Product Description

The TEIN Street Advance Z Coilover Kit (Part No. GSP08-9USS2) is a performance-tuned suspension upgrade engineered for the 1999-2002 Infiniti G20 P11. This coilover set provides adjustable ride height and damping force control, allowing you to fine-tune your G20's stance and handling characteristics for spirited street driving or daily use. The Street Advance Z series builds on TEIN's well-known Super Street platform with Advance Needle technology that delivers more noticeable changes in damping force across its 16 adjustment stages.

Featuring corrosion-resistant ZT-coated threaded sleeves and powder-coated damper bodies, these coilovers are built for durability and long-term performance. Full-length dust boots help protect internal components from road debris, and the kit retains OEM upper mounts for straightforward installation. The optional EDFC (Electronic Damping Force Controller) allows in-car adjustment of damping settings (motor kit sold separately), making these coilovers a versatile upgrade for drivers seeking improved ride quality, reduced body roll, and a sportier stance.
