Why Upgrade the Nissan GT-R Suspension?

The Nissan GT-R, particularly the R35 generation, is celebrated for its all-wheel-drive system, twin-turbo V6, and capable chassis. Yet even from the factory, the suspension is a compromise between daily livability and track performance. Enthusiasts who push the car beyond street driving—whether at autocross, road courses, or time attack events—quickly discover that the stock suspension leaves handling potential on the table. Upgrading to aftermarket coilovers and adjustable arms transforms the GT-R into a more precise, predictable, and confidence-inspiring machine. This guide explores how these upgrades work, what to look for, and how to get the most out of your GT-R’s suspension.

Understanding Coilovers for the GT-R

Coilovers integrate the shock absorber and coil spring into a single threaded assembly, replacing the factory separate spring-and-damper setup. This design allows for ride-height adjustability, damping tuning, and often spring preload adjustment. For the GT-R, coilovers offer several key advantages over factory components.

How Coilovers Differ From Stock Shocks and Springs

Factory GT-R dampers are valved for comfort and general mass-market appeal. They use fixed spring rates and non-adjustable ride height. Aftermarket coilovers typically feature adjustable damping (often both compression and rebound), much stiffer spring rates, and a threaded lower mount that lets you lower the car anywhere from 0.5 to 3 inches. This adjustability is critical for optimizing weight transfer and cornering grip.

Types of Coilovers Available

  • Street-oriented coilovers – Offer a moderate spring rate (8–12 kg/mm front, 10–14 kg/mm rear) and a focus on ride compliance. Brands like BC Racing and Tein produce well-regarded street sets.
  • Track-focused coilovers – Use higher spring rates (14–18 kg/mm front, 16–20 kg/mm rear) and more aggressive damping. Öhlins and KW Automotive offer top-tier track kits with independent adjustments.
  • Competition-level coilovers – Often feature remote reservoirs, separate compression and rebound knobs, and custom spring rates. These are for serious time attack or racing builds.

Benefits of Upgrading to Coilovers

Switching to coilovers delivers measurable improvements in handling, stability, and driver feedback. The gains go beyond just lowering the car.

  • Reduced body roll and improved turn-in – Stiffer springs and well-tuned dampers keep the GT-R flat through corners, allowing earlier throttle application.
  • Better weight transfer management – Adjustable damping lets you dial in how quickly weight shifts to the front under braking and to the rear on acceleration. This improves traction out of corners.
  • Lower center of gravity – Dropping the ride height reduces the transfer of lateral weight, increasing maximum cornering speed.
  • Customizable ride height for stance or performance – Lowering the car not only improves aesthetics but also lowers the roll center, which can be corrected with adjustable arms (discussed later).
  • More direct steering feel – Reduced bushing compliance and stiffer damping transmit road surface information more clearly through the steering wheel.

A well-chosen set of coilovers transforms the GT-R from a heavy grand tourer into a sharp-edged handling tool. Even on the street, the improvement in responsiveness is immediately noticeable.

Choosing the Right Coilovers for Your GT-R

Selecting coilovers for the Nissan GT-R requires careful consideration of your driving goals, budget, and willingness to adjust settings. The GT-R’s heavy curb weight (~1,740 kg or 3,835 lbs) demands robust components that can handle repeated hard use.

Key Selection Criteria

  • Driving use – Pure street cars can use softer springs (8–10 kg/mm) with focus on compliant damping. Dual-purpose cars benefit from 10–14 kg/mm springs. Dedicated track cars often run 14–18 kg/mm or higher.
  • Adjustability range – Look for independent rebound and compression adjustment. Some high-end units also offer separate high- and low-speed compression adjustments.
  • Build quality and materials – Stainless steel or anodized bodies resist corrosion; monotube designs dissipate heat better than twin-tube. Check for stainless steel spring perch adjusters and durable hardware.
  • Reservoir design – Remote reservoirs increase oil volume and improve heat dissipation, vital for track sessions. Inline reservoirs (pigtail) are more compact and easier to install.
  • Spring seat design – Helper springs or tender springs keep the main spring seated at full droop, preventing noise and damage.
  • KW Variant 3 – Very popular for the GT-R, with independent rebound and compression, stainless steel bodies, and a 2-year warranty. Good for street and track.
  • Öhlins Road & Track DFV – Dual-flow valve technology provides excellent low-speed compliance and firm high-speed damping. A top choice for aggressive street driving.
  • BC Racing BR Series – More budget-friendly option with 30 clicks of damping adjustment and pillowball upper mounts. Wide range of spring rates available.
  • JRZ RS Pro – High-end monotube dampers with remote reservoirs, used in many competitive racing GT-Rs.

