Product Description

The TEIN Street Basis Z Coilover Kit (Part No. GSP92-8UAS2) is a ride-height adjustable suspension upgrade tailored for select RWD Infiniti and Nissan performance cars, including the G35 Sedan, G37 Coupe/Sedan, Q60, and 370Z. Designed as TEIN's entry-level coilover option, the Street Basis Z series focuses on balancing everyday comfort with improved handling and stance over stock suspension. With robust spring rates and a corrosion-resistant finish, this kit delivers a sportier look and feel while maintaining a compliant ride.

Unlike higher-end TEIN coilovers with adjustable damping, this Street Basis Z kit features fixed damping that's tuned for typical street use, making it easy to install and live with daily. Ride height is fully adjustable via TEIN's ZT-coated threaded seats, allowing you to dial in the stance you want without compromising reliability. OEM upper mounts are reused, simplifying installation, and full-length dust boots help protect damper shafts for long-lasting performance. Whether you're lowering for style or improved cornering confidence, this coilover set offers great value for enthusiasts seeking enhanced handling without harsh ride quality.
