Feature

1. Lowered height adjustment from 25-75mm (depends on vehicle models) which allows a lower center of gravity and also adds a more aggressive stance 
2.24 levels of adjustable damper -- This allows you the ability to perfectly dial in your coil-overs system. For nice comfortable driving, set damping to full soft. For more spirited driving, set it to 16 clicks. For occasional track days, set it to full stiff.
3. Adjustable pre-load spring tension to reduce the shaking motion to a certain extent
4. Adjustable Camber Plate and Pillow ball top mount for sharpening steering response. ( for some models)
5. CNC machined Aluminum  top mounts and lockers-- - excellent strength, and save weight
6. Heavy Duty Steel Lower Mounts--- Highly Durable & Reliable
7. High tensile spring---  600,000 times continuously test to assure its high tensile strength.
8. All inserts come with fitted long rubber boots--- To protect the damper better and be durable.
9. Twin-Tube structure ---provides excellent handling & control characteristics for most driving conditions
10. Corrosion Finish - Anodized Aluminum And Powder Coated Carbon Steel Parts

Note:

1. All modifications must be installed by licensed mechanics and in compliance with your local modification regulations.
2. Please ensure all components are tightened with correct torque specifications (which can be found in the vehicle service manual)before and after installation. Any loose nuts, bolts, or locks will cause noise. Do check and tighten before serious problems happen. 
3. Impact wrench is prohibited during the installation, it will loosen or damage the product.
4. Examine the clearance between tires and suspension. ( The minimum clearance should be 4mm, otherwise, you need to add wheel spacers. Caution: It is not sufficient with torsion beam trailing arm axles)
5. We suggest regular maintenance for the coil-over, spray with some WD40 every 3-4 months will keep it smooth and clean, which helps to extend the lifetime.
