HEL Performance BMW 3 Series G20 Braided Brake Lines/Hoses/Pipes Kit, Stainless Steel Front & Rear Upgrade (2017+, Non-M3) – Fast Road & Track, PTFE Core, Stainless Fittings

BMW 3 Series G20 Braided Brake Hose Set by HEL Performance

Transform pedal response and braking consistency on your BMW 3 Series G20 with this HEL Performance braided brake hose package. If you are searching for a G20 brake hose upgrade, braided flexi pipes for BMW, uprated steel-braided brake lines, performance brake pipe kit or fast-road and track day brake hoses, this is the go-to solution for dependable, repeatable stopping power.

These precision-made lines use a PTFE inner tube wrapped in stainless braid with stainless fittings to cut out that soft, expanding feel you can get from standard rubber hoses under heat and heavy use. The result is firmer pedal feedback, cleaner modulation and confident braking lap after lap and mile after mile. We have installed these HEL lines at MJ Modifications and customer feedback has been outstanding for feel, finish and long-term durability.
