Ohlins NIS MI31S1 Road & Track Coilover System Suspension Kit

The Öhlins NIS MI31S1 Road & Track Coilover System brings professional racing suspension technology to your street-driven vehicle without sacrificing daily driving comfort. This complete suspension kit features Öhlins' proprietary Dual Flow Valve (DFV) technology, allowing you to transform your car's handling characteristics instantly by simply turning the golden adjustment knob on each damper.

Dual Flow Valve (DFV) Technology:

The innovative DFV system enables quick stiffness adjustments between street and track modes. When you arrive at the track, turn the golden knob clockwise to activate race mode—this single adjustment simultaneously modifies all four damping characteristics: low-speed compression, high-speed compression, low-speed rebound, and high-speed rebound damping. This dual-mode capability ensures comfortable daily commuting while delivering race-ready performance when you need it.

Key Features:

• Height adjustable platform for precise ride height tuning
• Over 20 clicks of damping adjustment for fine-tuning
• Rebuildable shock absorbers for long-term serviceability
• Front spring rate: 160 N/mm for optimal response
• Rear spring rate: 90 N/mm for balanced handling
• Aluminum top mounts (front: non-adjustable; rear: spherical upper mounts included)
• Separate spring preload adjuster and length adjuster for independent ride height control
• Approximate 10mm ride height reduction versus stock with recommended setup
• ISO 9227 corrosion salt spray tested for durability
• 2-year worldwide limited warranty

Performance Benefits:

Experience dramatically improved response times, enhanced bump absorption, and significantly increased grip levels. The quick-reacting DFV components maintain tire contact with the road surface during both major and minor imperfections, improving vehicle balance and control at the limit. The system makes it easier to navigate corners with precision while maintaining composure on uneven surfaces.

What's Included:

Complete coilover kit with all necessary mounting hardware, aluminum front top mounts, spherical rear upper mounts, C-spanner tool for spring preload adjustment, owner's manual, and detailed mounting instructions. Note: EDC cancellation kit (part no. 35020-06) available separately for vehicles equipped with factory electronic damper control systems.
