E46 330d 330Cd Bilstein B12 Pro Kit B8 + Eibach Pro-Kit 46-331687

For E46 330d and 330Cd (2004-2007) owners wanting fast road or track day composure without coilover complexity - this is the matched B8 damper and Eibach Pro-Kit spring set, sold as the official Bilstein B12 Pro Kit.

• Chassis-specific: tuned for E46 diesel front/rear geometry and axle loads - not a generic 'BMW' kit
• Stage 1 & fast road fit: 25-30 mm front / 15-20 mm rear drop; retains ride comfort on UK roads while sharpening turn-in
• No decat required: unlike some aggressive setups, this works with stock exhaust and bump stops
• Track day ready: monotube B8s handle repeated heat; Eibach’s progressive wind gives control mid-corner and compliance over kerbs
