Frenkit Performance Front Caliper Seal Kit – Toyota GR Supra / Audi TT RS 8J / Cupra Formentor VZx / Cupra Leon VZx (Brembo)

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

Frenkit Performance uses a high-temperature, peroxide-vulcanised silicone rubber designed specifically for durability and extreme thermal stability. The material maintains full mechanical strength from –60°C to +200°C and withstands short-term temperature spikes up to 300°C without degrading.

Compared to other brands, Frenkit components retain far greater elasticity, tensile strength and tear resistance. After 70 hours at 200°C, Frenkit seals maintain up to 30% more of their original properties than competitors. At 300°C, where other seals crack or become brittle within hours, Frenkit seals remain flexible, stable, and fully functional.
