Introduction: Beyond the Godzilla Legend

The Nissan GT-R earned its "Godzilla" nickname by delivering supercar-slaying performance at a relative bargain. Its ATTESA E-TS all-wheel-drive system and sophisticated Bilstein DampTronic suspension allow it to put power down with ferocious efficiency. However, even the best factory setup represents a compromise between comfort, compliance, and outright track capability. For the enthusiast who wants to extract the last tenths of a second on a circuit or sharpen that cornering response for high-speed canyon runs, targeted suspension upgrades are the single most effective path to improvement.

Upgrading the suspension does more than just lower the car. It changes how weight transfers, how the tires maintain contact with the pavement, and how the chassis communicates with the driver. This article will dissect the key suspension upgrades for the R35 GT-R, explaining the engineering principles behind each component and guiding you toward a setup that matches your driving goals, whether that's daily-driven street duty or dedicated time-attack work.

Understanding Suspension Fundamentals for the GT-R

Before selecting parts, it's critical to understand what the suspension actually does. The GT-R's independent double-wishbone front and multi-link rear suspension is geometrically capable, but its components are tuned for a broad audience. Key parameters include:

  • Spring Rate: The force required to compress the spring. Higher rates reduce body roll but can compromise ride quality and require matching damping.
  • Damping: The resistance to spring movement. Good damping controls oscillations and keeps the tire planted after bumps or during weight transfer.
  • Roll Center & Geometry: The location of the roll center changes with ride height. Drastically lowering a GT-R without correcting geometry can lead to bump steer, camber loss, and unpredictable handling.
  • Unsprung Weight: Components not supported by the springs (wheels, tires, brakes, control arms). Reducing unsprung weight improves suspension response.

The factory GT-R suspension, while capable, is tuned for a slightly understeer-biased balance. Many upgrades aim to introduce neutrality or even a progressive tendency toward oversteer for more aggressive corner entry. A holistic upgrade path addresses all these areas, not just one.

Critical Suspension Upgrades for the Nissan GT-R

The following upgrades represent the most impactful changes you can make. Each component works in concert; combining them yields far greater benefits than any single part.

Coilover Systems: The Foundation of Handling

Coilovers are the most comprehensive single upgrade. They replace the entire strut assembly with a spring-over-shock unit, allowing independent adjustment of ride height and, on higher-end units, compression and rebound damping. For the R35 GT-R, top-tier options include Öhlins Road & Track or Flagship series, which offer remote reservoirs and individual piston adjustments. KW Suspensions offers the Clubsport and V5 series with hydraulic bump-stop technology, ideal for aggressive track use. Nitron R3 Street/Track and BC Racing ER series provide excellent value with solid performance.

Key benefits of a quality coilover upgrade:

  • Lower Center of Gravity: Dropping the GT-R 20-30 mm dramatically reduces weight transfer during cornering.
  • Precise Damping Control: Track-focused damping curves control the chassis on curb strikes and during high-speed transitions.
  • Corner Weighting: Fine adjustment of each corner's ride height allows exact corner balancing, improving entry and exit traction.
  • Spring Rate Selection: Most kits offer multiple spring rates. A common track setup for the GT-R is 12-14 kg/mm front and 14-16 kg/mm rear, but this should be matched to tire grip and driving style.

When selecting coilovers, pay attention to valving compatibility with GT-R's weight distribution (approximately 55% front). A poorly valved coilover set can be harsh without improving grip. Professional installation and setup are mandatory—a spring that is too stiff without proper rebound damping will skip over bumps, reducing traction.

Anti-Roll Bars (Sway Bars): Taming Body Roll

The GT-R is a heavy car, weighing around 3,800 lbs. That mass generates significant body roll in corners, which unloads the inside tires and limits ultimate grip. Upgrading the front and rear anti-roll bars is one of the most cost-effective ways to reduce roll without sacrificing ride quality as much as high-rate springs.

A stiffer front bar reduces front body roll, which improves turn-in response but can also increase understeer if too stiff. Conversely, a stiffer rear bar reduces rear roll and can promote oversteer, helping rotate the car through tight corners. Many GT-R owners find a combination of a stock or slightly stiffer front bar and a significantly stiffer (adjustable) rear bar, such as the Hotchkis Sport Sway Bar System or Whiteline adjustable sway bars, allows fine-tuning of balance. Adjustable bars let you dial in stiffness across multiple settings.

Important note: Upgrading sway bars changes the load transfer distribution but does not increase total grip—it changes the balance. Always pair sway bars with upgraded end links (preferably spherical bearing types for zero deflection) to take full advantage of the stiffer bar.

Control Arms, Bushings, and Geometry Correction

Lowering the GT-R even 15 mm alters the suspension geometry significantly. The front roll center drops below ground level, causing extreme camber gain under compression and promoting bump steer. To correct this, adjustable control arms and kit components are essential.

  • Front Upper Control Arms (SUCA): These arms allow camber and caster adjustment. More negative camber (typically -2.5 to -3.0 degrees on track) maximizes tire contact patch during cornering. Increased caster improves steering feel and dynamic camber. Brands like SPL Parts and Greddy offer high-quality billet adjustable arms.
  • Rear Camber & Toe Arms: The rear multi-link suspension also shifts geometry when lowered. Adjustable arms restore alignment to within spec and allow aggressive camber settings for high-speed stability.
  • Bushings & Spherical Bearings: Factory rubber bushings deflect under heavy loads, introducing slop and unwanted toe/camber changes. Replacing critical bushings with polyurethane (for street compliance) or spherical bearings (for zero deflection on track) sharpens response. The Voodoo13 or AMS Performance bushing kits address the compliance in the lower control arms and subframe mounts.

