Blitz Performance Custom Competition PCCB-to-Steel Brake Conversion Kit – Porsche 991 GT3 RS

The Blitz Performance Custom Competition PCCB-to-Steel Brake Conversion Kit is designed for Porsche 991 GT3 RS owners looking for a more track-focused, serviceable, and cost-effective alternative to the factory Porsche Ceramic Composite Brake (PCCB) system.

This complete conversion replaces the factory carbon-ceramic rotors with front and rear 2-piece steel brake rotor assemblies while retaining the original Porsche PCCB brake calipers.

Developed for repeated high-temperature use and track applications, this system allows owners to preserve their original PCCB rotors while significantly reducing long-term brake consumable and replacement costs.

Kit Features

• Complete Front & Rear PCCB-to-Steel Conversion
  Includes application-specific front and rear 2-piece steel rotor assemblies engineered for the Porsche 991 GT3 RS PCCB braking system.
• 2-Piece Competition Steel Rotors – Front & Rear
  High-performance steel friction rings paired with lightweight aluminum rotor hats provide excellent thermal capacity, consistent braking performance, and improved serviceability.
• Retains Factory PCCB Calipers
  Designed to work with the original front and rear Porsche PCCB brake calipers, eliminating the need to replace the factory caliper system.
• Replaceable Steel Friction Rings
  Once the rotors reach their service limit, the steel friction rings can be replaced separately from the aluminum hats, helping reduce long-term maintenance and replacement costs.
• Track-Focused Thermal Performance
  Designed to handle repeated high-temperature braking cycles during demanding track use.
• Reduced PCCB Running Costs
  Allows owners to preserve their original carbon-ceramic rotors and avoid the substantial replacement cost associated with frequent PCCB use on circuit.

Designed for Serious Track Use

While the factory PCCB system provides excellent performance and reduced unsprung mass, carbon-ceramic rotors can be costly to operate under frequent track use.

The Blitz Performance steel conversion provides a practical motorsport solution by converting both the front and rear braking systems to serviceable 2-piece steel rotors while maintaining compatibility with the factory GT3 RS PCCB calipers.

The result is a braking package designed to deliver consistent braking performance, predictable pedal characteristics, excellent thermal capacity, and improved long-term serviceability.
