Bilstein B6 HD Performance DampTronic EDC front left shock / strut for the F80 M3 and F82 M4 with electronic dampening controlled suspension (EDC), as offered in the 2015, 2016, 2017, 2018, 2019 and 2020 model years. This includes the F80 M3 sedan (2015-2019), the F82 M4 Coupe, and the F83 M4 Convertible (2015-2020). For the front left (front driver side on US/LHD cars). 

Only for cars with factory EDC (electronic dampening control), also known as the M Dynamic or M Adaptive suspension. If your M3 or M4 has the button on the shift console to adjust the firmness of your shocks, then your F80/F82 has factory EDC.

If you're looking for added suspension performance - without changing springs or interfering with your M3 or M4 stock electronic dampening control - the Bilstein B6 Series DampTronic shock delivers noticeably better handling without sacrificing your electronic suspension and ride comfort. Bilstein's HD shock is a direct replacements for the originals but with slightly stiffer valving for more control over body and suspension motions. Bilstein uses Digressive Valving on their shocks so fast shock speeds are set for softness (bumps and bad pavement) while slow shock speeds are stiffer (larger dips and cornering). The ride feels more controlled but not stiff and the shock self-adjusts softer to soak up bad pavement. Exceptional control, precise handling, and improved performance but without sacrificing comfort. You'll soon discover there is, quite literally, nothing like it.