Regardless of brand, ensure the coilovers are specifically designed for the R35 GT-R chassis (or R32/R33/R34 if applicable). Custom spring rates may need to be ordered separately if you are outside the typical street range.

Adjustable Arms: Restoring and Improving Suspension Geometry

When you lower a GT-R on coilovers, the suspension geometry changes significantly. The factory control arms have fixed lengths, so lowering changes camber, caster, and toe angles. Without correction, you may experience excessive negative camber, poor tire contact patch, and accelerated wear. Adjustable arms address these issues by providing threaded or slotted adjustments for alignment settings.

Types of Adjustable Arms for the GT-R

  • Front upper control arms – Allow adjustment of camber and caster. Essential for correcting camber loss when lowering (the front tends to gain negative camber).
  • Rear camber arms – Replace the factory upper link, letting you adjust camber from about –0.5° to –3.0° or more. Critical for setting consistent tire wear across the rear axle.
  • Rear toe arms – Control toe angle. Even small toe changes affect stability, especially on corner exit. Adjustable toe arms prevent toe-in or toe-out issues after lowering.
  • Traction arms (rear lower links) – Adjust wheelbase length and pinion angle. They can help reduce wheel hop and improve rear traction under hard acceleration.
  • Front tension rods – Allow caster adjustment, which affects steering feel and straight-line stability.

Why Adjustable Arms Are a Must With Coilovers

Even a modest 1-inch drop on the GT-R can shift rear camber from the factory –1.0° to –2.5° or more. That much negative camber increases cornering grip but prematurely wears the inside edges of the tires. Adjustable arms let you dial the camber back to a street-friendly –1.5° to –2.0° while keeping aggressive track settings easily accessible. Additionally, adjustable arms help keep the suspension within the manufacturer’s ride-height range, preventing the roll center from dropping too low, which can create poor transitional behavior.

Benefits of Upgrading to Adjustable Arms

  • Precise alignment control – Set camber, caster, and toe exactly where you want them, not where the factory geometry forces you.
  • Extended tire life – Even tire wear means you get the maximum life from expensive tires, a significant cost saving on a car that eats tires.
  • Better cornering stability – With proper camber, the tire maintains a larger contact patch during cornering, increasing grip and reducing understeer or oversteer.
  • Improved bump steer characteristics – Adjusting the length of the tie rod ends with adjustable tie rods can reduce unwanted steering input over bumps.
  • Future-proofing for additional suspension upgrades – Once you install adjustable arms, you can easily change ride height or alignment settings without needing to buy new parts.

Many GT-R owners pair coilovers with at least front upper control arms and rear camber and toe arms to unlock the full potential of the handling package.

Installation Considerations for Coilovers and Adjustable Arms

Installing these components requires mechanical confidence and proper tools. The GT-R’s suspension is robust but can be challenging on jack stands due to heavy subframes and tight spaces. Here is a realistic overview.

