Bilstein B12 Pro Kit Sports Suspension Package for BMW F25 X3 and F26 X4 | Part No. 46-257673
Give your BMW X3 F25 or BMW X4 F26 the stance, control and confidence it deserves with Bilstein’s matched spring and damper package. This direct-fit performance kit sharpens steering response, reduces roll and delivers a purposeful ride height that looks right and drives even better. Developed specifically for 2011 to 2017 models, it is a premium road-focused upgrade for drivers who want crisp handling without the faff of height adjustment.

- Engineered vehicle-specific sport dampers paired with performance springs for consistent, predictable handling
- Lowering by up to 50 mm depending on application for a reduced centre of gravity and a more planted feel
- Flatter cornering, improved grip and enhanced stability while retaining day-to-day comfort
