- Loosen the upper locking ring using a C spanner.
- Rotate the lower spring perch to achieve the desired ride height. Turning clockwise will lower the vehicle; counter-clockwise will raise it.
- Once the desired height is set, tighten the upper locking ring against the lower spring perch to secure the adjustment.
- Repeat for all four coilovers, ensuring consistent height settings across the axle (front left/right, rear left/right).
- Lower the vehicle and bounce the suspension to settle it. Re-check ride height and adjust as necessary.
Nota: damping force of these coilovers is preset and not user-adjustable.
