B12 Pro Kit by Bilstein x Eibach for BMW 6 Series E63 2003-2010 - Part No. 46-181152

Give your E63 a real-world handling upgrade with a matched spring and damper package that tightens body control, sharpens steering and adds a purposeful stance without ruining ride comfort. This complete kit pairs Bilstein B8 short-stroke performance dampers with Eibach progressive-rate coils for a road-focused setup that feels OEM plus, delivers confidence on B-roads and motorways, and looks spot on.

Why enthusiasts choose this upgrade

• Uprated shocks and carefully matched springs for balanced grip and composure in everyday driving and spirited runs
• Ride-height reduction of around 10 mm to 30 mm depending on model for a lower centre of gravity and neater stance
• Noticeably reduced roll, improved turn-in and greater high-speed stability compared with tired factory suspension
• Progressive spring rates maintain comfort over rough surfaces while tightening up cornering support
• Bilstein monotube technology with consistent damping control under heat and load
• OE-level build quality, German engineering and TUV-tested approval for peace of mind

What is included

Four Bilstein B8 performance dampers and four Eibach Pro-Kit progressive springs, pre-selected to work together as a fixed-height, direct-fit replacement for the factory components. No guesswork, no mismatched parts, just a cohesive fast-road setup.

Lowering range

Typical drop: approximately 10 mm to 30 mm depending on the exact E63 variant. The result is a lower stance, crisper response and a more planted feel without going too low for daily use.

Fitment

• BMW 6 Series E63 09-2003 to 12-2010
• Compatible models: 645Ci, 650i, 635d
