Mazda MX5 NA/NB (89-05) BC Racing BR Series Coilover

Built around a robust monotube damper design with a larger 46 mm piston in a 53 mm damper body, these coilovers increase oil capacity to reduce peak damper temperatures and maintain consistent performance under extended hard use. 

What Makes the BR Series Great?

• Adjustable Ride Height: Set your car’s look and performance exactly how you want it without affecting spring preload or damper travel.  
• 30-Way Damping Adjustment: Tunable between soft to firm in 30 steps for tailored handling and comfort.  
• Durable Monotube Dampers: Improved oil flow and heat dissipation for consistent damping.  
• High-Quality Springs: Cold-wound SAE9254 spring steel rated for over 500,000 compression cycles with minimal fatigue.  
• Tinted Corrosion Protection: Anodised aluminium parts and coated steel components for long-term durability.  
• Optional Camber-Adjustable Pillowball Mounts: Where applicable, top mounts are equipped for camber fine-tuning.  
• Patented Lower Locking Collar: Ensures the bottom mount stays secure and ride height stays where you set it.  
• Complete Serviceability: Rebuildable design with spare parts widely available.

Whether you’re chasing tighter turn-in on backroads, reducing body roll on canyon sweeps, or simply lowering your ride with confidence and control, the BR Series strikes a strong balance between performance and everyday usability.
