Race specification. 3-way adjustment. Maximum control on track.
The BC Racing ZX Series is a suspension system developed specifically for motorsport and intensive track use. With advanced 3-way damping adjustment and high-end internal components, the ZX delivers uncompromising control, repeatability, and durability under extreme conditions.

Technology & Construction

• Digressive piston and damping curve – strong low-speed control with smooth high-speed response
• Monotube design – stable and predictable damper performance
• Ultra-high viscosity index full synthetic shock fluid for consistent performance in extreme racing environments
• Dual piston design – precise separation of compression and rebound forces
• Fully rebuildable and serviceable construction

3-Way Damping Adjustment

• 30 clicks rebound adjustment
• 20 clicks low-speed compression adjustment
• 12 clicks high-speed compression adjustment

This wide adjustment range allows precise tuning to suit track layout, tyre setup, and driving style.

Performance Advantages

• Low-speed compression – controls body roll and weight transfer under braking and corner entry
• High-speed compression – absorbs kerbs and bumps without unsettling the chassis
• Rebound – manages suspension recovery to maintain traction and stability on corner exit

The result is higher cornering speeds, improved stability under heavy load, and maximum control over chassis balance.

Spring Rates

• 11 kg/mm front
• 7 kg/mm rear
• Custom spring rates available upon request

Compatibility

• Mazda MX-5 NC (2005–2015)
