Frenkit Performance Brake Caliper Seal Rebuild Kit Subaru WRX (GD/GR) / Nissan 200SX (S14/S15) Skyline (R32/R33/R34) Sumitomo 4-Pot Front

Frenkit Performance Brake Caliper Seal Rebuild Kit Subaru WRX/Nissan 200SX/Skyline (Front, Sumitomo 4pot Caliper)

When your front calipers start weeping fluid or the pedal feel goes soft, a quality rebuild kit makes all the difference. Frenkit Performance seals are made from a peroxide-vulcanised silicone rubber compound engineered to outperform standard EPDM seals in both longevity and heat resistance — making this kit a solid choice for Subaru WRX, Nissan 200SX, and Nissan Skyline owners running the factory Sumitomo 4-piston front caliper.

This listing covers the front caliper seal rebuild kit for vehicles fitted with the Sumitomo 4-piston front brake caliper, including the Subaru WRX (GC/GD/GE platforms), Nissan 200SX (S14/S15), and Nissan Skyline (R32/R33/R34). SKU: 664005.

Note: This kit suits the Sumitomo 4-piston front caliper only. Confirm your caliper manufacturer and piston count before ordering, as fitment will vary between vehicles and any aftermarket caliper upgrades.

Key Features

• Peroxide-vulcanised silicone rubber construction — not standard EPDM
• Operating temperature range: -60°C to +200°C, with spike tolerance up to 300°C
• After 70 hours at 200°C, retains material properties approximately 30% better than competing brands
• Remains flexible and functional after 2 hours at 300°C — where standard seals crack and become brittle
• Superior elongation, tensile strength, and tear resistance compared to OEM-spec rubber compounds
• Direct replacement for Sumitomo 4-piston front calipers — no machining required
• Suits both street and track use where elevated brake temperatures are common

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