1986-1991 Mazda RX-7 FC3S Traction Plus Ultra Coilovers

Refine the balance and steering clarity of your 1986-1991 Mazda RX-7 FC3S with Riaction Traction Plus Ultra coilovers. Developed for lightweight rear-wheel-drive sports cars, the TPU system improves front-end response, stabilizes chassis movement under braking, and delivers more predictable rear traction during aggressive cornering.

Traction Plus Ultra is centered around our new digressive coilover piston design, engineered to provide firm low-speed damping for improved roll control and sharper steering input while remaining composed as suspension velocity increases. On the FC3S chassis, this translates into smoother transitional behavior, stronger mid-corner stability, and greater confidence when driving at the limit.

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 under repeated hard driving. Signature orange-coated non-MacPherson components provide added protection 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.
