MX-5 TEIN Street Basis Z Coilovers

TEIN Street Basis Z coilovers are a reliable, street-oriented suspension upgrade designed to improve handling and stance while maintaining excellent ride comfort. They are an ideal choice for daily-driven Miatas, offering TEIN quality and performance at an accessible price point.

The Street Basis Z features a sealed twin-tube damper design, allowing TEIN to reduce production costs without compromising ride quality or durability. The twin-tube construction provides a longer stroke, helping absorb bumps and road imperfections while maintaining stability during spirited driving. Compared to monotube dampers, twin-tube dampers are also more tolerant of minor external damage, as small dents to the outer shell do not affect internal piston movement.

Ride height is adjusted via a thread-type system, making it easy to fine-tune your Miata’s stance – from a subtle drop to a more aggressive street setup. Damping is factory-set and non-adjustable, allowing TEIN engineers to focus on a balanced setup optimized for street use without the need for additional tuning.

The kit is equipped with TEIN’s No-Sag linear springs made from cold-formed SAE9254 steel, ensuring consistent ride height over long-term use. High-quality damper oil with anti-foaming properties maintains stable performance across a wide temperature range. Corrosion-resistant coating and TEIN’s ZT-coated adjustment threads ensure long service life and smooth height adjustment.

Street Basis Z coilovers are best suited for street-driven cars that prioritize comfort, reliability, and simplicity over track-focused adjustability.
