Image: Diagram illustrating the process of adjusting coilover height by loosening lock rings and rotating the lower mount.
- Loosen the lower mount (A) and the locking ring (B) using the C spanners.
- Rotate the lower mount to increase or decrease the thread distance, thereby changing the ride height.
- Once the desired height is achieved, tighten the lower mount (A) and the locking ring (B) securely.
Important: Ensure both sides of the vehicle are adjusted evenly to maintain proper balance and handling.
7.2. DampAġġustament
These coilovers feature preset damping shock absorbers. While not explicitly stated as user-adjustable in the product description, some maXpeedingrods models offer damping adjustment.
