Bilstein B12 Sport Suspension Kit for BMW 6 Series E63 630i Coupe - Part No. 46-181176

Give your BMW E63 630i the chassis it deserves with the Bilstein B12 package. This expertly matched spring and damper set pairs Bilstein B8 performance shocks with Eibach Pro-Kit progressive springs to deliver sharper response, flatter cornering and a purposeful ride height without ruining comfort. Ideal for UK fast-road driving and daily use, it is the OEM-plus handling upgrade that simply works.

What makes it a standout upgrade

• Balanced road handling with reduced body roll, improved turn-in and enhanced mid-corner composure.
• Approximate ride height reduction of 10 to 30 mm depending on specification for a cleaner stance and lower centre of gravity.
• Bilstein B8 gas pressure monotube shocks for precise damping control and stability at speed.
• Eibach Pro-Kit progressive-rate springs to keep comfort on uneven surfaces while adding support when pressing on.
• TUV approved for peace of mind and German-engineered durability.
• Fixed-rate spring and shock pairing - not height adjustable - for a fit-and-forget solution that is easy to live with on British roads.
• Direct replacement using original top mounts for a tidy install and factory-style integration.

Included in the box

• 4 x Bilstein B8 high-performance shock absorbers - monotube gas pressure design.
• 4 x Eibach Pro-Kit performance coil springs - progressive characteristics.
• Application-specific tuning for the BMW 6 Series E63 630i platform.
