Show original supplier description
The TEIN Street Advance-Z Coilover Kit offers a balanced approach to performance suspension, suitable for both daily driving and spirited excursions. Designed to deliver a sporty ride feel and an aggressive aesthetic, this kit features 16-way adjustable damping to fine-tune your vehicle's handling characteristics. The construction utilizes durable steel with a twin-tube internal design for consistent performance. Ride height adjustability is managed through the spring seat, allowing for customization of your vehicle's stance. The kit includes four shock absorbers, four springs with rates of 392 lbs/in front and 336 lbs/in rear, along with all necessary hardware such as seat locks, spring seats, thrust washers, bump rubbers, dust covers, and hook spanners. A comprehensive instruction manual is included to guide installation. The kit is designed for Mazda MX-5 Miata models from 1990-2005 (NA and NB series).
