Bilstein B12 Pro Kit Suspension for BMW 6 Series E63 630i - Part No. 46-181176
Upgrade your BMW 6 Series E63 with the Bilstein B12 Pro Kit and transform how your car handles, rides and looks. This is Bilstein’s proven fixed lowering kit that combines Bilstein B8 performance shock absorbers with Eibach Pro-Kit progressive springs for an OEM-plus feel, sharper response and a sportier stance. Perfect for fast-road use and daily driving, the B12 delivers confidence-inspiring control and improved stability without sacrificing comfort.
Important note: the B12 Pro Kit is a matched spring and damper kit with a fixed drop - it is not a height-adjustable coilover system. If you want a reliable, engineered solution that simply works on UK roads, this is it.
