Frenkit Performance Rear Brake Caliper Seal Rebuild Kit Porsche 911 GT2/GT3/GT3 Cup (997) / 718 Cayman GT4 (982)

Frenkit Performance Brake Caliper Seal Rebuild Kit Porsche 911 GT2, GT3, GT3 Cup 997/718 Cayman GT4 982 (Rear)

Frenkit Performance has built a strong reputation in motorsport and high performance road applications by engineering seal materials that genuinely outlast the competition. Where standard rubber seals crack and harden under sustained heat, Frenkit's peroxide-vulcanised silicone compound holds its shape and flexibility well beyond what most factory or aftermarket rebuild kits can manage — making this an obvious choice for Porsche 911 and Cayman GT4 owners who push their brakes hard.

This listing covers the rear brake caliper seal rebuild kit, suited to the Porsche 911 GT2, GT3, and GT3 Cup on the 997 platform, as well as the 718 Cayman GT4 (982). One kit services a single caliper — two kits are needed to rebuild a full axle pair.

Important: For 991 GT3 and GT3 RS applications, this kit is only compatible with the factory iron brake setup. It does not suit carbon ceramic (PCCB) calipers.

Key Features

• Peroxide-vulcanised silicone rubber compound — engineered for high temp brake environments
• Rated operating range: -60°C to +200°C, with spike tolerance up to 300°C
• Retains material properties 30% better than competing brands after extended heat soak at 200°C
• Remains flexible and functional after 2 hours at 300°C — where other brands crack and become brittle
• Superior elongation, tensile strength, and tear resistance compared to standard seal materials
• Direct replacement for OE Brembo rebuild kit part numbers (refer to fitment tab)
• One kit services a single caliper

Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please ensure your vehicle's year, trim level, and brake configuration are confirmed before ordering.
