Ohlins MAS6I30 Road & Track DFV Rear Shock Absorber for Mazda MX-5 Miata NC

The Öhlins MAS6I30 is the rear shock absorber from the Öhlins Road & Track coilover system, engineered for the 2006–2014 Mazda MX-5 Miata (NC chassis). Built on decades of Öhlins motorsport expertise, this aluminum monotube damper delivers a refined balance of track performance and everyday street comfort that stock suspension simply cannot match.

At the core of this shock is Öhlins' proprietary Dual Flow Valve (DFV) technology, which automatically responds to increased shaft speeds to keep tire contact with the road surface optimized under all driving conditions. A single 30-position damping adjuster allows the driver to dial in the desired feel from a refined street ride to aggressive track-day firmness without complicated setup procedures.

Key Features:

• DFV (Dual Flow Valve) Technology — optimizes tire contact and chassis control across varying road conditions
• Aluminum monotube damper construction — lightweight and thermally efficient for consistent performance
• 30-position single damping adjuster — easy tuning between soft street and firm track settings
• Rear spring rate: 40 N/mm (229 lbs/in.) — model-specific tuning for the NC Miata platform
• Ride height adjustable — height adjustment range of -10mm to -40mm from stock (-35mm nominal)
• Spring preload adjustable independent of ride height — maintains suspension travel and prevents topping out
• Uses original OE rear top mount — straightforward fitment with no additional hardware required
• Rubber dust boots included — protects damper internals from debris and contamination
• Rebuildable and serviceable in the USA — long-term investment in suspension performance
• Corrosion salt spray tested to ISO 9227 — proven durability in harsh conditions
• DOT and TÜV approved — meets stringent safety standards
• 2-year limited warranty

The MAS6I30 rear shock is designed for the NC-generation Mazda MX-5 Miata driver who wants precision handling at the limit without sacrificing day-to-day ride quality. Whether commuting, running autocross, or logging track days, Öhlins Road & Track suspension delivers a measurable upgrade in chassis control, stability, and driver confidence.
