For G20 3 Series and G80 M3 xDrive owners wanting a fast-road or track-day suspension upgrade that’s stiffer than OEM but more compliant than full coilovers - this is the B12 Pro-Kit you’ve searched for.

It’s not ‘OEM replacement’. It’s Bilstein B8 monotube dampers (upside-down front, gas-pressure monotube rear) matched precisely to Eibach Pro-Kit progressive springs. Drop: 10-30 mm depending on model. No coding, no warning lights, no compatibility headaches - fits G20 320i/330i/320d/330d/M340i xDrive and G80 M3 xDrive (2019+).

• Stage 1 & fast-road fit: Sharper turn-in, reduced squat/lift, zero float - without wrecking your daily driver comfort
• Track-day ready: B8s resist fade; Eibach springs maintain linearity under load - no wallow, no bottoming
