Product Description

The Girodisc A2-049 Rear Brake Rotor Kit is a high-performance, slotted 2-piece brake rotor upgrade designed as a direct replacement for factory PCCB (Porsche Ceramic Composite Brake) rear rotors on select Porsche mid-engine cars. Replacing fragile and expensive ceramic discs with a cast-iron friction ring and lightweight 6061-T6 aluminum hat assembly, this kit significantly improves heat dissipation and brake consistency under high-load driving. Its curved vane design actively pulls cooling air through the rotor, helping resist brake fade during spirited driving or track sessions. Floating mount hardware accommodates thermal growth while maintaining alignment and smooth brake feel. Ideal for Boxster / Cayman models with PCCB, it’s a cost-effective and rebuildable solution that retains factory brake bias and ABS performance. 

Fitment Notes

  • Designed for Porsche 987 Cayman S / R with PCCB

  • Fits Porsche 981 Boxster / Cayman S / GTS with PCCB

  • Fits Porsche 982 718 Boxster / Cayman S / GTS and GTS 4.0 with PCCB

  • Direct bolt-on replacement for OEM PCCB rear rotors — no adapters or machining required

  • Retains factory brake bias and integrates with ABS and PCCB hardware

Included

  • Pair of Girodisc A2-049 rear brake rotors (left and right)

  • CNC-machined 6061-T6 aluminum rotor hats (anodized finish)

  • Proprietary cast-iron friction rings with slotted design

  • Floating mount hardware (steel drive pins, anti-noise washers, fasteners)

Product Specs

  • Rotor assembly: 2-piece floating design (rotor ring + aluminum hat)

  • Hat material: 6061-T6 aircraft-grade aluminum for reduced unsprung mass and corrosion resistance

  • Friction material: proprietary high-carbon cast iron ring for thermal resilience and pad compatibility

  • Cooling design: Curved internal vanes actively channel air for enhanced heat rejection

  • Mounting: floating two-piece rotor with alloy steel drive pins and anti-noise washers

  • Sold and priced as a pair

Product Features

  • Direct PCCB replacement: Works seamlessly with factory PCCB calipers and ABS system, preserving original brake bias and feel without recalibration.

  • Improved heat management: Curved vane design pulls air through the rotor to help keep temperatures in check during repeated hard braking.

  • Rebuildable design: When friction rings wear, only the cast-iron rings need replacement — saving money over one-piece rotor swaps.

  • Reduced unsprung mass: Lightweight aluminum hats lower rotor mass versus OEM PCCB carbon-ceramic discs, aiding handling response.

  • Enhanced pad contact: Slotted rotor surface promotes better pad bite, gas and dust evacuation, and consistent stopping power under load.
