2014-2020 BMW M3 / M4 F80 / F82 / F83 (3-Bolt) Traction Plus Ultra Coilovers

Dial in precise chassis control and consistent load management in your 2014-2020 BMW M3 / M4 F80 / F82 / F83 (3-Bolt) with Riaction Traction Plus Ultra coilovers. Designed specifically for 3-bolt top mount configurations, the TPU system improves braking stability, reduces body roll under heavy lateral load, and delivers more predictable rear traction during aggressive acceleration.

Traction Plus Ultra is built around our new digressive piston design, engineered to provide firm low-speed damping for stronger roll resistance and sharper steering precision while maintaining composure as suspension velocity increases. On the F8X chassis, this translates into improved mid-corner stability, flatter cornering under sustained load, and greater consistency during repeated high-performance driving.

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 track use and high-load conditions. Signature orange-coated non-MacPherson components add protection and a distinctive performance finish. Pillowball upper mounts are included where applicable and designed to integrate properly with the 3-bolt mounting setup for maximum steering precision and suspension articulation.

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