ECS Exact-Fit stainless-steel-reinforced brake line kit for the BMW F30/F31/F34. Braided stainless construction resists expansion under hard braking pressure (unlike the factory rubber hoses, which swell over time), giving a firmer, more direct pedal feel and more consistent stopping power.

Fitment: BMW 3 Series, F30/F31/F34 chassis - 320i, 328i/d, 335i and xDrive variants with N20/N26/N55/B58 engines (confirm exact front/rear kit scope at checkout).
