Tein's Street Advance Z brings the same materials and build quality as their higher-tier Flex Z kit down to a more street-focused package, minus the adjustable camber top mounts. It's built for drivers who want a genuine ride height drop and sharper handling without giving up everyday comfort.

A twin-tube damper design is the heart of what makes this kit livable on the street — compared to a mono-tube setup, it delivers a longer stroke with less repulsive force, so you get a smoother ride over rough pavement at low speed while staying composed and stable at higher speeds. Ride height adjusts via a simple thread-type lower spring seat, and because the kit uses your Civic's original upper mounts, installation stays straightforward.

Features

• Twin-tube damper design for a longer stroke and more comfortable ride than mono-tube setups
• Thread-type ride height adjustment via the lower spring seat
• Uses factory OE upper mounts — no camber adjustment included
• No-sag springs cold-formed from SAE9254 steel with durable powder coating
• High-performance damper oil holds stable viscosity across a broad temperature range, resists cavitation and long-term degradation
• Dust boot protects the piston rod from damage and debris
• TEIN-Green 2-layer, 1-bake powder coating on the shock body for corrosion resistance
• ZT Coating on the ride height adjustment thread resists abrasion and corrosion — proven rust-free across 500,000+ shocks in the field
