BC Racing DS-SERIES Coilovers For 03-07 INFINITI G35 D-107-DS-DA

The BC Racing DS-Series Coilovers (SKU: D-107-DS-DA) are a premium coilover suspension kit engineered specifically for the 2003–2007 Infiniti G35 and the platform-sharing 2003–2008 Nissan 350Z. Built around BC Racing's proprietary digressive piston technology and a mono-tube shock design, the DS Series represents BC Racing's top-tier offering for enthusiasts who demand maximum driver feel, precise handling, and extensive on-car adjustability — whether on a spirited back-road drive or a weekend track day.

Key Features & Benefits

• Digressive Piston & Damping Curve: BC Racing's proprietary digressive piston design delivers increased damping force at low speeds for improved body control and composure, while remaining compliant enough over larger road imperfections — giving you the driver feedback of a track-focused setup without a punishing daily-drive experience.
• Mono-Tube Shock Construction: Unlike twin-tube designs, the mono-tube layout keeps shock oil and gas separated, reducing heat fade and maintaining consistent damping performance lap after lap or mile after mile.
• 30-Way Adjustable Damping: Fine-tune compression and rebound with 30 distinct damping clicks to dial in the exact ride quality and handling balance your driving style demands — from comfortable street cruising to aggressive track setups.
• Full Ride Height Adjustment: Independent spring perch and shock body adjustment allows you to set your desired ride height without compromising suspension travel or geometry, giving you the stance you want without sacrificing performance.
• Highly Customizable Platform: The DS Series is designed as a highly customizable suspension solution. The DA variant of this kit features an integrated rear configuration suited to the G35/350Z platform's rear suspension layout.
• True Coilover Design: Every corner is a genuine coilover assembly — no conversion kits or spring-over-shock compromises — ensuring consistent, predictable handling at all four corners.
• Made to Order in Japan: Each DS-Series kit is manufactured to order, reflecting BC Racing's commitment to quality control and precision fitment for your specific vehicle application.
