Fitment

  • 2018-2021 Subaru | WRX STI

Description

These brake lines are direct replacements for your factory brake lines that can warp over time or expand under pressure, which can affect your overall braking performance. The FactionFab units feature stainless steel woven construction with Teflon inner liners that will deliver a direct response from the brake pedal straight to the caliper. The result is a faster braking response along with improved braking performance for both street and track use. FACTIONFAB STAINLESS STEEL BRAKE LINES:
  • Rear location
  • PTFE Teflon inner liner to carry the fluid
  • Stainless steel woven middle layer for support of the inner liner
  • Abrasion-resistant, impact-resistant
  • Outer PCV clear abrasion resistant coating to aid in chaffing and protects the inner layers and stress relief at fitting locations
  • Each line is 4500psi burst pressure tested
  • Stainless steel precision machined fittings for perfect fit and corrosion resistance
  • Increased pedal feedback as a result of elimination of soft rubber lines which are prone to swelling and deforming
  • 100% model specific for perfect fitment
  • Includes hardware
