Cusco 429 64R CP Sport R Coilover Kit 2016+ Mazda MX-5

The Cusco Sport R Coilover Kit delivers competition-grade suspension performance for the 2016+ Mazda MX-5 (ND5RC/NDERC chassis). Engineered for dedicated track use and motorsport applications, this monotube coilover system features pillow ball upper mounts, 24-way adjustable damping, and full-length height adjustment for precise handling tuning.

Key Features:

• Monotube construction for superior heat dissipation and consistent damping performance during extended track sessions
• 24-step adjustable rebound damping with Cusco's patented needle-valve system for precise tuning
• Pillow ball upper mounts eliminate rubber deflection for direct steering response and chassis feedback
• Full-length adjustable design allows height changes without affecting spring preload
• Track-focused spring rates optimized for competition compound tires and aggressive driving
• Coaxial length adjustment system for independent ride height tuning

The Sport R series represents Cusco's most aggressive street-legal suspension option, developed specifically for time attack, circuit racing, and serious track day enthusiasts. The monotube design provides a larger piston diameter and increased oil volume compared to twin-tube designs, delivering superior damping control at high piston speeds and improved fade resistance under repeated hard use.

Specifications:

• Shock absorber type: Monotube
• Damper adjustability: 24-way rebound adjustment
• Front upper mount: Non-adjustable pillow ball
• Rear upper mount: Non-adjustable pillow ball
• Height adjustment: Full-length coaxial adjustment front and rear
• Spring seat: Rubber

Optional accessories available separately include rigid aluminum spring seats and damper adjustment adapters for easier tuning access. This system is designed for drivers who demand uncompromising track performance and are willing to sacrifice some street comfort for maximum control at the limit.
