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.
