Frenkit Performance Brake Caliper Rebuild Kit - Subaru WRX (GC/GD/GG) / Nissan 200SX (S15) Skyline (R32/R33/R34) - Sumitomo 4-Pot Front
This Frenkit Performance kit rebuilds one front Sumitomo 4-pot caliper with 40mm pistons, as fitted to the Subaru WRX (GC8 and GD/GG), Nissan Skyline GTS-t (R32/R33/R34), R32 GT-R, 200SX (S15), 300ZX twin turbo (Z32) and Toyota Celica GT-Four (ST205). It includes four new OE-specification pistons along with seals and dust boots.
Frenkit Performance kits use grey high-temperature silicone dust boots and bleeder caps that stay flexible through repeated heat cycles, where standard rubber can harden and crack. Frenkit rates the silicone for continuous use from -60°C to +200°C, and each kit includes a caliper temperature sticker so you can see how hot the caliper has run.
It replaces Nissan 41120-30P26 / AY600-NS047 / AY600-NS048, Subaru 26297FA050, Toyota 04479-20260 and Seiken 260-40109 / 260-40258 / 260-40287.
Note: This kit services one caliper; order two for a pair. Check your front caliper is the Sumitomo 4-pot with 40mm pistons before ordering. Installation by a professional is recommended.
