Bilstein B12 Pro Kit - BMW F30 F31 F34 F36 - Part Number 46-229809

Give your BMW 3 Series or 4 Series the driving feel it deserves with the Bilstein B12 Pro Kit. This spring and damper package replaces tired factory components with a perfectly matched performance setup that tightens body control, sharpens steering response and drops the ride height for a purposeful stance. Expect crisp turn-in, reduced roll and a calmer, more settled ride on British roads without the faff of height-adjustable units.

We run this setup ourselves and our customers love it. Feedback is consistently the same: smoother over bumps than worn OE parts, far more confidence in corners, and a smart, even drop that looks just right. If you want a fast-road chassis upgrade that feels OEM-plus, this is the one to fit.

Highlights

  • Matched sport springs and gas-pressure dampers for predictable, confident handling
  • Lower centre of gravity and noticeably flatter cornering for a more connected drive
  • Ride height reduction up to 50 mm model dependent for a clean, level stance
  • Direct-fit replacement with OE-style mounts for straightforward installation
  • Refined road manners - firm, controlled and comfortable for daily use
  • Engineered by Bilstein for longevity, consistency and high-speed stability
  • Ideal non-coilover solution for fast-road builds and subtle lowering

What’s included

A complete sport suspension pack comprising performance shock absorbers and matched lowering springs tailored to the BMW F3x platform. The result is a cohesive spring and damper set that delivers better grip, improved stability and a tasteful drop without compromising everyday drivability.
