1989-2005 Mazda Miata MX-5 NA / NB Traction Plus Ultra Coilovers

Bring sharper response and controlled balance to your 1989-2005 Mazda Miata MX-5 NA / NB with Riaction Traction Plus Ultra coilovers. Designed for lightweight rear-wheel-drive roadsters, the TPU system reduces body roll, stabilizes braking behavior, and delivers more predictable rotation through tight corners and rapid transitions.

Traction Plus Ultra is built around our new digressive piston design, engineered to provide firm low-speed damping for improved steering feedback and stronger roll resistance while maintaining compliance as suspension velocity increases. On the NA/NB chassis, this results in flatter cornering, improved mid-corner consistency, and more stable weight transfer without overwhelming the car’s naturally balanced character.

Each kit features a nickel-coated shock body for corrosion resistance and long-term durability. The hex screw preload collar locking system secures spring preload during repeated spirited driving. Signature orange-coated non-MacPherson components add durability and a distinctive performance finish, while pillowball upper mounts are included where applicable to maximize steering precision and suspension articulation.

Every Traction Plus Ultra system is backed by our 2-year factory warranty.
