Alfa 4C Stainless Brake Lines

$174.00

Stainless braided Teflon core lines for your Alfa Romeo 4C. Motorsport purpose with a durable color sleeve, these lines mean business and improve pedal feeling on our Alfa 4C. Direct replacement for OEM and sold in kits for all 4 corners.

We recommend these specifically for street, fast road, and track use where you will benefit from reduced volumetric expansion of the metal lines, therefore eliminating the "mushy brakes" syndrome caused by rubber brake lines. Maximizing efficiency in your 4C's braking system will allow you to brake later in corners and get onto the accelerator faster. These will add increased pedal feeling.

These stainless lines for the 4C are constructed from the highest quality PTFE flexible hose and stainless steel over braid, both protected by a clear (or colored) weather resistant PVC outer coating. The braided lines feature fully swaged stainless steel fittings and anti-whip collars to provide years of reliable road and track performance. They include all necessary fittings required for fitting and come with a lifetime warranty for the original purchaser.

Following construction, every HEL Performance braided hose is individually pressure tested to ensure high performance and longevity. Rubber grommets included, along with new copper washers.

*Some colors may take longer to build. Expect 2-3 weeks average time.

To maximize performance, Alfa9 recommends using low compressibility brake fluid with these lines, available here.
