1999-2005 BMW M3 E46 Traction Plus Ultra Coilovers

Bring precise chassis control and high-load stability to your 1999-2005 BMW M3 E46 with Riaction Traction Plus Ultra coilovers. Designed for one of BMW’s most iconic rear-wheel-drive performance platforms, the TPU system improves braking composure, reduces 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 E46 M3 chassis, this results in flatter cornering, improved mid-corner balance, 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 under sustained high-load use. Signature orange-coated non-MacPherson components add 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.
