Front Subaru WRX Sumitomo, Nissan R33 GTS-t, S15 Frenkit Performance Caliper Piston & Seal Kit

This kit will suit one caliper only, two kits required for a pair of calipers. Frenkit Performance uses a high-performance, high-temp peroxide-vulcanized silicone rubber designed for durability. This silicone has excellent mechanical properties, performing reliably between -60°C and +200°C without breaking down and handling temperature spikes up to 300°C with ease. The elongation, tensile strength, and tear resistance found in the Frenkit parts are far superior to other brands; Even after aging at 200°C for 70 hours, Frenkits material retains its properties 30% better than competitors. At higher temperatures, the difference is even more striking: after 2 hours at 300°C, components from other manufacturers crack and become brittle, while Frenkit components remain flexible, durable, and completely functional under stress. 40mm Nissan / Subaru Sumitomo 4-pot Front Caliper Rebuild Kit Included are the following components 40mm High Temp Gray Silicone Dust Boot, Quantity 4 40mm Pressure Seal, Quantity 4 Dust Boot Retaining Clips, Quantity 4 Caliper internal crossover port / channel o-ring seal, Quantity 2 40mm Piston OE specifications, Quantity 4 Bleed Screws, Quantity 2 Bleeder Cap High Temp Gray Silicone, Quantity 1 Caliper Temperature Sticker Replaces: NISSAN 41120-30P26, AY600-NS047, AY600-NS048 SUBARU 26297FA050 Seiken 260-40109, 260-40258, 260-40287 TOYOTA 04479-20260 This kit services one (1) caliper.
