3. Key Features
The maXpeedingrods T7 Coilovers incorporate advanced features for optimal performance:
- Upgraded T7 Series: Features premium upgraded racing shock oil for stable handling across various temperatures and versatile racing springs suitable for both junior track and high-performance street use.
- 24 Levels Damper Adjustable: Allows for precise tuning of rebound force to match driving conditions and personal preference.
- Adjustable Lowering Height: Enables a ride height reduction of 1-3 inches from original, providing a more aggressive stance and improving steering feel and response.
- High Quality Construction: Most components, including mounts, collars, spring perches, and lock rings, are crafted from 6061-T6 billet aluminum for durability and rust resistance. Shock assemblies feature machined parts and an anti-corrosion finish with anodized aluminum and powder-coated carbon steel parts.
- Optimized Spring Rates: Front spring rate of 9kg/mm (504lbs/in) and rear spring rate of 7kg/mm (392lbs/in). Front spring length: 190mm (7.45inch), Rear spring length: 250mm (9.84inch). Both have a spring inner diameter of 70.5mm (2.78inch) with an advised spring preload of 7-10 mm.
- High Rigidity Piston Rod: Front rod diameter of 22mm ensures a long-lasting rod lifetime, achieved through high-frequency heat treatment for high rigidity and toughness to ensure safety.

4. Setup and Installation
Installation of coilovers requires specialized tools and automotive knowledge. It is highly recommended that installation be performed by a qualified professional to ensure proper fitment, safety, and optimal performance. Incorrect installation can lead to vehicle damage or unsafe driving conditions.
General Installation Steps (Professional Installation Recommended):
- Safely lift and support the vehicle on jack stands.
- Remove the wheels.
- Carefully remove the original suspension components.
- Install the new maXpeedingrods coilovers, ensuring all bolts are torqued to manufacturer specifications.
- Adjust the ride height as desired (refer to Operating Instructions).
- Reinstall wheels and lower the vehicle.
- Perform a professional wheel alignment after installation to ensure proper vehicle geometry.

5. Operating Instructions
The maXpeedingrods T7 Coilovers offer adjustable features to fine-tune your vehicle's ride and handling.
Damping Adjustment:
The coilovers feature 24 levels of rebound damping adjustment. This allows you to control the rate at which the shock absorber extends after compression, influencing ride comfort and handling responsiveness. The adjustment knob is typically located at the top of the coilover.
- Levels 0-8: Suggested for comfortable street use.
- Levels 9-16: Suggested for mountain roads or spirited driving.
- Levels 17-24: Suggested for occasional race use or maximum performance.
Height Adjustment:
The coilovers allow for ride height adjustment, typically by rotating the lower mount or spring perch. This enables you to lower your vehicle by 1-3 inches for a more aggressive stance and improved aerodynamics. Ensure the vehicle is safely supported before making height adjustments.

6. Maintenance
Regular maintenance is crucial for extending the lifespan and ensuring the continued performance of your coilovers.
- Regular Cleaning: Keep coilovers clean from dirt, salt, and debris, especially after driving in harsh conditions. Use mild soap and water, then rinse thoroughly.
- Inspect for Damage: Periodically check for any signs of leaks, corrosion, bent components, or damaged dust boots. Address any issues promptly.
- Check Torque Settings: Ensure all mounting bolts and lock rings remain properly torqued. Refer to your vehicle's service manual or a professional for specific torque values.
- Lubrication: If applicable, lubricate threaded sections with a suitable grease to prevent seizing and allow for easier height adjustments.
- Professional Inspection: Consider having your coilovers professionally inspected during routine vehicle maintenance, especially if you frequently drive on rough roads or participate in track events.
7. Troubleshooting
If you experience issues with your maXpeedingrods coilovers, consider the following common problems and solutions:
- Unusual Noises (Clunking/Squeaking):
- Cause: Loose mounting bolts, worn bushings, or improper spring preload.
- Solution: Check and re-torque all bolts. Inspect bushings for wear and replace if necessary. Verify spring preload is set correctly (7-10 mm advised).
- Poor Ride Quality (Too Stiff/Too Soft):
- Cause: Incorrect damping settings or improper spring rate for your driving style.
- Solution: Adjust damping settings (refer to Operating Instructions). If ride quality remains unsatisfactory, consult a professional to assess if different spring rates are needed for your specific application.
- Uneven Ride Height:
- Cause: Uneven height adjustment or settling of springs.
- Solution: Measure ride height at all four corners and adjust coilovers to achieve desired evenness. Ensure adjustments are made with the vehicle on a level surface.
- Leaking Shock Absorber:
- Cause: Damaged seal or internal component failure.
- Solution: A leaking shock absorber typically requires replacement. Contact customer support for assistance.
For persistent or complex issues, it is always best to consult with a certified automotive technician or maXpeedingrods customer support.
