F12 640i 650i 640d Front Left Shock Absorber Bilstein B4 19-227627

Bilstein B4 19-227627 - the no-nonsense, track-day-ready front left damper for F12 6 Series Convertibles (2010-2018). Fits 640i, 650i and 640d. Not a styling part. Not a show-car gimmick. Just proper damping, gas-pressurised, twin-tube, with OE-mount geometry.

• For F12 chassis only - not compatible with F06, F13 or G32. Confirmed fit for N54, N55 and N47 engines
• Stage 1 & fast road friendly - stiffer than stock, but retains daily-driver compliance; pairs well with Eibach Pro-Kit or H&R OE Sport
• Decat or track day? Yes. - handles increased cornering loads and brake dive better than worn OEM units, without needing coilovers
