Bilstein B12 Pro-Kit 46-180636 - BMW 3 Series E91 xDrive Estate Fast-Road Suspension Package

Unlock sharper turn-in, flatter cornering and a purposeful ride height drop on your BMW E91 AWD estate with the Bilstein B12 Pro-Kit, part number BILSTEIN-46-180636. This complete handling package combines Bilstein B8 performance shock absorbers with Eibach Pro-Kit progressive springs for a confident, road-focused setup that enhances grip, stability and stance without ruining everyday comfort.

Expect an approximate 10 mm to 30 mm drop depending on model, giving your xDrive touring a lower centre of gravity, reduced squat and dive, and improved high-speed composure on UK B-roads and motorways. The B8 monotube, gas-pressure shock design delivers precise control and fade-resistant performance, while the Eibach springs provide supple ride quality over small bumps with strong support when you push on.
