HEL Performance Brake Lines | Subaru Impreza WRX & STi 2001-2007 GDA GDB

Upgrade the OEM brake lines on your GD Subaru WRX STi with precision-engineered stainless steel braided brake lines by HEL Performance. Each hose, including all fittings and washers, is fully fabricated at their warehouse ensuring that each component meets their rigorous standards. Every hose is DOT Approved for use on streetcars as well as the track.

Every HEL Performance line uses a PTFE inner core wrapped in stainless steel braid and finished with a tough PVC outer layer that protects paint and bodywork. All fittings are CNC-machined from 303/304 stainless steel for unmatched corrosion resistance.

Switching from factory rubber hoses to stainless steel braided lines offers a noticeable improvement in brake pedal feel, responsiveness, and consistency. OEM lines are typically engineered for average street use, and can expand under repeated heavy braking such as that required for Track, Autocross or Rally. This expansion leads to a soft, inconsistent pedal feel and reduced braking confidence. HEL Performance braided lines eliminate that flex entirely. Their durable, high-quality construction ensures your braking system remains precise, reliable, and ready for any driving challenge.

Multiple color options are available from sleek black to vibrant finishes to match your build. Let us know your preference when ordering using the dropdown option!

Each set of lines is backed by HEL Performance's Lifetime Warranty, a wealth of certification standards, and are DOT approved for road use on street cars.

We recommend pairing HEL Performance brake lines with Motul DOT 5.1 brake fluid for street use, and Endless RF650 for street and track use.
