The GKTECH FR-S/BRZ braided brake lines are a direct replacement of the factory lines and are stronger (read: more reliable) than the factory rubber lines which are prone to breaking but they also eliminate the spongy feel of the standard brake lines. The front lines are also longer to compensate for big brake setups or cars with more steering lock (which would see stretching with the factory line) These lines are assembled by us in-house in Australia using stainless steel fittings, stainless steel braided line with a Teflon inner tube and PVC outer for protection. Vehicle Compatibility: - Scion FR-S - Toyota ZN6 GT86 - Toyota ZN8 GR86 - Subaru ZC6 BRZ - Subaru ZD8 BRZ