Tools and Preparation

Beyond standard sockets, you will likely need:

  • Torque wrench accurate to ~150 N·m (110 ft-lb)
  • Spring compressors (if reusing factory springs, though not typically needed for coilovers)
  • Ball joint separator (pickle fork or tie rod puller)
  • Rubber mallet for stubborn bolt removal
  • Alignment tools or a nearby shop with a hunter rack for final settings

Step-by-Step Installation Outline

  1. Preparation – Secure the car on jack stands, remove wheels, and loosen all suspension bolts while the car is on the ground to avoid rotating bushings.
  2. Remove factory shocks and springs – Unbolt the lower link, strut mount, and any wiring (for factory active damping). Mark or disconnect the ride height sensors.
  3. Install coilovers – Assemble the coilovers (pre-load spring, fit camber plates if included). Attach the lower mount to the hub assembly and the upper mount to the chassis. Hand-tighten all bolts.
  4. Adjust ride height – Set the spring perch to achieve the desired ride height. Lower the car onto its wheels and bounce the suspension to settle it. Measure and adjust as needed.
  5. Install adjustable arms – For each arm, remove the factory link (e.g., upper control arm, toe arm). Install the adjustable replacement, loosely threading the bolts. Ensure the adjustment mechanism (spherical bearing or slotted style) is in a safe range.
  6. Final torque – With the car on the ground at ride height, torque all suspension bolts to factory specifications. For spherical bearings, use medium-strength thread locker.
  7. Alignment – Take the car to a shop that understands GT-R alignment. Provide your desired camber, caster, and toe values. After alignment, verify that all adjustable arms are within their adjustment range.

Professional Installation vs. DIY

While many enthusiasts install coilovers and arms themselves, the GT-R’s complexity—especially with active suspension wiring and the requirement for a precise alignment—often makes professional installation worthwhile. A certified shop can complete the job in 4–8 hours, including alignment. Expect labor costs between $800 and $1,500 depending on region and shop rates. DIY saves money but requires careful attention to torque specs and alignment preparation.

Tuning and Alignment After Upgrades

Once coilovers and adjustable arms are installed, proper tuning is essential. The stock alignment specifications assume a factory ride height; you will need to develop custom targets.

ParameterStreet (mild lowering)Street/track (1–1.5" drop)Track only (aggressive drop)
Front camber–1.0° to –1.5°–2.0° to –2.5°–3.0° to –3.5°
Rear camber–1.0° to –1.5°–1.5° to –2.0°–2.0° to –2.5°
Front caster+7.0° to +7.5°+6.5° to +7.0°+6.0° to +6.5°
Front toe0 to +0.10° (slight toe-in)–0.10° to 0° (near zero)–0.15° to –0.20° (slight toe-out)
Rear toe+0.10° to +0.20° (toe-in)+0.10° to +0.15°+0.05° to +0.10°

These are starting points. Fine-tune based on tire wear patterns, steering response, and lap times. Many GT-R owners also adjust sway bar end links or upgrade to adjustable sway bars to balance front and rear roll stiffness.

Damping Settings

Start with the manufacturer’s recommended base settings (often 10–15 clicks from full stiff). Drive on a familiar road, then adjust in increments of 2–3 clicks. For street use, aim for a firm but controlled ride; on track, increase compression and rebound to reduce body movement. Keep notes of your settings so you can revert easily.

Common Mistakes to Avoid

  • Ignoring bump steer – After lowering, bump steer can become pronounced. Consider adjustable tie rods or bump-steer correction kits.
  • Over-tightening spherical bearings – Spherical ends should not be torqued to the same spec as rubber bushings. Follow the arm manufacturer’s instructions.
  • Skipping corner balancing – For serious track use, corner-weight the car after installation. This ensures even weight distribution across all four corners.
  • Forgetting to reset the ride-height sensors – The GT-R’s active damping and headlight leveling systems rely on ride-height sensors. If you lower the car, the sensor arm may need to be reclocked or the linkage adjusted to prevent error codes.

Conclusion

Upgrading the Nissan GT-R’s suspension with high-quality coilovers and adjustable arms is one of the most rewarding modifications you can make. The combination of adjustable damping and ride height with corrected suspension geometry unlocks the chassis’s true potential—sharper turn-in, more grip, better stability, and extended tire life. Whether you are building a daily-driven GT-R with a sporty edge or a track-focused weapon, investing in a matched coilover-and-arm package will transform your driving experience. Take the time to research products, plan your installation, and dial in the alignment. The result will be a GT-R that handles with surgical precision and responds instantly to your inputs, making every drive more engaging and satisfying.
