Designed for fast road driving, spirited use, heavy vehicle applications, and track-focused environments, this kit helps maintain optimal caliper performance when exposed 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 heat generated by high-performance braking systems.

Performance Range Key Advantages

High-Temperature Silicone Dust Seals

Performance Range kits feature premium silicone dust seals rather than traditional OEM-style EPDM dust boots.

Benefits include:

• Significantly improved resistance to extreme brake temperatures
• Enhanced flexibility during thermal cycling
• Improved durability during repeated heavy braking
• Reduced risk of heat-related seal deterioration
• Better protection against moisture, dirt and contamination

Enhanced Thermal-Resistant Piston Seals

The piston seals are manufactured using an upgraded high-performance EPDM compound specifically engineered for increased thermal resistance and long-term durability.

Advantages include:

• Improved sealing performance at elevated temperatures
• Enhanced resistance to brake heat
• Increased long-term reliability
• Reduced seal degradation under demanding use
• Consistent caliper performance under extreme conditions

Why Choose the Performance Range?

Large, high-performance Porsche SUVs place significant demands on braking systems, especially during spirited driving, towing, mountain driving, or track-day use.

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

• High operating temperatures
• Repeated heavy braking cycles
• Fast road driving
• Track-day environments
• Performance driving conditions
• Heavy vehicle braking loads

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

Ideal Applications

Perfect for:

• Porsche 955 Cayenne S
• Porsche 955 Cayenne Turbo
• Fast road driving
• Track-day vehicles
• Motorsport-inspired builds
• Heavy-duty road use
• Performance brake system rebuilds
