Description
Upgrade the braking response, pedal feedback, and overall performance of your 2018+ Subaru WRX STI with FactionFab Stainless Steel Brake Lines. Designed as direct replacements for the factory brake lines, these performance brake lines help reduce expansion and flex under braking pressure, providing a more direct connection between the brake pedal and calipers.
Factory rubber brake lines can soften, deform, or expand over time, potentially reducing pedal feedback and contributing to a less responsive braking feel. FactionFab stainless steel brake lines use a reinforced construction with a PTFE Teflon inner liner and stainless steel woven outer reinforcement to help maintain consistent brake fluid pressure and deliver a firmer, more immediate braking response.
Designed for both front and rear brake applications, these lines are suitable for street driving, spirited driving, and track use. The reinforced construction helps maintain consistent performance under demanding braking conditions while providing improved pedal feedback compared with aging factory rubber lines.
Each line features a PTFE Teflon inner liner designed to carry brake fluid, supported by a stainless steel woven middle layer for strength and resistance to expansion. A clear PCV abrasion-resistant outer coating protects the internal layers from abrasion, impacts, and chafing while providing additional protection around fitting and stress-relief locations.
For added durability and reliability, every line is 4500 PSI burst pressure tested. Precision-machined stainless steel fittings provide accurate fitment and enhanced corrosion resistance. The lines are 100% model-specific for the applicable Subaru WRX STI and include installation hardware.
