RS-R 10+ Nissan 370Z (Z34) Sports-i Coilovers
PRODUCT INFORMATION
The RS-R Sports-i Coilovers are designed for drivers who want to blend daily comfort with aggressive street and occasional track performance. Built in Japan and engineered to exacting standards, the Sports-i series represents RS-R’s philosophy of crafting suspension that responds predictably and confidently across varying road conditions — without sacrificing ride quality.
Each Sports-i coilover is constructed with a mono-tube damper design, known for superior heat dissipation, faster response, and better damping consistency over long drives or spirited sessions. With 36-way adjustable damping, you can fine-tune rebound and compression characteristics to suit your exact driving needs — whether you're commuting, attacking mountain passes, or dialing in for an HPDE weekend.
Ride height adjustment is handled independently of preload, allowing you to preserve shock travel while customizing your stance. This is key for those who want a lowered look without compromising performance or shock longevity. The inverted damper design in many applications also improves chassis rigidity and keeps unsprung weight down — especially important for responsive cornering.
What separates RS-R from other suspension brands is their meticulous Japanese assembly and dyno-testing process, which ensures uniformity and damping curve accuracy for each individual damper. While some coilover systems are mass-produced, RS-R products are serialized, bench-tested, and carefully inspected before shipment. They're also tailored for specific Japanese and US-market vehicles, not generic rebranded systems.
