Product Details
The Riaction GT1 Coilovers for the 1989-2005 Mazda Miata NA/NB deliver a premium, adjustable suspension upgrade built for Miata drivers who want more from their car than the factory setup can offer. These Mazda MX5 coilovers are engineered to pair street comfort with canyon and track capability, giving you the stance, handling, and adjustability you've been chasing without compromising daily driveability. Whether you autocross your NA or log daily miles, this NA Miata coilover kit dials in ride height and damping to match how you actually drive the car.
Every GT1 set features a monotube damper with 32 levels of damping adjustment, so you can tune ride quality to match the road, the weather, or your driving mood. Full-length ride-height adjustment separates preload from ride height — meaning you can drop the Miata to the height you want while preserving spring travel and shock stroke. Riaction coilovers for the 1989-2005 Mazda Miata MX5 are fully rebuildable and backed by a 2-year warranty, making the GT1 a long-term suspension investment for your Mazda Miata rather than a disposable upgrade.
