TEIN Street Advance Z Coilover Suspension Kit

The TEIN Street Advance Z coilover suspension kit (also called a coilover spring and shock assembly or adjustable coilover kit) is a street-focused suspension upgrade. It is built for drivers who want a lower, sportier stance and sharper handling without giving up daily-driving comfort. TEIN is a respected Japanese suspension manufacturer. This product line is aimed at both everyday and spirited driving.

Key Features:

• 16-way damping force adjustment lets you tune ride firmness to your driving style and road conditions
• Height-adjustable design. Moving the lower spring seat up or down sets ride height and makes corner leveling simple
• Twin-tube damper construction gives a longer stroke with lower repulsive force, for a smooth ride over rough roads and stability at higher speeds
• Fully sealed damper structure. The narrow shell pipe allows oil and gas to be injected before the body is sealed
• Shortened shell case keeps good damper stroke at ride heights lower than stock
• Corrosion-resistant finish and steel construction help extend service life
• EDFC compatible. The kits work with TEIN's optional electronic damping force controller for in-cabin adjustment

These kits are designed to lower the center of gravity, reduce body roll, and improve handling and looks. Many applications reuse the factory upper mounts. Dampers in this line are not designed to be rebuilt. A professional alignment is recommended after installation, since changing ride height affects camber and toe.
