Refine the driving dynamics of your 1999-2005 BMW 3 Series E46 RWD Non-M with Riaction Traction Plus Ultra coilovers. Designed for rear-wheel-drive sport sedans and coupes, the TPU system improves braking stability, reduces excessive body roll, and delivers more consistent rear traction during spirited driving.

Traction Plus Ultra is engineered around our new digressive piston design, providing firm low-speed damping for stronger roll resistance and clearer steering feedback while maintaining composure as suspension velocity increases. On the E46 chassis, this results in flatter cornering, smoother transitional response, and improved mid-corner stability without sacrificing everyday comfort.

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 hard driving. 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 precision.

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