Product Description

The TEIN Street Basis Z Coilover Kit (Part No. GSR70-8USS2) is a ride-height adjustable suspension upgrade engineered for 2000-2005 Mitsubishi Eclipse models with D52A and D53A platforms, including GS, GT, GTS, RS, and Spyder variants. This entry-level coilover system enhances chassis control and stance while maintaining a comfortable daily-drive characteristic thanks to its twin-tube design and balanced spring rates. The threaded spring seats with TEIN's ZT coating allow you to precisely adjust your ride height for a more aggressive look or improved handling feel over stock suspension.

Built with corrosion-resistant powder-coated dampers and full-length dust boots, the Street Basis Z kit delivers durable performance for regular street use. While damping is not separately adjustable, the carefully selected spring rates and fixed damping tune offer a supportive yet compliant ride compared to factory shocks and springs. Reusing OEM upper mounts simplifies installation, making this a solid upgrade for Mitsubishi Eclipse owners seeking lowered stance and improved road feel without sacrificing everyday comfort.
