Designed for fast road driving, spirited use, track-day events, and performance-focused Porsche ownership, this kit helps maintain optimum caliper performance when subjected to repeated heavy braking and elevated operating temperatures.

Unlike conventional rebuild kits, the Performance Range incorporates upgraded silicone dust seals and enhanced thermal-resistant piston seals specifically developed to withstand the extreme temperatures generated by modern high-performance braking systems.

Performance Range Key Advantages

High-Temperature Silicone Dust Seals

Performance Range kits utilise premium silicone dust seals instead of traditional OEM-style EPDM rubber dust boots.

Benefits include:

• Exceptional resistance to elevated brake temperatures
• Improved flexibility during repeated thermal cycles
• Increased durability under demanding braking conditions
• Reduced risk of heat-related seal degradation
• Enhanced protection against dirt, moisture, and contamination

Enhanced Thermal-Resistant Piston Seals

The piston seals are manufactured using an upgraded EPDM compound developed specifically for high-performance braking applications.

Advantages include:

• Increased resistance to high operating temperatures
• Improved sealing performance under heavy braking loads
• Enhanced long-term reliability
• Greater resistance to thermal fatigue
• Consistent caliper performance during demanding use

Why Choose the Performance Range?

Modern Porsche sports cars are capable of generating extremely high braking forces, particularly during spirited driving and track use. Standard caliper seals can deteriorate more rapidly when repeatedly exposed to elevated temperatures.

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

• Repeated heavy braking cycles
• High operating temperatures
• Fast road driving
• Track-day environments
• Motorsport-inspired applications
• Performance driving conditions

This makes the kit an ideal preventative maintenance upgrade for Porsche owners seeking enhanced brake system durability and performance.

Ideal Applications

Perfect for:

• Porsche 981 Boxster & Cayman
• Porsche 718 Boxster & Cayman
• Porsche 997 Carrera & Turbo models
• Porsche 991 Carrera & Turbo models
• Fast road driving
• Track-day use
• Motorsport-inspired builds
• Brake caliper refurbishment projects
• Vehicles subjected to repeated heavy braking cycles
