Bilstein 46-331007 B12 Sport Damper and Spring Package for BMW F30 F80 F36 xDrive

Transform the way your xDrive BMW steers, grips and sits on the road with the Bilstein B12 package. This complete fast-road setup pairs Bilstein B8 performance shock absorbers with Eibach Pro-Kit progressive springs, delivering a tasteful ride height drop of around 10 to 30 mm depending on model, with outstanding control on British roads.

Expect crisper turn-in, noticeably reduced body roll and better traction without the crashiness you get from cheap lowering springs. We run this solution on customer cars and our own builds, and the feedback is consistently the same: more confidence, neater stance and a composed ride for everyday use and weekend blasts.

Why this B12 kit works

• Matched components for xDrive chassis balance: Bilstein B8 gas-pressure monotube shock absorbers and Eibach Pro-Kit springs
• Fixed ride height sport setup for fast-road use with an elegant drop and OEM+ comfort
• Sharper steering feel, flatter cornering and improved high-speed stability
• Monotube technology for fade-resistant damping and consistent performance
• Progressive-rate springs for compliance over rough UK tarmac with strong body control when loaded
• TÜV approved and designed as a direct-fit replacement for your factory suspension

Who is it ideal for

• Drivers wanting a high-quality, non adjustable sport suspension that outperforms basic lowering springs
• Owners seeking a coilover alternative that keeps comfort and refinement intact
