Product Description

The TEIN Street Advance Z Coilover Kit (GSB78-9USS2) is engineered to provide a balance of sporty handling, ride comfort, and affordability for the Honda Accord and Acura TSX platforms. Built with a twin-tube damper architecture, this suspension system improves ride stability and responsiveness while maintaining smooth daily-driving characteristics. The 16-way adjustable damping allows drivers to fine-tune suspension firmness to suit both daily commuting and spirited driving.

Ride height is adjustable through a threaded spring seat design, allowing the vehicle to achieve a more aggressive stance while improving cornering dynamics. Typical lowering ranges reach approximately 16-98 mm in the front and 11-72 mm in the rear depending on vehicle configuration and setup. Constructed with durable steel components, corrosion-resistant ZT-coated threads, and high-tensile SAE9254 springs, the kit is designed for long-term durability while retaining factory upper mounts for easier installation.
