Wilwood 220-11983 Stainless Braided Flexline Kit – BMW E46 M3 Front
Genuine Wilwood stainless steel braided flexline kit, application-specific for the 2001-2006 BMW E46 M3 front brake system, as included in the 140-14978 AERO6-ST big brake front kit. Braided stainless lines resist expansion under hydraulic pressure for a firmer, more consistent pedal feel than OE rubber hoses, and are far more resistant to abrasion, heat, and UV degradation.
Each kit includes 2 lines (one per side), with -3 female straight fittings at both the inlet and outlet, a 1/8-27 NPT 45-degree caliper fitting, and a -3 to M10 x 1 chassis fitting – plus the chassis clip and caliper fitting hardware needed for a complete installation.
