D2 Racing D-NI-31 RS Series Coilover Kit Adjustable Monotube - 36-Way

The D2 Racing RS Series coilover kit (D-NI-31) is D2's flagship mid-level performance suspension system, delivering an ideal balance of street comfort and track capability. Built around a 36-way damping and rebound adjustable monotube shock design, this kit gives enthusiasts the tuning flexibility to dial in the perfect ride for everything from daily driving to occasional track days.

Unlike many competing coilovers, the RS Series features independent height and spring preload adjustments, allowing you to set your desired ride height without compromising full strut travel. Ride height can be lowered 60mm to 100mm from the OEM position. Front and rear units reuse the factory top mounts for a straightforward installation.

Key Features:

• 36-way damping and rebound adjustable monotube shock assemblies
• Full ride height adjustability with separate spring preload adjustment
• Maintains full strut stroke at all ride height settings
• Anodized and powder-coated mounts with anti-rust coating on strut threads
• SAE9254 steel springs to resist deformity; 6061 aluminum components resist corrosion
• CNC-machined construction to high manufacturing tolerances
• Front and rear reuse OEM top mounts
• Ride height drop range: 60mm–100mm from stock
• Fully rebuildable and serviceable in the USA
• 1-year manufacturer's warranty

The D2 Racing RS Series coilover kit is an excellent upgrade for the performance-minded driver seeking improved handling, a lowered stance, and the tuning versatility to adapt the suspension to changing conditions — all at an accessible price point.
