Unlike standard caliper rebuild kits, the Performance Range incorporates upgraded high-temperature materials throughout the critical sealing components, helping maintain reliability and braking consistency during repeated heavy braking cycles.

Performance Range Key Advantages

High-Temperature Silicone Dust Seals

The Performance Range replaces conventional OEM-style EPDM dust boots with premium high-temperature silicone dust seals.

Benefits include:

• Superior resistance to elevated brake temperatures
• Increased flexibility under thermal stress
• Improved longevity during track use
• Reduced risk of heat-related seal degradation
• Enhanced protection against dirt, dust and moisture ingress

Enhanced Thermal-Resistant Piston Seals

The piston seals are manufactured using an upgraded EPDM compound specifically developed to withstand higher operating temperatures encountered during performance driving.

Advantages include:

• Improved heat resistance
• Enhanced sealing performance
• Greater long-term reliability
• Reduced seal deterioration under repeated heavy braking
• Consistent caliper operation under demanding conditions

Why Choose the Performance Range?

When brake temperatures rise during aggressive road driving or track use, standard seal materials can become compromised, leading to premature wear and reduced sealing performance.

The upgraded materials used throughout the Performance Range help maintain brake caliper efficiency and durability when exposed to:

• Repeated heavy braking cycles
• High operating temperatures
• Track-day conditions
• Fast road driving
• Motorsport-inspired vehicle builds

This makes the kit an ideal preventative maintenance upgrade for Porsche owners seeking improved brake system reliability.

Ideal Applications

This Performance Brake Caliper Seal Kit is particularly suitable for:

• Porsche 993 Turbo road and track cars
• Porsche GT2 performance builds
• Fast road driving
• Track-day use
• Motorsport-inspired projects
• High-performance braking systems
• Vehicles exposed to repeated high-temperature braking cycles
