Show original supplier description
The HSD Dualtech coilover kit is engineered as a significant upgrade over OEM suspension for the Mazda RX-7 FC3S models from 1985 to 1992. This kit provides a superb balance of performance, adjustability, comfort, and value for money, making it an excellent choice for both street driving and stylistic enhancements. Each coilover is designed as a perfect, bolt-on fit, eliminating the need for additional vehicle modifications during installation. Key features of the Dualtech kit include 14-way adjustable twin-tube dampers, allowing for precise tuning of the ride to suit daily driving or track use. The front springs are rated at 8K (200mm - 65mm ID) and the rear springs at 6K (200mm - 65mm ID). Adjustment capabilities extend to ride height, damping, and front camber. Developed in collaboration with HSD and Driftworks, these coilovers have been tried, tested, and proven on various road, track, and drift cars since 2007.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout.
