StopTech stainless steel brake lines are a great upgrade for your Subaru Legacy GT. The stock rubber brake lines flex, slowing down response, and performance. For your LGT, StopTech stainless steel brake lines do not flex, and will provide a quicker, and more firm pedal response. StopTech uses a Teflon inner line that resists pressure, and will not degrade due to exposure to brake fluid. StopTech stainless steel lines also feature a clear abrasion resistant cover for protection against chaffing. StopTech stainless steel brake lines for the 05-09 Legacy GT are sold as a pair for the front and a pair for the rear.
