Front Supra GR / BMW Z4 Frenkit Performance Caliper 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.
