Stoptech uses a Teflon inner line that resists pressure, and will not degrade due to exposure to brake fluid. The StopTech stainless steel lines also feature a clear abrasion resistant cover for protection against chaffing. Sold as a complete set of all 4 lines.
NOTE: StopTech brake lines differ depending on model and year of your WRX/STi. Please select the appropriate kit for your car
