Frenkit Performance Front Caliper Seal Kit – BMW M3 F80 / BRZ 86 / Civic Type R FK8 FL5 Brembo

This kit services one caliper only. Two kits are required to rebuild a pair of calipers.

Frenkit Performance uses a high-performance, high-temperature peroxide-vulcanised silicone rubber designed for durability. This material maintains excellent mechanical properties between -60°C and +200°C and can withstand temperature spikes up to 300°C without degradation.

The elongation, tensile strength, and tear resistance of Frenkit components are far superior to other brands. Even after aging at 200°C for 70 hours, Frenkit materials retain their properties 30% better than competitors. At 300°C, other manufacturers’ components often crack and become brittle, while Frenkit parts remain flexible, durable, and fully functional under stress.
