Frenkit Performance Brake Caliper Seal Rebuild Kit - Subaru WRX STI (GD/GG) / BRZ (ZC6) - Rear Brembo 36mm
This Frenkit Performance kit reseals one rear Brembo 2-piston caliper with 36mm pistons. It suits the Subaru Impreza WRX STI (GD bugeye, blobeye and hawkeye, 2001-2007) and the Subaru BRZ with Brembo brakes.
Frenkit Performance kits use a high-temperature silicone dust boot and Frenkit's own seal compound, built for track days and hard road driving where standard rubber hardens and cracks.
Note: This kit services one caliper; order two kits for a pair. Suits the 36mm rear Brembo caliper only. If the pistons are pitted, choose the Frenkit Performance piston and seal kit instead. Installation by a professional is recommended.
