2. Components
The Tein Street Basis Z Coil Over system utilizes a sealed structure design, which contributes to its enhanced durability and simplified maintenance. Unlike repairable units that involve disassembling multiple parts, the sealed structure is a fixed unit, reducing the potential for issues related to component wear and tear.

3. Setup and Installation
Installation of suspension components requires specialized tools and knowledge. It is highly recommended that installation be performed by a qualified professional technician. Improper installation can lead to vehicle damage, poor performance, or safety hazards.
General Installation Guidelines:
- Vehicle Preparation: Safely lift and support the vehicle on a level surface using appropriate jack stands. Ensure the vehicle is stable before proceeding.
- Wheel Removal: Remove the wheels from the vehicle.
- Original Suspension Removal: Carefully remove the original shock absorbers and springs, following the vehicle manufacturer's service manual. Note the orientation and position of all components.
- Coil Over Installation: Install the Tein Street Basis Z Coil Over units. Ensure all mounting points are correctly aligned and fasteners are torqued to the vehicle manufacturer's specifications.
- Ride Height Adjustment: Adjust the ride height as desired using the provided adjustment wrenches. Ensure the vehicle is on a level surface for accurate measurement.
- Final Checks: Reinstall wheels, lower the vehicle, and perform a final inspection of all installed components.
- Alignment: After installation, a professional wheel alignment is mandatory to ensure proper vehicle handling and tire wear.
4. Operating
After installation, allow for a break-in period of approximately 100-200 miles. During this time, avoid aggressive driving to allow the suspension components to settle. Monitor for any unusual noises or handling characteristics. The Street Basis Z coil overs are designed for a fixed damping rate, providing a consistent ride quality. Ride height can be adjusted to suit personal preference and driving conditions.
5. Maintenance
Regular maintenance is crucial for the longevity and performance of your Tein Street Basis Z Coil Over system.
- Regular Inspection: Periodically inspect the coil overs for any signs of damage, leaks, or corrosion. Check rubber boots and bushings for cracks or wear.
- Cleaning: Keep the coil over bodies clean, especially after driving in harsh conditions (e.g., snow, salt, dirt). Use mild soap and water, then rinse thoroughly.
- Fastener Torque Check: After the initial break-in period and periodically thereafter, check the torque of all mounting bolts and nuts to ensure they are tightened to specification.
- Ride Height Adjustment Threads: If adjusting ride height, clean the threads before and after adjustment to prevent dirt buildup.
6. Troubleshooting
If you experience any issues with your Tein Street Basis Z Coil Over system, consider the following common troubleshooting steps:
- Unusual Noises: Check all mounting points for proper torque. Inspect for any loose components or contact between the coil over and other vehicle parts.
- Uneven Ride Height: Ensure ride height adjustments are consistent on both sides of the vehicle. Verify that the vehicle is on a level surface when measuring.
- Poor Handling: Confirm that a professional wheel alignment was performed after installation. Check tire pressure and condition.
For persistent issues or concerns, it is recommended to consult with a professional automotive technician or contact Tein customer support.
