Chase Bays Brake Line Relocation Kit Subaru WRX / STI 2002-2007

The Chase Bays Brake Line Relocation Kit for Subaru WRX/STi is a complete solution for cleaning up your engine bay, improving braking performance, and adapting to aftermarket master cylinder setups. Whether you're retaining the OEM master cylinder (OEMC) or running the Chase Bays Single Piston Brake Booster Eliminator (BBE), this kit replaces the factory hard lines with lightweight -3AN stainless steel braided lines.

Each line is PTFE-lined and PVC-coated for abrasion resistance and long-term durability. All hose ends are made by Brown & Miller Racing (BMRS) — the same used in NASCAR and IndyCar — and each line is pressure tested before shipping for leak-free performance.

This relocation kit includes a Chase Bays Adjustable Proportioning Valve to fine-tune front-to-rear brake bias, and a chassis-specific mounting bracket for a clean, secure install. Lines are routed low on the firewall, behind the steering column, and under the frame rail for optimal appearance, safety, and clearance from heat sources.

Both versions of the kit relocate and replace all engine bay brake hard lines up to the wheel wells. Caliper lines are not included but are available separately. Two rear lines are joined with our proprietary “F” fitting and can be adapted at the passenger-side shock tower or inside the cabin for an ultra-clean tucked look.

If you're using the Single Piston Brake Booster Eliminator, we include Chase Bays Firesleeve for added protection near high heat sources like manifolds and downpipes.
