The GKTECH ZN6 FR-S/ ZC6 BRZ dual caliper bracket allows for simple installation of a secondary rear brake caliper for your drift car when running a stand-alone hydraulic e-brake kit. This is also the only bracket that we're aware of that retains the factory drum handbrake. Compatible with OEM FR-S/BRZ calipers. There are 3 variants that were used across various versions and all can be used. The only caveat to this is that you must use matching calipers. Eg. if your vehicle uses Brembo calipers, you must use a matching Brembo caliper (and rotor) - Brackets are CNC Machined from 6061-T6 Aluminium - Includes required bolts for secondary calipers - Allows for the use of the factory OEM ebrake (when purchasing the optional bolt kit) If you don't want to waste time shopping around for all the individual parts, getting custom brake lines made up, or running generic parts that may or may not work and check out our complete kit. Vehicle Compatibility: - Scion FR-S - Subaru ZC6 BRZ - Toyota ZN6 GT86
