Product Description

The TEIN Street Basis Z Coilover Kit (Part No. GSMD0-8USS2) is a direct-fit suspension upgrade designed for the fourth-generation Mazda MX-5 Miata (ND/NDERC, 2016-2024) including both standard and RF body styles. This coilover set provides a simple way to lower your MX-5's ride height and achieve a sportier stance while enhancing handling stability over the stock suspension. The twin-tube design offers a comfortable street ride, making it well-suited for daily driving coupled with improved cornering response.

Ride height is fully adjustable via threaded lower spring seats, allowing drivers to fine-tune drop from mild to aggressive levels. The kit retains OEM upper mounts for straightforward installation, and its corrosion-resistant powder coating with robust dust protection ensures long-term durability. While damping is fixed, the progressive spring rates (6 kgf/mm front, 3.5 kgf/mm rear) provide a balanced feel between comfort and performance. This makes the Street Basis Z ideal for enthusiasts who want a noticeable improvement in handling and style without sacrificing everyday usability.
