Introduction text: This article presents five coilover kits commonly used on the G35 and 350Z platforms, emphasizing damping adjustment, ride height range, and durability. Each entry includes a concise product snapshot and how it can affect handling, cornering stability, and everyday comfort. This helps buyers compare multiple perspectives—precision tuning for track days, a balanced street setup, or a forgiving ride with sport styling.
BC Racing BR True Rear Coilovers For G35/G35/350Z
BC Racing’s BR True Rear Coilovers are designed for the 2003–2009 Infiniti G35 and 2003–2009 Nissan 350Z. The system features 30 levels of damping adjustment, enabling precise control over compression and rebound to suit street driving, weekend cruising, or track sessions. Height adjustment is independent of spring compression, allowing you to achieve a more aggressive stance without compromising comfort. The mono-tube shock design adds durability, and dust boots protect the internals, with full rebuildability ensuring long-term serviceability and value.
Users can expect improved turn-in response and flatter cornering once the damping is tuned to their preferred balance of comfort and performance. The BR series is known for a reliable rebuild path, making it a practical long-term upgrade for enthusiasts who want consistent performance over time.
maXpeedingrods Coilovers For 350Z / G35
maXpeedingrods offers a height-adjustable coilover kit compatible with Nissan 350Z and Infiniti G35 models (RWD, excluding AWD). The height adjustment allows a 1–3 inch drop to achieve a more aggressive stance and improved steering response while attempting to minimize turning noise. The kit maintains a factory-preserving damping value, providing predictable handling and consistent performance. It’s positioned as a practical upgrade for drivers seeking a sportier look without sacrificing too much daily comfort.
Key consideration: this setup is not intended for AWD variants, so buyers with all-wheel-drive configurations should select alternative configurations. The kit emphasizes a balance between aggressive styling and responsive handling, suitable for street-driven enthusiasts who want a more planted feel in corners and reduced body roll with proper alignment.
Rev9 Hyper-Street II Coilover Kit (G35)
Rev9’s R9-HS2-008_2 Hyper-Street II coilover kit is a popular option for the Infiniti G35 Coupe (V35) and related models. It features a true coilover conversion on the rear strut, with spring rates specified for front and rear (14 kg/mm front, 12 kg/mm rear) and 32-way damping adjustment. This setup aims to deliver a higher level of control on track days while providing stable daily drivability. The included coil springs over shock design is intended to lower the vehicle in a controlled and balanced manner, helping reduce squat under braking and improve mid-corner stability.
Pros include a wide damping range that supports both street and track use, and the true coilover rear conversion that can improve rear wheel traction and overall chassis balance when combined with proper alignment settings.
Truhart StreetPlus Coilovers (03-07 350Z / G35)
Truhart StreetPlus Coilovers are a straightforward, street-oriented suspension upgrade for 2003–2007 models of the 350Z and G35. They provide height adjustment and ride-height customization to establish a sportier stance, along with reliable damping performance appropriate for daily driving and occasional spirited driving. The StreetPlus line emphasizes a balanced, predictable feel rather than extreme track-focused rigidity, making them a solid choice for enthusiasts who want improved handling without sacrificing daily comfort.
Performance note: With adjustable ride height, owners can tailor cornering behavior and steering response. The setup is designed to offer easy adjustments and reliability, which is helpful for drivers who want a simple, consistent upgrade path.
Godspeed MSS0270-B MonoSS Coilover Kit
The Godspeed MSS0270-B MonoSS coilover kit is designed to optimize handling for Infiniti G35 models with full mono-tube shock technology. It offers 16 damping levels to accommodate varying driving scenarios from daily commuting to occasional track days. The kit supports a lowering range suitable for a lowered stance and improved aerodynamics, making it a versatile option for drivers seeking a balanced upgrade that can adapt to different road conditions.
Key considerations include the damping range and the durability of the mono-tube design, which typically performs well under sustained driving conditions and provides predictable adjustments as suspension geometry changes with lowering.
Buying Guide: Key Purchase Considerations
When selecting coilovers for a G35 or 350Z, buyers should weigh several factors to align with goals and daily usage.
- Intended use: Street only vs. track days. Choose damping ranges and spring rates that balance comfort with performance.
- Height adjustment vs. damping: Some kits emphasize height adjustment independently, while others focus on broad damping ranges. Consider which feature matters most for your goals.
- Ride quality: Mono-tube designs often offer better heat management and consistent performance under load, but may transmit more road feel than twin-tube setups.
- Durability and rebuildability: Kits with rebuildable shocks and accessible replacement parts tend to offer longer-term value, especially for avid enthusiasts.
- Compatibility: Ensure the kit supports your model year and drivetrain configuration (RWD vs AWD).
- Wheel fitment: Lowering can affect tire clearance, suspension geometry, and alignment limits. Plan for alignment and potential rubbing with wheels and fenders.
- Maintenance footprint: Regular inspections of mounts, bushings, and seals help maintain performance over time.
Comparison snapshot: If you prioritize maximum damping customization and rebuildability, the BC Racing BR line offers extensive adjustment and long-term serviceability. For a balance of street usability and a more aggressive stance, maXpeedingrods and Truhart StreetsPlus deliver practical options. Rev9 Hyper-Street II and Godspeed MonoSS provide broad damping choices with distinct rear coilover conversions, suitable for drivers seeking a tighter chassis feel without a radical ride harshness. Always pair coilovers with proper alignment, corner weight distribution checks, and appropriate tires to extract the best handling improvements.
