Take control of the high-revving V8 chassis dynamics in your 2006-2011 BMW M3 E90 / E92 with Riaction Traction Plus Ultra coilovers. Designed for performance-focused rear-wheel-drive platforms, the TPU system improves braking stability, reduces excessive body roll under heavy lateral load, and delivers more predictable rear traction during aggressive acceleration.

Traction Plus Ultra is engineered around our new digressive piston design, providing firm low-speed damping for stronger roll resistance and sharper steering precision while maintaining composure as suspension velocity increases. On the E9X M3 chassis, this results in improved mid-corner stability, flatter cornering under sustained load, and more consistent weight transfer during repeated hard 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, while pillowball upper mounts are included where applicable to maximize suspension articulation and steering feedback.

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