NA NB Coilover Kit

The SuperMiata Tecna coilovers offer a balanced solution for Mazda MX-5 NA and NB models, bridging the gap between comfortable street driving and performance-oriented track use. These coilovers are engineered from scratch to deliver exceptional ride quality, allowing for lowered vehicle height while maintaining compliance over bumps thanks to their extended stroke and larger damper bodies. Constructed with CNC machined one-piece steel bodies and NA/NB Miata-specific aluminum end caps, the Tecna coilovers utilize a monotube design charged with high-pressure nitrogen and filled with Euro-spec synthetic fluid. They feature 30-position adjustable damping and adjustable ride height, with a recommended pinch weld height range of 4.75-6 inches (120-150mm). Buyers can select from two spring rate options: the 6/4kg/mm (336/224 in-lb) street setup for enhanced daily driving comfort, or the optional 9/6kg/mm (504/336 in-lb) sport rates for improved response and stability in autocross or light track conditions. Installation is facilitated by the fully assembled units with NB upper mounts, designed for a bolt-in fitment on all 1990-2005 Miatas. C-spanners are included for ride height adjustments. The manufacturer recommends setting the rear approximately 3mm higher than the front for optimal handling balance, with daily driven cars ideally set around 135mm. For those opting for the sport spring rates, pairing with a 24mm OEM rear anti-roll bar is suggested to further enhance handling feel. Supermiata's Tecna coilovers are designed for durability and low maintenance, backed by a 10-year limited warranty. They are shipped pre-adjusted and ready for installation, aiming to provide a significant upgrade in handling and ride quality for enthusiasts seeking a versatile suspension solution.
