BMW E46 Bilstein B12 Pro-Kit (46-180049) - Fast Road & Track Day

The Bilstein B12 Pro-Kit (46-180049) is a matched monotube damper and Eibach progressive spring set for the BMW E46. It lowers ride height by 25-40mm, sharpening turn-in and reducing body roll without sacrificing daily drivability.

Designed as an integrated system, not a parts-bin mix, it delivers consistent damping and predictable mid-corner composure. No coilover complexity, no re-valving, no guesswork.

• Bilstein monotube dampers with digressive valving for road compliance and track response
• Eibach progressive springs for improved load sensitivity and bump absorption
• Direct bolt-on fitment - no modifications or alignment shims needed
