3. Prodotto finitoview e componenti
The maXpeedingrods coilover kit includes the following main components:
- Gruppi coilover anteriori (2)
- Gruppi coilover posteriori (2)
- C Spanners for Height Adjustment (2)
Caratteristiche principali:
- Molle ad alta resistenza: Front spring rate: 9 kg/mm (504 lbs/in). Rear spring rate: 10 kg/mm (556 lbs/in). These springs are tested for durability, showing less than 0.04% distortion after 600,000 continuous tests.
- Altezza regolabile: Allows for 1-3 inches of lowering, providing a more aggressive stance. Note: This kit does not maintain original ride height.
- Twin-tube Structure: Offers a longer stroke and higher height adjustment range compared to mono-tube designs, contributing to a more comfortable ride by reducing joint pressure and minimizing friction.
- Materiale durevole: Constructed from 6061 aluminum alloy with T6 for increased hardness, high quality precision parts, high strength, and durability.

4. Configurazione e installazione
Installation of coilovers requires mechanical expertise and specialized tools. It is strongly recommended that installation be performed by a certified automotive technician.
General Installation Steps (Consult a vehicle-specific service manual for detailed instructions):
- Sollevare e sostenere il veicolo in sicurezza. Rimuovere le ruote.
- Remove existing suspension components (struts, springs, etc.).
- Install the new maXpeedingrods coilover assemblies. Ensure all bolts are torqued to manufacturer specifications.
- Adjust the ride height as desired (refer to Section 5).
- Reinstallare le ruote e abbassare il veicolo.
- Perform a professional wheel alignment immediately after installation to prevent premature tire wear and ensure safe handling.
Importante: The coilovers are designed for a lowered stance and will not maintain the original ride height of your vehicle.
5. Funzionamento e regolazione
Regolazione dell'altezza di marcia:
The coilovers allow for a ride height adjustment range of 1 to 3 inches lower than stock. This adjustment is performed using the provided C spanners to rotate the locking rings on the coilover body.
- Safely lift and support the vehicle to relieve pressure from the suspension.
- 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: Il damping force of these coilovers is preset and not user-adjustable.

6. Manutenzione
Regular inspection and maintenance will ensure the longevity and performance of your coilovers.
- Ispezione regolare: Periodically inspect all coilover components for signs of wear, damage, or leaks. Check for loose bolts or nuts.
- Pulizia: Keep the coilover bodies and springs clean from dirt, salt, and debris, especially after driving in harsh conditions. Use mild soap and water.
- Controlli di coppia: After the initial installation and after approximately 500 miles, re-check the torque on all mounting bolts and nuts. Refer to your vehicle's service manual for specific torque values.
- Allineamento: If you notice uneven tire wear or changes in handling, have a professional alignment performed.
