Engineered for the Mazda MX-5 Miata ND, the Riaction GP-1 Digressive Coilover Kit features digressive valving technology designed to complement the lightweight, driver-focused chassis of the Miata. This damping profile delivers firm low-speed control for sharper turn-in and reduced body roll, while maintaining compliance over uneven surfaces—resulting in a ride that feels precise, responsive, and balanced.

Built for enthusiasts who value driver feedback and control, this system enhances cornering stability, improves weight transfer characteristics, and maintains comfort for street driving while remaining capable for spirited and track use.

Each kit is constructed using high-quality materials and precision engineering to ensure durability, reliability, and consistent performance.