Geometry correction is not optional for a lowered GT-R intended for high-performance driving. Without it, the car will be unpredictable and may wear tires prematurely.

Chassis Bracing and Strut Braces

The R35's chassis is already stiff for a production car, but it still flexes during extreme cornering loads. A strut tower bar (front strut brace) connects the two front towers, reducing chassis twist and improving steering precision. The Cusco or Nismo braces are popular. For more serious track work, a full chassis brace kit (like the Do-Luck subframe braces or Carbing body rigidity bars) triangulates the floor and rear subframe. These additions reduce the sensation of chassis shudder and allow the suspension to work more consistently.

High-Performance Shock Absorbers (If Keeping OEM Springs)

If you're not ready for full coilovers, replacing the factory Bilstein DampTronic shocks with aftermarket units like Tein Street Advance Z or Bilstein B16 PSS10 can provide improved damping control while retaining electronic adjustment features (on compatible models). However, these still rely on factory-style springs and may not allow the ride height adjustment of true coilovers. For most performance enthusiasts, coilovers remain the better route.

Spring Rates, Ride Height, and Corner Balancing

Choosing the correct spring rate is a balancing act. Too soft, and the car will roll excessively, losing tire contact. Too stiff, and the suspension cannot absorb bumps, leading to wheel hop and loss of traction.

A good starting point for a dual-purpose GT-R is 10 kg/mm front and 12 kg/mm rear. For a dedicated track car, 14-16 kg/mm front and 16-18 kg/mm rear work well with sticky tires (like Yokohama Advan A052 or Toyo R888R). The GT-R's heavier rear end (due to rear transmission) benefits from a slightly stiffer rear spring to control squat under acceleration and improve rotation.

Corner balancing is the process of adjusting ride height at each corner so that the car's weight is distributed evenly across the diagonal pairs. A professionally corner-balanced GT-R will have better mid-corner stability and more predictable limit behavior. This service is essential after any ride height change and should be performed by a race shop with experience on the R35.

Daily Driving vs. Dedicated Track Setup

Not every upgrade is appropriate for a car that sees weekly commutes and occasional spirited drives. Here is how to differentiate your setup:

Daily Driver Focused

  • Coilovers: Choose a street-oriented kit like the KW V3 or Öhlins DFV with moderate spring rates (8-10 kg/mm). Adjustable damping allows a compliant ride for rough roads.
  • Sway Bars: Use adjustable bars set to soft or medium. Avoid spherical bearing end links if they transmit too much noise.
  • Bushings: Stick with polyurethane in critical areas (front lower control arms). Full spherical bearings can introduce harshness.
  • Alignment: Aim for -1.5 to -2.0 degrees front camber (street tires) and zero to slight toe-in for stability. Less aggressive than track settings.

Track Performance Setup

  • Coilovers: Dedicated track units with high spring rates (14+ kg/mm), monotube dampers, and external reservoirs for heat dissipation. Nitron R3 or Motorsport Tech are common.
  • Sway Bars: Maximum stiffness setting, often paired with upgraded end links and maybe a rear bar that is stiffer than front to induce rotation.
  • Bushings: Spherical bearings everywhere possible—zero deflection.
  • Geometry: -3.0 degrees front camber, -1.5 degrees rear, aggressive toe-out front for turn-in, slight toe-in rear for stability.
  • Additional: Consider a roll center correction kit (like SPL Roll Center Adjusters) to prevent bump steer.

If your car sees a mix, opt for the daily-driven setup but with adjustable components that allow quick camber and damping changes for track days. The extra 30 minutes spent adjusting alignment before a track day is well worth it.

Installation, Alignment, and Professional Setup

Suspension upgrades for the R35 GT-R are not bolt-and-go. The complexity of the ATTESA system requires careful attention to sensor recalibration, ABS system checks, and corner weighting. A proper installation includes:

  • Pre-loading suspension bushes: All control arm and bushing bolts must be tightened with the car at ride height (wheels on ground) to prevent premature bushing failure.
  • Height and preload adjustment: Coilovers must have correct spring preload to ensure full droop travel.
  • Professional 4-wheel alignment with corner balance: Use a shop that has experience with the R35's specific cross-weight targets. Many good shops use a Hunter DSP600 or similar alignment rack and a corner weight scale.
  • Damping adjustments: Start with manufacturer baseline settings, then fine-tune on a skidpad or controlled road course environment.

Conclusion: Building a Cohesive Suspension

Upgrading the Nissan GT-R's suspension is about creating a cohesive system where springs, dampers, sway bars, and geometry corrections work in harmony. The stock GTR is already incredibly capable, but with targeted upgrades—especially coilovers with proper spring rates, adjustable control arms for geometry correction, and sway bars to fine-tune balance—you can unlock a level of cornering grip and stability that rivals far more exotic machinery.

Begin with your driving goals: prioritize adjustability for a dual-use car, or uncompromising stiffness for a track weapon. Invest in professional installation and corner weighting; it makes more difference than the parts themselves. With the right setup, your GT-R will not only carve corners with surgical precision but also offer a more engaging and confidence-inspiring driving experience, whether you're chasing lap times or simply enjoying a twisty road.
