Front Supra GR / BMW Z4 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. 40/44mm Brembo Brake Caliper Rebuild Kit Included are the following components : 40mm High Temp Gray Silicone Dust Boot, Quantity 2 40mm Pressure Seal, Quantity 2 44mm High Temp Gray Silicone Dust Boot, Quantity 2 44mm Pressure Seal, Quantity 2 40mm Piston OE specifications, Quantity 2 44mm Piston OE specifications, Quantity 2 Bleed Screw, Quantity 2 Caliper Temperature Sticker , Quantity 1 Bleeder Cap High Temp Gray Silicone, Quantity 2 This kit services one (1) caliper.
