BMW F32 4 Series Coupe Handling Package - Bilstein B12 Pro Kit - Part No. 46-280695

Transform the way your BMW F32 4 Series steers, grips and looks with the Bilstein B12 Pro Kit. This expertly matched spring and damper set gives your 430d, 435i or 440i a purposeful ride height, tighter body control and confident fast-road composure while keeping daily comfort intact. It is a direct bolt-on chassis upgrade that feels factory-refined yet distinctly more focused.

What you will feel

• Sharper turn-in and reduced body roll for cornering confidence
• Improved high-speed stability and road feel without the crashiness of cheap lowering springs

Lower, neater, smarter
