowering springs are the most affordable way to improve your Q60’s stance and handling. They work with your factory shocks and struts, so installation is relatively straightforward.
ARK GT-S Lowering Springs ($443.20)
- Front drop: 1.3 inches
- Rear drop: 1.4 inches
- Front spring rate: 7.0 kg/mm
- Rear spring rate: 2.0-3.0 kg/mm
- Fitment: Q60 Coupe 3.0T RWD (2017+)
Eibach Pro-Kit ($395.00)
- Progressive spring design for excellent ride quality
- Lower center of gravity for better control
- Fitment: Q60 Base and Red Sport RWD (2017-2022)
Godspeed Project Traction-S Springs
- Front drop: 1.1 inches, Rear drop: 0.8 inches
- Spring rate: 7.2 kg/mm (front), 2.6 kg/mm (rear)
- Designed to work with OEM shocks
Coilovers
Best for: Enthusiasts who want adjustable ride height and damping for track days or dialed-in street performance.
Coilovers replace your entire shock and spring assembly, giving you complete control over ride height and damping characteristics.
Air Lift Performance Coilovers ($1,149.99)
- 32-way damping adjustment
- 12kg front spring rate, 5kg rear spring rate
- Up to 4-inch front drop, 5-inch rear drop
- Convertible to full air suspension
- Fitment: Q60 RWD (2016-2022)
Tein Street Advance Z Coilovers ($660.33)
- 16-stage damping adjustment
- 9kg front, 8kg rear spring rates
- EDFC compatible (in-cab damping control)
- Uses OEM top mounts
- Made in Japan
Ksport Kontrol Pro Coilovers
- 36-way adjustable damping
- 12kg front, 6.3kg rear spring rates
- Monotube high-pressure design
- Fitment: Q60 Coupe RWD
Sway Bars (Anti-Roll Bars)
Best for: Reducing body roll during cornering without changing ride comfort.
Sway bars are one of the most effective handling upgrades you can make. They connect the left and right suspension, reducing body roll during cornering while maintaining straight-line ride quality.
aFe CONTROL Sway Bar Set ($556.00)
- Front: 35mm diameter, 2-way adjustment
- Rear: 1.125-inch diameter, 3-way adjustment
- Stiffness increase: 160-225% stiffer than stock
- Front adjustment: 1000-1125 lbs/in
- Rear adjustment: 730-1040 lbs/in
- Includes polyurethane bushings and billet aluminum brackets
The front bar has 2-way adjustment (1000 or 1125 lbs/in stiffness), and the rear has 3-way adjustment (730, 875, or 1040 lbs/in). This gives you fine control over the handling balance—stiffer rear bars promote more oversteer, while stiffer front bars promote understeer.
Air Suspension
Best for: Show cars and owners who want extreme adjustability from show stance to track-ready.
Air suspension replaces coil springs with air bags, letting you adjust ride height on the fly from inside the car.
Air Lift Performance Complete Kit
- Full air management system with wireless controller
- Viair 444c compressor and tank included
- 30 levels of damping adjustment
- Bluetooth control via iOS/Android app
- 3H system adds height sensors for consistent ride height regardless of load
- Up to 3 inches of threaded adjustability
The 3P system is pressure-based, while the 3H system adds height sensors that give real-time feedback, ensuring consistent ride height even with passengers or cargo.

What Q60 Owners Say
Real-World Experience with Silvers NeoMax Coilovers
One Q60 Red Sport AWD owner documented their disappointing experience with Silvers NeoMax coilovers on the Infiniti Q60 forums:
“The car actually drives much worse than before… It jumps on every bump and feels unstable in corners, especially on uneven roads. The Neomax dampers are the biggest piece of garbage I’ve ever installed on any car.”
The owner reported:
- Car bottomed out frequently in the front
- Rear right side made constant knocking from the top mount
- Support from the manufacturer was terrible
- Springs dropped 2 inches over 8 months
Their solution: Installing RS-R Best i Active coilovers, which they described as “extremely satisfied” and “a completely different vehicle now.” This highlights the importance of choosing quality components, especially for AWD models.
FAQ: Q60 Suspension Upgrades
What’s the cheapest way to improve Q60 handling?
Lowering springs like the Eibach Pro-Kit or ARK GT-S are the most affordable option at around $400. Combined with a rear sway bar, this is a solid entry-level upgrade.
Do I need a tune after installing coilovers?
No—suspension upgrades don’t require engine tuning. However, a professional alignment is essential after any suspension work. Lowering your car changes the suspension geometry, and a proper alignment ensures even tire wear and predictable handling.
Can I install coilovers myself?
If you’re mechanically inclined with basic tools and a jack, yes. However, coilover installation is time-consuming, and proper setup requires careful adjustment of ride height, preload, and damping. Many owners recommend professional installation for air suspension systems.
Will lowering springs work with my factory shocks?
Yes—most lowering springs like the ARK GT-S and Eibach Pro-Kit are designed to work with OEM shocks and struts. However, aftermarket shocks will perform better at lower ride heights.
Which suspension upgrade is best for daily driving?
Coilovers like the Tein Street Advance Z offer 16-stage damping adjustment, letting you dial in a comfortable daily ride and firm it up for weekend drives. The progressive springs from Eibach also maintain excellent ride quality.
Do I need special parts for AWD Q60?
Yes. AWD models have different spring rates and fitment requirements. Many owners recommend stiffer front springs (12k vs. the default 10k) to prevent bottoming out. Always verify fitment with the manufacturer before purchasing.
