Product Details

The Riaction GT1 Coilovers for the 1990-2005 Acura NSX NA1/NA2 deliver a premium, adjustable suspension upgrade built for drivers who want more from their NSX NA1 than the factory setup can offer. These Acura NSX 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 track your NA1 NSX on weekends or log daily miles, this NA1 coilover kit dials in ride height and damping to match how you actually use 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 NSX NA1 to the height you want while preserving spring travel and shock stroke. Riaction coilovers for the 1990-2005 Acura NSX are fully rebuildable and backed by a 2-year warranty, making the GT1 a long-term suspension investment rather than a disposable upgrade.
