Bilstein B12 Pro Kit 46-237538 for BMW 1 Series F20 F21 xDrive 2011-2018

Give your BMW 1 Series all-wheel-drive chassis the confidence it deserves. The Bilstein B12 Pro Kit pairs precision-matched sport shock absorbers with performance springs to deliver crisp turn-in, flatter cornering and a purposeful ride height drop without ruining day-to-day comfort. Perfect for 118d xDrive and 120d xDrive owners who want a bolt-on handling package that feels OEM-plus on British roads.

Why this upgrade stands out

• Taut, controlled body movement for quick steering response and planted grip in fast bends.
• Ride height reduction for a lower centre of gravity and a clean, aggressive stance.
• Matched dampers and springs for balanced road manners and confidence under braking.
• Designed for the xDrive platform to maintain usability and everyday comfort.
• Proven fast-road solution if you want improved dynamics without committing to coilovers.

What you will feel on the road

Expect tighter responses, reduced roll and calmer weight transfer. The B12 Pro Kit provides a noticeable drop in ride height and up to approximately 50 mm on certain applications, with damping that keeps the car composed on B-roads and motorways alike. It is a genuine step up over tired factory suspension and a favourite with enthusiastic daily drivers.
