Frenkit Performance Front Caliper Seal Kit BMW M2/M3/M4 (F22/F80/F82) / Subaru BRZ/Toyota 86 (ZN6/ZC6) / Honda Civic Type R (FK8/FL5) 40mm Brembo 4-Piston

Frenkit Performance Front Caliper Seal Kit - BMW M2/M3/M4 (F22/F80/F82) / Subaru BRZ/Toyota 86 (ZN6/ZC6) / Honda Civic Type R (FK8/FL5) - 40mm Brembo 4-Piston

Frenkit Performance caliper seal kits are built around a high-temperature peroxide-vulcanised silicone rubber compound that simply outlasts conventional materials. Rated for continuous use between -60°C and +200°C with spike resistance up to 300°C, these seals stay flexible and functional where cheaper alternatives crack, harden, and fail. Independent testing shows Frenkit materials retain their mechanical properties 30% better than competitors after sustained heat exposure — a meaningful advantage for track and performance street use.

This listing covers the 40mm Brembo 4-piston front caliper rebuild kit, suitable for BMW M2 (F22), BMW M3 (F80), BMW M4 (F82), Subaru BRZ (ZC6), Toyota 86 (ZN6), Honda Civic Type R (FK8), and Honda Civic Type R (FL5), among other vehicles running the 40mm Brembo 4-piston caliper.

Important: This kit services one (1) caliper only. Two kits are required to rebuild a pair of front calipers.
